В принципе, и 8910, но разводка платы будет другая. 5 | Снаружи 50 раз в секунду в атмегу по UART пихается 16 байт - дамп регистров. 6 | 7 | Прошивка Atmega с исходником - в папке atmega. Пример "пихающей" YM-файл программы на питоне в папке host. 8 | 9 | В pcb - разводка платы под Atmega8, AY-3-8912, счетчик-делитель на 2. Кварц атмеги можно не распаивать, на 8 МГц от внутреннего колебатора все работает ок. Кварцевый генератор для AY - на 4 или 3.5... МГц (для Atari или Speccy). Если поставить генератор на 2 МГц, счетчик можно выкинуть. 10 | 11 | host-un_def - альтернативный вариант скрипта хоста, выглядит более серьезно. 12 | -------------------------------------------------------------------------------- /.gitignore: -------------------------------------------------------------------------------- 1 | #

Использует модуль ```ymfile```. 5 | 6 | ### Использование 7 | 8 | ```streamer.py -p port [-b bd] [-u] [-l] [-v] file.ym``` 9 | 10 | ```-h```, ```--help``` — показать помощь. 11 | 12 | ```-p```, ```--port``` — устройство последовательного порта (например, **COM6**, **/dev/ttyUSB0** и т.п.). Обязательный аргумент. 13 | 14 | ```-b```, ```--baudrate``` — скорость последовательного порта (по умолчанию **38400**). 15 | 16 | ```-u```, ```--unbuf``` — использовать небуферизированный режим работы (см. ниже). 17 | 18 | ```-l```, ```--loop``` — зацикленное воспроизведение (после окончания трека переход на ```loop_frame```, указанный в заголовке файла). 19 | 20 | ```-v```, ```--verbose``` — показать всю информацию о файле, возвращаемую ```ymfile.load()```, в виде **ключ: значение**. По умолчанию отображается только название трека, автор, комментарий и продолжительность (в форматированном виде). 21 | 22 | ### Режимы работы 23 | 24 | Поддержка режимов зависит от прошивки устройства. 25 | 26 | ##### Буферизированный 27 | Режим по умолчанию. Ожидание запроса данных от устройства (байт **0x08**), по запросу отправка 256 байтов (16 фреймов). Тактование осуществляется самим устройством, которое хранит фреймы в своём кольцевом буфере и запрашивает новые данные по мере необходимости. 28 | 29 | ##### Небуферизированный 30 | Включается ключом ```-u``` / ```--unbuf```. Устройство не запрашивает данные, скрипт отправляет фреймы (16 байтов) по одному с задержкой между ними в 1/```frame_freq``` секунд (при частоте 50 Гц — 0.02 с). 31 | 32 | ### О реализации режимов 33 | В небуферизированном режиме при обычном воспроизведении после последнего фрейма отправляется один пустой фрейм (16 байтов **0x00**), чтобы приглушить AY, и работа скрипта завершается. При зацикленном воспроизведении осуществяется переход на ```loop_frame``` (указан в заголовке файла). Если ```loop_frame``` = 0, то воспроизведение начнётся с начала файла. 34 | 35 | В буферизированном режиме при обычном воспроизведении блок с последним фреймом заполняется нулевыми байтами до размера в 256 байтов (в случае необходимости, т.е. когда общее количество фреймов в файле не кратно 16), после этого скрипт ожидает ещё два запроса от устройства, на каждый из которых отправляет 256 нулевых байтов (чтобы полностью очистить кольцевой буфер устройства, который в данной реализации имеет размер 512 байтов) и завершает работу. При зацикленном воспроизведении в блок данных следом за последним фреймом записывается ```loop_frame``` и последующие за ним. 36 | -------------------------------------------------------------------------------- /old(no_buffer)/atmega/main.c: -------------------------------------------------------------------------------- 1 | #define F_CPU 8000000UL 2 | #include 3 | #include 4 | #include 5 | 6 | //DA0 PB2 7 | //DA1 PB3 8 | //DA2 PB4 9 | //DA3 PB5 10 | //DA4 PC0 11 | //DA5 PC1 12 | //DA6 PC2 13 | //DA7 PC3 14 | //BC1 PC4 15 | //BC2 +Vcc 16 | //BDIR PC5 17 | 18 | unsigned char buffer[16]; // буфер принятых данных 19 | unsigned char bytesReceived; // Счетчик принятых байт 20 | 21 | // Инициализация 22 | void setup(void) 23 | { 24 | // режим портов 25 | DDRB = 0b11111111; 26 | DDRC = 0b00111111; 27 | 28 | 29 | // настройка последовательного интерфейса 30 | 31 | // устанавливаем стандартный режим 8N1 32 | UCSRC=(1<>= 4; 59 | 60 | // записать полученное в порты 61 | PORTB = PBPart; 62 | PORTC = PCPart; 63 | } 64 | 65 | // отправка в регистр AY значения 66 | void sendToAY(unsigned int addr, unsigned int data) 67 | { 68 | //неактивный режим: BC1=0, BDIR=0 69 | PORTC &= 0b11001111; 70 | 71 | //установка адреса 72 | valToPort(addr); 73 | 74 | //фиксация адреса: BC1=1, BDIR=1 75 | PORTC |= 0b00110000; 76 | _delay_us(1); 77 | PORTC &= 0b11001111; 78 | 79 | //установка значения 80 | valToPort(data); 81 | 82 | //фиксация значения: BC1=0, BDIR=1 83 | PORTC |= 0b00100000; 84 | _delay_us(1); 85 | PORTC &= 0b11011111; 86 | } 87 | 88 | 89 | int main(void) 90 | { 91 | setup(); // Инициализация 92 | 93 | while(1) 94 | { 95 | // принимаем 16 байт 96 | for (bytesReceived=0; bytesReceived<16; bytesReceived++) 97 | { 98 | // ждем приемник 99 | while(!(UCSRA & (1< null-terminated string 45 | if length: 46 | return fo.read(length).decode(encoding) 47 | buff = bytearray() 48 | while True: 49 | byte = fo.read(1) 50 | if not byte or byte == b'\x00': 51 | break 52 | buff.extend(byte) 53 | return buff.decode(encoding) 54 | 55 | def read_int(fo, length, byteorder='big'): 56 | return int.from_bytes(fo.read(length), byteorder) 57 | 58 | def load(fo): 59 | is_lha = fo.read(5).endswith(b'-lh') 60 | fo.seek(0) 61 | if is_lha: 62 | if not lhafile: 63 | raise YMFileException("Compressed file; install 'lhafile'") 64 | else: 65 | lha = lhafile.LhaFile(fo) 66 | lha_filename = lha.namelist()[0] 67 | fo = io.BytesIO(lha.read(lha_filename)) 68 | ym = {} 69 | for field, data_type, length in header: 70 | if data_type == 'skip': 71 | fo.seek(length, 1) 72 | continue 73 | if data_type == 'digidrum': 74 | if ym['digidrums']: 75 | for i in range(ym['digidrums']): 76 | sample_size = read_int(fo, 4) 77 | fo.seek(sample_size, 1) 78 | continue 79 | read = read_int if data_type == 'int' else read_str 80 | value = read(fo, length) 81 | if field == 'file_id' and value not in supported_formats: 82 | raise YMFileException("Unsupported format: " + value) 83 | ym[field] = value 84 | interleaved = bool(ym['attributes'] & 1) 85 | if interleaved: 86 | chunks = 16 87 | chunk_size = ym['frames'] 88 | else: 89 | chunks = ym['frames'] 90 | chunk_size = 16 91 | data = [] 92 | for i in range(chunks): 93 | chunk = fo.read(chunk_size) 94 | if len(chunk) < chunk_size: 95 | raise YMFileException("Truncated file") 96 | data.append(chunk) 97 | end_marker = fo.read(4) 98 | if len(end_marker) < 4: 99 | raise YMFileException("Truncated file") 100 | elif end_marker != b'End!': 101 | raise YMFileException("Wrong end marker: " + str(end_marker)) 102 | ym['interleaved'] = interleaved 103 | ym['data'] = data 104 | ym['compressed'] = is_lha 105 | if is_lha: 106 | ym['compressed_filename'] = lha_filename 107 | fo.close() 108 | ym['length'] = round(ym['frames'] / ym['frame_freq']) 109 | return ym 110 | 111 | def get_frame(data, frame, interleaved=True): 112 | if interleaved: 113 | frame_data = bytearray() 114 | for reg in range(16): 115 | frame_data.append(data[reg][frame]) 116 | return bytes(frame_data) 117 | else: 118 | return data[frame] 119 | -------------------------------------------------------------------------------- /old(no_buffer)/host/streamer.py: -------------------------------------------------------------------------------- 1 | import serial, struct, time 2 | # from datetime import datetime 3 | 4 | 5 | # параметры COM порта 6 | comPort = "COM6" 7 | baudRate = 38400 8 | 9 | # тишина 10 | silenceTone = [0x00 for dummyCounter in range(0,16)] 11 | 12 | def readNullTermString(fileConn): 13 | """ 14 | Для обработки заголовка YM-файла.

Экспортирует следующие объекты: 5 | 6 | _ymfile.**supported_formats**_ — кортеж поддерживаемых форматов (сигнатуры файлов). На данный момент поддерживаются два формата — **'YM5!'** и **'YM6!'**. 7 | 8 | _ymfile.**header**_ — описание структуры заголовка файла в виде кортежа кортежей. Используется ```ymfile.load()``` при парсинге файла. 9 | 10 | _ymfile.**YMFileException**_ — исключение. Вызывается при ошибках в ```ymfile.load()```. 11 | 12 | _ymfile.**read_str**(fo, length=None, encoding='ascii')_ — прочитать из file-like object ```fo``` (например, открытый в режиме 'rb' файл) строку длиной ```length``` байтов. Если ```length``` не указана или **False** в логическом контексте, то читать до байта **0x00** (**null-terminated string**) или конца файла. Дополнительно можно указать кодировку ```encoding```. Для многобайтовых кодировок необходимо учитывать, что ```length``` указывается в **байтах**. 13 | 14 | _ymfile.**read_int**(fo, length, byteorder='big')_ — прочитать из file-like object ```fo``` число длиной ```length``` байтов и порядком байтов ```byreorder``` (**'big'** или **'little'**). 15 | 16 | _ymfile.**load**(fo)_ — прочитать .ym-файл из file-like object ```fo```. Файл может быть сжат с помощью **LHA**, для распаковки требуется модуль **[lhafile][1]** (сжатый файл определяется по фрагменту сигнатуры **'-lh'**). В случае успеха возвращает словарь со следующими ключами: 17 | 18 | * str ```file_id``` — сигнатура файла (например, **'YM6!'**). 19 | * str ```check_string``` — проверочная строка. Для YM6 должна быть **'LeOnArD!'**. 20 | * int ```frames``` — количество фреймов в файле. 21 | * int ```attributes``` — атрибуты в виде 32-битного числа. Из спецификации: 22 | * **b0**: Set if Interleaved data block. 23 | * **b1**: Set if the digi-drum samples are signed data. 24 | * **b2**: Set if the digidrum is already in ST 4 bits format. 25 | * **b3-b31**: Not used yet, MUST BE 0. 26 | * int ```digidrums``` — количество **digidrum** семплов (при парсинге они игнорируются). 27 | * int ```clock``` — частота AY/YM в Гц. Например, 2000000 для Atari ST, 1773400 для оригинального ZX Spectrum. 28 | * int ```frame_freq``` — частота фреймов в Гц (обычно 50 Гц). 29 | * int ```loop_frame``` — номер фрейма для зацикленного воспроизведения. Например, при **0** трек будет проигрываться по кругу с начала. 30 | * str ```song_name``` — название трека. 31 | * str ```author``` — автор трека. 32 | * str ```comment``` — комментарий. 33 | * int ```length``` — продолжительность трека в секундах, вычисленная как round(```frames``` / ```frame_freq```). 34 | * bool ```interleaved``` — **True**, если фреймы хранятся в чередующемся порядке (нулевой бит ```attributes```). 35 | * bool ```compressed``` — **True**, если файл сжат с помощью **LHA**. 36 | * str ```compressed_filename``` — (только для сжатых файлов) оригинальное имя файла (внутри архива). 37 | * list ```data``` — данные фреймов в виде списка байтов (объектов **bytes**). Формат хранения зависит от режима — чередующийся или нет (см. ```interleaved```). 38 | * для обычного режима — [фрейм0, фрейм1, …, фреймN]. Каждый фрейм — объект **bytes** длиной 16 байтов (дамп регистров). Количество фреймов соответствует ```frames```. 39 | * для чередующегося режима — [регистр0, регистр1, …, регистр15]. Каждый регистр — объект **bytes** длиной ```frames```, каждый байт N регистра соответствует значению этого регистра во фрейме N. 40 | 41 | ```ymfile.load()``` вызывает исключение ```ymfile.YMFileException``` в следующих случаях: 42 | 43 | * *Compressed file; install 'lhafile'* — файл сжат с помошью **LHA**, но модуль **[lhafile][1]** не найден. 44 | * *Unsupported format* — сигнатура файла не соответствует поддерживаемым форматам (см. ```ymfile.supported_formats```). 45 | * *Truncated file* — размер блока с фреймами меньше ожидаемого (```frames``` * 16). 46 | * *Wrong end marker* — неправильный/отсутствующий маркер конца файла (должен быть **'End!'**). 47 | 48 | ```ymfile.load()``` не обрабатывает исключения (например, при чтении из файла) — их необходимо перехватывать в вызывающем коде. 49 | 50 | _ymfile.**get_frame**(data, frame, interleaved=True)_ — извлечь фрейм номер ```frame``` из ```data``` (данные фреймов в списке, возвращаемом ```ymfile.load()``` в словаре под ключом ```data```). Флаг ```interleaved``` указывает на формат хранения фреймов в ```data```. Корректность номера фрейма не проверяется, выход за границы вызовет **IndexError**. Фрейм возвращается в виде объекта **bytes** длиной 16 байтов. 51 | 52 | 53 | ### Пример использования: 54 | 55 | ```python 56 | import ymfile 57 | with open('file.ym', 'rb') as f: 58 | try: 59 | ym = ymfile.load(f) 60 | except ymfile.YMFileException as e: 61 | print("Error:", e) 62 | else: 63 | print("Track", ym['song_name'], "by", ym['author']) 64 | first_frame = ymfile.get_frame(ym['data'], 0, ym['interleaved']) 65 | print(first_frame) 66 | ``` 67 | 68 | 69 | [1]: http://fengestad.no/python-lhafile/ 70 | -------------------------------------------------------------------------------- /atmega/main.c: -------------------------------------------------------------------------------- 1 | /* 2 | 1.

By contrast, 15 | the GNU General Public License is intended to guarantee your freedom to 16 | share and change all versions of a program--to make sure it remains free 17 | software for all its users. We, the Free Software Foundation, use the 18 | GNU General Public License for most of our software; it applies also to 19 | any other work released this way by its authors. You can apply it to 20 | your programs, too. 21 | 22 | When we speak of free software, we are referring to freedom, not 23 | price. Our General Public Licenses are designed to make sure that you 24 | have the freedom to distribute copies of free software (and charge for 25 | them if you wish), that you receive source code or can get it if you 26 | want it, that you can change the software or use pieces of it in new 27 | free programs, and that you know you can do these things. 28 | 29 | To protect your rights, we need to prevent others from denying you 30 | these rights or asking you to surrender the rights. Therefore, you have 31 | certain responsibilities if you distribute copies of the software, or if 32 | you modify it: responsibilities to respect the freedom of others. 33 | 34 | For example, if you distribute copies of such a program, whether 35 | gratis or for a fee, you must pass on to the recipients the same 36 | freedoms that you received. You must make sure that they, too, receive 37 | or can get the source code. And you must show them these terms so they 38 | know their rights. 39 | 40 | Developers that use the GNU GPL protect your rights with two steps: 41 | (1) assert copyright on the software, and (2) offer you this License 42 | giving you legal permission to copy, distribute and/or modify it. 43 | 44 | For the developers' and authors' protection, the GPL clearly explains 45 | that there is no warranty for this free software. For both users' and 46 | authors' sake, the GPL requires that modified versions be marked as 47 | changed, so that their problems will not be attributed erroneously to 48 | authors of previous versions. 49 | 50 | Some devices are designed to deny users access to install or run 51 | modified versions of the software inside them, although the manufacturer 52 | can do so. This is fundamentally incompatible with the aim of 53 | protecting users' freedom to change the software. The systematic 54 | pattern of such abuse occurs in the area of products for individuals to 55 | use, which is precisely where it is most unacceptable. Therefore, we 56 | have designed this version of the GPL to prohibit the practice for those 57 | products. If such problems arise substantially in other domains, we 58 | stand ready to extend this provision to those domains in future versions 59 | of the GPL, as needed to protect the freedom of users. 60 | 61 | Finally, every program is threatened constantly by software patents. 62 | States should not allow patents to restrict development and use of 63 | software on general-purpose computers, but in those that do, we wish to 64 | avoid the special danger that patents applied to a free program could 65 | make it effectively proprietary. To prevent this, the GPL assures that 66 | patents cannot be used to render the program non-free. 67 | 68 | The precise terms and conditions for copying, distribution and 69 | modification follow. 70 | 71 | TERMS AND CONDITIONS 72 | 73 | 0. Definitions. 74 | 75 | "This License" refers to version 3 of the GNU General Public License. 76 | 77 | "Copyright" also means copyright-like laws that apply to other kinds of 78 | works, such as semiconductor masks. 79 | 80 | "The Program" refers to any copyrightable work licensed under this 81 | License. Each licensee is addressed as "you". "Licensees" and 82 | "recipients" may be individuals or organizations. 83 | 84 | To "modify" a work means to copy from or adapt all or part of the work 85 | in a fashion requiring copyright permission, other than the making of an 86 | exact copy. The resulting work is called a "modified version" of the 87 | earlier work or a work "based on" the earlier work. 88 | 89 | A "covered work" means either the unmodified Program or a work based 90 | on the Program. 91 | 92 | To "propagate" a work means to do anything with it that, without 93 | permission, would make you directly or secondarily liable for 94 | infringement under applicable copyright law, except executing it on a 95 | computer or modifying a private copy. Propagation includes copying, 96 | distribution (with or without modification), making available to the 97 | public, and in some countries other activities as well. 98 | 99 | To "convey" a work means any kind of propagation that enables other 100 | parties to make or receive copies. Mere interaction with a user through 101 | a computer network, with no transfer of a copy, is not conveying. 102 | 103 | An interactive user interface displays "Appropriate Legal Notices" 104 | to the extent that it includes a convenient and prominently visible 105 | feature that (1) displays an appropriate copyright notice, and (2) 106 | tells the user that there is no warranty for the work (except to the 107 | extent that warranties are provided), that licensees may convey the 108 | work under this License, and how to view a copy of this License. If 109 | the interface presents a list of user commands or options, such as a 110 | menu, a prominent item in the list meets this criterion. 111 | 112 | 1. Source Code. 113 | 114 | The "source code" for a work means the preferred form of the work 115 | for making modifications to it. "Object code" means any non-source 116 | form of a work. 117 | 118 | A "Standard Interface" means an interface that either is an official 119 | standard defined by a recognized standards body, or, in the case of 120 | interfaces specified for a particular programming language, one that 121 | is widely used among developers working in that language. 122 | 123 | The "System Libraries" of an executable work include anything, other 124 | than the work as a whole, that (a) is included in the normal form of 125 | packaging a Major Component, but which is not part of that Major 126 | Component, and (b) serves only to enable use of the work with that 127 | Major Component, or to implement a Standard Interface for which an 128 | implementation is available to the public in source code form. A 129 | "Major Component", in this context, means a major essential component 130 | (kernel, window system, and so on) of the specific operating system 131 | (if any) on which the executable work runs, or a compiler used to 132 | produce the work, or an object code interpreter used to run it. 133 | 134 | The "Corresponding Source" for a work in object code form means all 135 | the source code needed to generate, install, and (for an executable 136 | work) run the object code and to modify the work, including scripts to 137 | control those activities. However, it does not include the work's 138 | System Libraries, or general-purpose tools or generally available free 139 | programs which are used unmodified in performing those activities but 140 | which are not part of the work. For example, Corresponding Source 141 | includes interface definition files associated with source files for 142 | the work, and the source code for shared libraries and dynamically 143 | linked subprograms that the work is specifically designed to require, 144 | such as by intimate data communication or control flow between those 145 | subprograms and other parts of the work. 146 | 147 | The Corresponding Source need not include anything that users 148 | can regenerate automatically from other parts of the Corresponding 149 | Source. 150 | 151 | The Corresponding Source for a work in source code form is that 152 | same work. 153 | 154 | 2. Basic Permissions. 155 | 156 | All rights granted under this License are granted for the term of 157 | copyright on the Program, and are irrevocable provided the stated 158 | conditions are met. This License explicitly affirms your unlimited 159 | permission to run the unmodified Program. The output from running a 160 | covered work is covered by this License only if the output, given its 161 | content, constitutes a covered work. This License acknowledges your 162 | rights of fair use or other equivalent, as provided by copyright law. 163 | 164 | You may make, run and propagate covered works that you do not 165 | convey, without conditions so long as your license otherwise remains 166 | in force. You may convey covered works to others for the sole purpose 167 | of having them make modifications exclusively for you, or provide you 168 | with facilities for running those works, provided that you comply with 169 | the terms of this License in conveying all material for which you do 170 | not control copyright. Those thus making or running the covered works 171 | for you must do so exclusively on your behalf, under your direction 172 | and control, on terms that prohibit them from making any copies of 173 | your copyrighted material outside their relationship with you. 174 | 175 | Conveying under any other circumstances is permitted solely under 176 | the conditions stated below. Sublicensing is not allowed; section 10 177 | makes it unnecessary. 178 | 179 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 180 | 181 | No covered work shall be deemed part of an effective technological 182 | measure under any applicable law fulfilling obligations under article 183 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 184 | similar laws prohibiting or restricting circumvention of such 185 | measures. 186 | 187 | When you convey a covered work, you waive any legal power to forbid 188 | circumvention of technological measures to the extent such circumvention 189 | is effected by exercising rights under this License with respect to 190 | the covered work, and you disclaim any intention to limit operation or 191 | modification of the work as a means of enforcing, against the work's 192 | users, your or third parties' legal rights to forbid circumvention of 193 | technological measures. 194 | 195 | 4. Conveying Verbatim Copies. 196 | 197 | You may convey verbatim copies of the Program's source code as you 198 | receive it, in any medium, provided that you conspicuously and 199 | appropriately publish on each copy an appropriate copyright notice; 200 | keep intact all notices stating that this License and any 201 | non-permissive terms added in accord with section 7 apply to the code; 202 | keep intact all notices of the absence of any warranty; and give all 203 | recipients a copy of this License along with the Program. 204 | 205 | You may charge any price or no price for each copy that you convey, 206 | and you may offer support or warranty protection for a fee. 207 | 208 | 5. Conveying Modified Source Versions. 209 | 210 | You may convey a work based on the Program, or the modifications to 211 | produce it from the Program, in the form of source code under the 212 | terms of section 4, provided that you also meet all of these conditions: 213 | 214 | a) The work must carry prominent notices stating that you modified 215 | it, and giving a relevant date. 216 | 217 | b) The work must carry prominent notices stating that it is 218 | released under this License and any conditions added under section 219 | 7. This requirement modifies the requirement in section 4 to 220 | "keep intact all notices". 221 | 222 | c) You must license the entire work, as a whole, under this 223 | License to anyone who comes into possession of a copy. This 224 | License will therefore apply, along with any applicable section 7 225 | additional terms, to the whole of the work, and all its parts, 226 | regardless of how they are packaged. This License gives no 227 | permission to license the work in any other way, but it does not 228 | invalidate such permission if you have separately received it. 229 | 230 | d) If the work has interactive user interfaces, each must display 231 | Appropriate Legal Notices; however, if the Program has interactive 232 | interfaces that do not display Appropriate Legal Notices, your 233 | work need not make them do so. 234 | 235 | A compilation of a covered work with other separate and independent 236 | works, which are not by their nature extensions of the covered work, 237 | and which are not combined with it such as to form a larger program, 238 | in or on a volume of a storage or distribution medium, is called an 239 | "aggregate" if the compilation and its resulting copyright are not 240 | used to limit the access or legal rights of the compilation's users 241 | beyond what the individual works permit. Inclusion of a covered work 242 | in an aggregate does not cause this License to apply to the other 243 | parts of the aggregate. 244 | 245 | 6. Conveying Non-Source Forms. 246 | 247 | You may convey a covered work in object code form under the terms 248 | of sections 4 and 5, provided that you also convey the 249 | machine-readable Corresponding Source under the terms of this License, 250 | in one of these ways: 251 | 252 | a) Convey the object code in, or embodied in, a physical product 253 | (including a physical distribution medium), accompanied by the 254 | Corresponding Source fixed on a durable physical medium 255 | customarily used for software interchange. 256 | 257 | b) Convey the object code in, or embodied in, a physical product 258 | (including a physical distribution medium), accompanied by a 259 | written offer, valid for at least three years and valid for as 260 | long as you offer spare parts or customer support for that product 261 | model, to give anyone who possesses the object code either (1) a 262 | copy of the Corresponding Source for all the software in the 263 | product that is covered by this License, on a durable physical 264 | medium customarily used for software interchange, for a price no 265 | more than your reasonable cost of physically performing this 266 | conveying of source, or (2) access to copy the 267 | Corresponding Source from a network server at no charge. 268 | 269 | c) Convey individual copies of the object code with a copy of the 270 | written offer to provide the Corresponding Source. This 271 | alternative is allowed only occasionally and noncommercially, and 272 | only if you received the object code with such an offer, in accord 273 | with subsection 6b. 274 | 275 | d) Convey the object code by offering access from a designated 276 | place (gratis or for a charge), and offer equivalent access to the 277 | Corresponding Source in the same way through the same place at no 278 | further charge. You need not require recipients to copy the 279 | Corresponding Source along with the object code. If the place to 280 | copy the object code is a network server, the Corresponding Source 281 | may be on a different server (operated by you or a third party) 282 | that supports equivalent copying facilities, provided you maintain 283 | clear directions next to the object code saying where to find the 284 | Corresponding Source. Regardless of what server hosts the 285 | Corresponding Source, you remain obligated to ensure that it is 286 | available for as long as needed to satisfy these requirements. 287 | 288 | e) Convey the object code using peer-to-peer transmission, provided 289 | you inform other peers where the object code and Corresponding 290 | Source of the work are being offered to the general public at no 291 | charge under subsection 6d. 292 | 293 | A separable portion of the object code, whose source code is excluded 294 | from the Corresponding Source as a System Library, need not be 295 | included in conveying the object code work. 296 | 297 | A "User Product" is either (1) a "consumer product", which means any 298 | tangible personal property which is normally used for personal, family, 299 | or household purposes, or (2) anything designed or sold for incorporation 300 | into a dwelling. In determining whether a product is a consumer product, 301 | doubtful cases shall be resolved in favor of coverage. For a particular 302 | product received by a particular user, "normally used" refers to a 303 | typical or common use of that class of product, regardless of the status 304 | of the particular user or of the way in which the particular user 305 | actually uses, or expects or is expected to use, the product. A product 306 | is a consumer product regardless of whether the product has substantial 307 | commercial, industrial or non-consumer uses, unless such uses represent 308 | the only significant mode of use of the product. 309 | 310 | "Installation Information" for a User Product means any methods, 311 | procedures, authorization keys, or other information required to install 312 | and execute modified versions of a covered work in that User Product from 313 | a modified version of its Corresponding Source. The information must 314 | suffice to ensure that the continued functioning of the modified object 315 | code is in no case prevented or interfered with solely because 316 | modification has been made. 317 | 318 | If you convey an object code work under this section in, or with, or 319 | specifically for use in, a User Product, and the conveying occurs as 320 | part of a transaction in which the right of possession and use of the 321 | User Product is transferred to the recipient in perpetuity or for a 322 | fixed term (regardless of how the transaction is characterized), the 323 | Corresponding Source conveyed under this section must be accompanied 324 | by the Installation Information. But this requirement does not apply 325 | if neither you nor any third party retains the ability to install 326 | modified object code on the User Product (for example, the work has 327 | been installed in ROM). 328 | 329 | The requirement to provide Installation Information does not include a 330 | requirement to continue to provide support service, warranty, or updates 331 | for a work that has been modified or installed by the recipient, or for 332 | the User Product in which it has been modified or installed. Access to a 333 | network may be denied when the modification itself materially and 334 | adversely affects the operation of the network or violates the rules and 335 | protocols for communication across the network. 336 | 337 | Corresponding Source conveyed, and Installation Information provided, 338 | in accord with this section must be in a format that is publicly 339 | documented (and with an implementation available to the public in 340 | source code form), and must require no special password or key for 341 | unpacking, reading or copying. 342 | 343 | 7. Additional Terms. 344 | 345 | "Additional permissions" are terms that supplement the terms of this 346 | License by making exceptions from one or more of its conditions. 347 | Additional permissions that are applicable to the entire Program shall 348 | be treated as though they were included in this License, to the extent 349 | that they are valid under applicable law. If additional permissions 350 | apply only to part of the Program, that part may be used separately 351 | under those permissions, but the entire Program remains governed by 352 | this License without regard to the additional permissions. 353 | 354 | When you convey a copy of a covered work, you may at your option 355 | remove any additional permissions from that copy, or from any part of 356 | it. (Additional permissions may be written to require their own 357 | removal in certain cases when you modify the work.) You may place 358 | additional permissions on material, added by you to a covered work, 359 | for which you have or can give appropriate copyright permission. 360 | 361 | Notwithstanding any other provision of this License, for material you 362 | add to a covered work, you may (if authorized by the copyright holders of 363 | that material) supplement the terms of this License with terms: 364 | 365 | a) Disclaiming warranty or limiting liability differently from the 366 | terms of sections 15 and 16 of this License; or 367 | 368 | b) Requiring preservation of specified reasonable legal notices or 369 | author attributions in that material or in the Appropriate Legal 370 | Notices displayed by works containing it; or 371 | 372 | c) Prohibiting misrepresentation of the origin of that material, or 373 | requiring that modified versions of such material be marked in 374 | reasonable ways as different from the original version; or 375 | 376 | d) Limiting the use for publicity purposes of names of licensors or 377 | authors of the material; or 378 | 379 | e) Declining to grant rights under trademark law for use of some 380 | trade names, trademarks, or service marks; or 381 | 382 | f) Requiring indemnification of licensors and authors of that 383 | material by anyone who conveys the material (or modified versions of 384 | it) with contractual assumptions of liability to the recipient, for 385 | any liability that these contractual assumptions directly impose on 386 | those licensors and authors. 387 | 388 | All other non-permissive additional terms are considered "further 389 | restrictions" within the meaning of section 10. If the Program as you 390 | received it, or any part of it, contains a notice stating that it is 391 | governed by this License along with a term that is a further 392 | restriction, you may remove that term. If a license document contains 393 | a further restriction but permits relicensing or conveying under this 394 | License, you may add to a covered work material governed by the terms 395 | of that license document, provided that the further restriction does 396 | not survive such relicensing or conveying. 397 | 398 | If you add terms to a covered work in accord with this section, you 399 | must place, in the relevant source files, a statement of the 400 | additional terms that apply to those files, or a notice indicating 401 | where to find the applicable terms. 402 | 403 | Additional terms, permissive or non-permissive, may be stated in the 404 | form of a separately written license, or stated as exceptions; 405 | the above requirements apply either way. 406 | 407 | 8. Termination. 408 | 409 | You may not propagate or modify a covered work except as expressly 410 | provided under this License. Any attempt otherwise to propagate or 411 | modify it is void, and will automatically terminate your rights under 412 | this License (including any patent licenses granted under the third 413 | paragraph of section 11). 414 | 415 | However, if you cease all violation of this License, then your 416 | license from a particular copyright holder is reinstated (a) 417 | provisionally, unless and until the copyright holder explicitly and 418 | finally terminates your license, and (b) permanently, if the copyright 419 | holder fails to notify you of the violation by some reasonable means 420 | prior to 60 days after the cessation. 421 | 422 | Moreover, your license from a particular copyright holder is 423 | reinstated permanently if the copyright holder notifies you of the 424 | violation by some reasonable means, this is the first time you have 425 | received notice of violation of this License (for any work) from that 426 | copyright holder, and you cure the violation prior to 30 days after 427 | your receipt of the notice. 428 | 429 | Termination of your rights under this section does not terminate the 430 | licenses of parties who have received copies or rights from you under 431 | this License. If your rights have been terminated and not permanently 432 | reinstated, you do not qualify to receive new licenses for the same 433 | material under section 10. 434 | 435 | 9. Acceptance Not Required for Having Copies. 436 | 437 | You are not required to accept this License in order to receive or 438 | run a copy of the Program. Ancillary propagation of a covered work 439 | occurring solely as a consequence of using peer-to-peer transmission 440 | to receive a copy likewise does not require acceptance. However, 441 | nothing other than this License grants you permission to propagate or 442 | modify any covered work. These actions infringe copyright if you do 443 | not accept this License. Therefore, by modifying or propagating a 444 | covered work, you indicate your acceptance of this License to do so. 445 | 446 | 10. Automatic Licensing of Downstream Recipients. 447 | 448 | Each time you convey a covered work, the recipient automatically 449 | receives a license from the original licensors, to run, modify and 450 | propagate that work, subject to this License. You are not responsible 451 | for enforcing compliance by third parties with this License. 452 | 453 | An "entity transaction" is a transaction transferring control of an 454 | organization, or substantially all assets of one, or subdividing an 455 | organization, or merging organizations. If propagation of a covered 456 | work results from an entity transaction, each party to that 457 | transaction who receives a copy of the work also receives whatever 458 | licenses to the work the party's predecessor in interest had or could 459 | give under the previous paragraph, plus a right to possession of the 460 | Corresponding Source of the work from the predecessor in interest, if 461 | the predecessor has it or can get it with reasonable efforts. 462 | 463 | You may not impose any further restrictions on the exercise of the 464 | rights granted or affirmed under this License. For example, you may 465 | not impose a license fee, royalty, or other charge for exercise of 466 | rights granted under this License, and you may not initiate litigation 467 | (including a cross-claim or counterclaim in a lawsuit) alleging that 468 | any patent claim is infringed by making, using, selling, offering for 469 | sale, or importing the Program or any portion of it. 470 | 471 | 11. Patents. 472 | 473 | A "contributor" is a copyright holder who authorizes use under this 474 | License of the Program or a work on which the Program is based. The 475 | work thus licensed is called the contributor's "contributor version". 476 | 477 | A contributor's "essential patent claims" are all patent claims 478 | owned or controlled by the contributor, whether already acquired or 479 | hereafter acquired, that would be infringed by some manner, permitted 480 | by this License, of making, using, or selling its contributor version, 481 | but do not include claims that would be infringed only as a 482 | consequence of further modification of the contributor version. For 483 | purposes of this definition, "control" includes the right to grant 484 | patent sublicenses in a manner consistent with the requirements of 485 | this License. 486 | 487 | Each contributor grants you a non-exclusive, worldwide, royalty-free 488 | patent license under the contributor's essential patent claims, to 489 | make, use, sell, offer for sale, import and otherwise run, modify and 490 | propagate the contents of its contributor version. 491 | 492 | In the following three paragraphs, a "patent license" is any express 493 | agreement or commitment, however denominated, not to enforce a patent 494 | (such as an express permission to practice a patent or covenant not to 495 | sue for patent infringement). To "grant" such a patent license to a 496 | party means to make such an agreement or commitment not to enforce a 497 | patent against the party. 498 | 499 | If you convey a covered work, knowingly relying on a patent license, 500 | and the Corresponding Source of the work is not available for anyone 501 | to copy, free of charge and under the terms of this License, through a 502 | publicly available network server or other readily accessible means, 503 | then you must either (1) cause the Corresponding Source to be so 504 | available, or (2) arrange to deprive yourself of the benefit of the 505 | patent license for this particular work, or (3) arrange, in a manner 506 | consistent with the requirements of this License, to extend the patent 507 | license to downstream recipients. "Knowingly relying" means you have 508 | actual knowledge that, but for the patent license, your conveying the 509 | covered work in a country, or your recipient's use of the covered work 510 | in a country, would infringe one or more identifiable patents in that 511 | country that you have reason to believe are valid. 512 | 513 | If, pursuant to or in connection with a single transaction or 514 | arrangement, you convey, or propagate by procuring conveyance of, a 515 | covered work, and grant a patent license to some of the parties 516 | receiving the covered work authorizing them to use, propagate, modify 517 | or convey a specific copy of the covered work, then the patent license 518 | you grant is automatically extended to all recipients of the covered 519 | work and works based on it. 520 | 521 | A patent license is "discriminatory" if it does not include within 522 | the scope of its coverage, prohibits the exercise of, or is 523 | conditioned on the non-exercise of one or more of the rights that are 524 | specifically granted under this License. You may not convey a covered 525 | work if you are a party to an arrangement with a third party that is 526 | in the business of distributing software, under which you make payment 527 | to the third party based on the extent of your activity of conveying 528 | the work, and under which the third party grants, to any of the 529 | parties who would receive the covered work from you, a discriminatory 530 | patent license (a) in connection with copies of the covered work 531 | conveyed by you (or copies made from those copies), or (b) primarily 532 | for and in connection with specific products or compilations that 533 | contain the covered work, unless you entered into that arrangement, 534 | or that patent license was granted, prior to 28 March 2007. 535 | 536 | Nothing in this License shall be construed as excluding or limiting 537 | any implied license or other defenses to infringement that may 538 | otherwise be available to you under applicable patent law. 539 | 540 | 12. No Surrender of Others' Freedom. 541 | 542 | If conditions are imposed on you (whether by court order, agreement or 543 | otherwise) that contradict the conditions of this License, they do not 544 | excuse you from the conditions of this License. If you cannot convey a 545 | covered work so as to satisfy simultaneously your obligations under this 546 | License and any other pertinent obligations, then as a consequence you may 547 | not convey it at all. For example, if you agree to terms that obligate you 548 | to collect a royalty for further conveying from those to whom you convey 549 | the Program, the only way you could satisfy both those terms and this 550 | License would be to refrain entirely from conveying the Program. 551 | 552 | 13. Use with the GNU Affero General Public License. 553 | 554 | Notwithstanding any other provision of this License, you have 555 | permission to link or combine any covered work with a work licensed 556 | under version 3 of the GNU Affero General Public License into a single 557 | combined work, and to convey the resulting work. The terms of this 558 | License will continue to apply to the part which is the covered work, 559 | but the special requirements of the GNU Affero General Public License, 560 | section 13, concerning interaction through a network will apply to the 561 | combination as such. 562 | 563 | 14. Revised Versions of this License. 564 | 565 | The Free Software Foundation may publish revised and/or new versions of 566 | the GNU General Public License from time to time. Such new versions will 567 | be similar in spirit to the present version, but may differ in detail to 568 | address new problems or concerns. 569 | 570 | Each version is given a distinguishing version number. If the 571 | Program specifies that a certain numbered version of the GNU General 572 | Public License "or any later version" applies to it, you have the 573 | option of following the terms and conditions either of that numbered 574 | version or of any later version published by the Free Software 575 | Foundation. If the Program does not specify a version number of the 576 | GNU General Public License, you may choose any version ever published 577 | by the Free Software Foundation. 578 | 579 | If the Program specifies that a proxy can decide which future 580 | versions of the GNU General Public License can be used, that proxy's 581 | public statement of acceptance of a version permanently authorizes you 582 | to choose that version for the Program. 583 | 584 | Later license versions may give you additional or different 585 | permissions. However, no additional obligations are imposed on any 586 | author or copyright holder as a result of your choosing to follow a 587 | later version. 588 | 589 | 15. Disclaimer of Warranty. 590 | 591 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 592 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 593 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 594 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 595 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 596 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 597 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 598 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 599 | 600 | 16. Limitation of Liability. 601 | 602 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 603 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 604 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 605 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 606 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 607 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 608 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 609 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 610 | SUCH DAMAGES. 611 | 612 | 17. Interpretation of Sections 15 and 16. 613 | 614 | If the disclaimer of warranty and limitation of liability provided 615 | above cannot be given local legal effect according to their terms, 616 | reviewing courts shall apply local law that most closely approximates 617 | an absolute waiver of all civil liability in connection with the 618 | Program, unless a warranty or assumption of liability accompanies a 619 | copy of the Program in return for a fee. 620 | 621 | END OF TERMS AND CONDITIONS 622 | 623 | How to Apply These Terms to Your New Programs 624 | 625 | If you develop a new program, and you want it to be of the greatest 626 | possible use to the public, the best way to achieve this is to make it 627 | free software which everyone can redistribute and change under these terms. 628 | 629 | To do so, attach the following notices to the program. It is safest 630 | to attach them to the start of each source file to most effectively 631 | state the exclusion of warranty; and each file should have at least 632 | the "copyright" line and a pointer to where the full notice is found. 633 | 634 | 635 | Copyright (C) 636 | 637 | This program is free software: you can redistribute it and/or modify 638 | it under the terms of the GNU General Public License as published by 639 | the Free Software Foundation, either version 3 of the License, or 640 | (at your option) any later version. 641 | 642 | This program is distributed in the hope that it will be useful, 643 | but WITHOUT ANY WARRANTY; without even the implied warranty of 644 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 645 | GNU General Public License for more details. 646 | 647 | You should have received a copy of the GNU General Public License 648 | along with this program. If not, see . 649 | 650 | Also add information on how to contact you by electronic and paper mail. 651 | 652 | If the program does terminal interaction, make it output a short 653 | notice like this when it starts in an interactive mode: 654 | 655 | Copyright (C) 656 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 657 | This is free software, and you are welcome to redistribute it 658 | under certain conditions; type `show c' for details. 659 | 660 | The hypothetical commands `show w' and `show c' should show the appropriate 661 | parts of the General Public License. Of course, your program's commands 662 | might be different; for a GUI interface, you would use an "about box". 663 | 664 | You should also get your employer (if you work as a programmer) or school, 665 | if any, to sign a "copyright disclaimer" for the program, if necessary. 666 | For more information on this, and how to apply and follow the GNU GPL, see 667 | . 668 | 669 | The GNU General Public License does not permit incorporating your program 670 | into proprietary programs. If your program is a subroutine library, you 671 | may consider it more useful to permit linking proprietary applications with 672 | the library. If this is what you want to do, use the GNU Lesser General 673 | Public License instead of this License. But first, please read 674 | . 675 | --------------------------------------------------------------------------------
