42 | int k ; 43 | k = 0 ; 44 | for (y = 0; y < 60; y++) { 45 | for (x = 0; x < 108; x++){ 46 | // 在(x*10,y*13)至(x*10+10,y*13+13)这片区域填充RGB值bmp[k] 47 | print_image(x*10,y*13,x*10+10,y*13+13,bmp[k]); 48 | k++; 49 | } 50 | } 51 | } 52 | ``` 53 | 54 | 在虚拟机中效果如下。 55 | 56 | ![img](https://github.com/CasterWx/AntzOS/raw/master/screen/my.gif) 57 | 58 | ## 二. 双线性插值 59 | 60 | 在使用第一种粗略暴力的方式实现启动动画之后，第二天的数字图像处理课程中，听到老师讲matlab中的图片放大缩小函数的原理，了解了`双线性插值`这个算法，于是想到用这个方法来重新实现启动界面。 61 | 62 | 双线性插值的基本原理是，假设源图像大小为MxN，目标图像为AxB。那么两幅图像的边长比分别为：M/A和N/B。这两个比例值一般是浮点数。目标图像的第（i,j）个像素点（i行j列）可以通过边长比对应回源图像。其对应坐标为（i*m/a,j*n/b）。显然，这个对应坐标一般来说不是整数，而非整数的坐标是无法在图像这种离散数据上使用的。双线性插值通过寻找距离这个对应坐标最近的四个像素点，来计算该点的值（灰度值或者RGB值）。 63 | 64 | 其实可以理解为通过其周围的四个点，`中和`出这片区域中的其他点。 65 | 66 | ![2123](https://www.cnblogs.com/images/cnblogs_com/LexMoon/1246510/o_213123.png) 67 | 68 | ![s](../sreen/1.png) 69 | 70 | 我们想得到一张放大的图片，现在有`原图像`和`目标图像`。那么，有一个最基本的问题摆在我们面前：是遍历`原图像`呢，还是遍历`目标图像`呢？ 71 | 72 | 在实践的过程中，通常都是遍历`目标图像`的。因为这样可以确保`目标图像`的每一个像素都是有值的。 73 | 74 | 就拿上图的例子来说，右图`目标图像`中的 [0,0] 点很顺利的找到了左图`原图像`中与自己对应的 [0,0] 点。然后 [0,1] 点就懵逼了，它应该找 [0,0.33]点吗？没有这个点啊。 75 | 76 | 插值这个方法，就是为了解决这个问题的。 77 | -------------------------------------------------------------------------------- /Makefile: -------------------------------------------------------------------------------- 1 | INCPATH = include/ 2 | MAKE = make.exe 3 | COPY = copy 4 | DEL = del 5 | TREE = tree /f 6 | Antz_kernel = main/bootpack.obj asmfunc/naskfunc.obj assic/char.set windows/graphic.obj lgdt/set_lgdt.obj interrupt/int.obj io/fifo.obj thun/keychar.obj thun/thun.obj task/timer.obj 7 | 8 | default : 9 | $(MAKE) img 10 | 11 | # 需要的 12 | mbr.bin : boot/mbr.asm Makefile 13 | nask.exe boot/mbr.asm mbr.bin mbr.lst 14 | 15 | asmhead.bin : boot/asmhead.asm Makefile 16 | nask.exe boot/asmhead.asm asmhead.bin asmhead.lst 17 | 18 | # naskfunc.obj会放在asmfunc目录中，如果在bootpack.bim合成时候不到，not find naskfunc会报错一万次！！！2018年9月9日15:46:27 19 | naskfunc.obj : asmfunc/naskfunc.nas Makefile 20 | nask.exe asmfunc/naskfunc.nas asmfunc/naskfunc.obj asmfunc/naskfunc.lst 21 | 22 | %.gas : %.c Makefile 23 | cc1.exe -I include/ -Os -Wall -quiet -o $*.gas $*.c 24 | 25 | %.nas : %.gas Makefile 26 | gas2nask.exe -a $*.gas $*.nas 27 | 28 | %.obj : %.nas Makefile 29 | nask.exe $*.nas $*.obj $*.lst 30 | 31 | bootpack.bim : $(Antz_kernel) Makefile 32 | obj2bim.exe @include/haribote.rul out:bootpack.bim stack:31360k map:bootpack.map $(Antz_kernel) 33 | 34 | bootpack.hrb : bootpack.bim Makefile 35 | bim2hrb.exe bootpack.bim bootpack.hrb 0 36 | 37 | antz.sys : asmhead.bin bootpack.hrb Makefile 38 | copy /B asmhead.bin+bootpack.hrb antz.sys 39 | 40 | antz.img : mbr.bin antz.sys Makefile 41 | edimg.exe imgin:include/fdimg0at.tek wbinimg src:mbr.bin len:512 from:0 to:0 copy from:antz.sys to:@: imgout:antz.img 42 | 43 | # 指令 44 | img : 45 | $(MAKE) antz.img 46 | 47 | run : 48 | $(MAKE) img 49 | $(MAKE) clean 50 | 51 | clean : 52 | -$(DEL) *.bin 53 | -$(DEL) *.lst 54 | 55 | -$(DEL) asmfunc\naskfunc.lst 56 | -$(DEL) asmfunc\naskfunc.obj 57 | 58 | -$(DEL) interrupt\int.lst 59 | -$(DEL) interrupt\int.obj 60 | 61 | -$(DEL) io\fifo.lst 62 | -$(DEL) io\fifo.obj 63 | 64 | -$(DEL) lgdt\set_lgdt.lst 65 | -$(DEL) lgdt\set_lgdt.obj 66 | 67 | -$(DEL) main\bootpack.lst 68 | -$(DEL) main\bootpack.obj 69 | 70 | -$(DEL) windows\graphic.lst 71 | -$(DEL) windows\graphic.obj 72 | 73 | -$(DEL) thun\thun.lst 74 | -$(DEL) thun\thun.obj 75 | 76 | -$(DEL) thun\keychar.lst 77 | -$(DEL) thun\keychar.obj 78 | 79 | -$(DEL) task\timer.lst 80 | -$(DEL) task\timer.obj 81 | 82 | -$(DEL) bootpack.map 83 | -$(DEL) bootpack.bim 84 | -$(DEL) bootpack.hrb 85 | -$(DEL) antz.sys 86 | 87 | tree : 88 | $(TREE) 89 | -------------------------------------------------------------------------------- /OS-Build/Lock.md: -------------------------------------------------------------------------------- 1 | ## 锁 2 | 3 | #### 信号量与锁的实现思想 4 | 5 | > sync.h 6 | ```c 7 | // 信号量 8 | struct semaphore { 9 | uint value ;

34 | io_sti(); 35 | // i 就是中断返回的值，分析他即可得到按键信息, 在下面我把它转换为了16进制存储在了一个char array s中 36 | sprintf(s, "%02X", i); 37 | // 把两次中断变为一次，看下文 38 | } 39 | ``` 40 | #### 得到了s，就是得到了键盘按键的信息。 41 | 42 | #### 开头说了，按下一次，会有两次中断发生，那么我们是否可以使用一个flag来区分按下和弹起呢？ 43 | 44 | ``` 45 | if (flag){ 46 | keyshow(); // 显示这次按键，把按下的中断当作一个键位的信息，把弹起的中断用下面flag的方法屏蔽掉 47 | } 48 | // 屏蔽 49 | if(flag==1){ 50 | flag = 0 ; 51 | }else { 52 | flag = 1 ; 53 | } 54 | ``` 55 | #### 这是一个很拙略的实现方法，而且我测试了几次之后发现有一个bug，就是同时按下两个键位时，屏蔽的方法就会变成另一种。 56 | #### 比如开始是用按下识别一个键位，那么同时按下两个键位之后就是以弹起的方法来识别键位了。 57 | 58 | #### 这个情况留在之后再考虑。 59 | 60 | ## 二 . 按键识别 61 | 62 | #### 上文中已经将按键返回的数据存储到了char数组s，只需要在屏幕上显示s的数据就可以了。 63 | 64 | ``` 65 | int write_x = 55 ; //按键显示位置的x，y坐标 66 | int write_y = 57 ; 67 | 68 | void key(struct BOOTINFO *binfo,char s[40]){ 69 | //在指定位置显示数据 70 | showkeys(binfo->vram, binfo->scrnx, write_x, write_y, COL8_FFFFFF, s); 71 | // 显示之后光标右移 72 | write_x += 19 ; 73 | // 如果超出右边界，换行 74 | if(write_x>155){ 75 | write_x = 55 ; 76 | write_y += 19 ; 77 | } 78 | // 如果超出下边界，刷新清理本页，开启新的一页 79 | if(write_y>180){ 80 | new_pe(binfo); 81 | } 82 | 83 | } 84 | ``` 85 | ### 结果： 86 | ![print](https://www.cnblogs.com/images/cnblogs_com/LexMoon/1246510/o_print.jpg) 87 | 88 | #### 很明显，我们需要编写一种转换机制，将表示16进制的数据对应成为键盘按键。 89 | 90 | #### 键盘上需要显示的有字母和特殊符号，还有一些功能性的按键shift，backspace等。 91 | 92 | #### 测试记录了几个按键的按下数据 93 | > 键盘 按下 94 | 95 | > F1 3B 96 | 97 | > F2 3C 98 | 99 | > F3 3D 100 | 101 | > F4 3E 102 | 103 | > A 1E 104 | 105 | > B 30 106 | 107 | > Backspace OE 108 | 109 | > 空格 39 110 | 111 | #### 既然已经知道了对应关系，那么很容易就可以建立一种对应。 112 | 113 | #### 先来实现这几个特殊按键功能 114 | 115 | #### 我打算将 F1 实现为 clear 功能，实现页面刷新 。 Backspace 实现回退功能。Enter实现确定以及回车功能。 116 | 117 | #### Clear为了确保安全性，对F1按键的两种中断都会发生响应。 118 | ``` 119 | void showkey(struct BOOTINFO *binfo,char s[40]){ 120 | // 回车键 121 | if(strcmp(s,"1C")==0){ 122 | write_x = 55 ; // 光标移动至下一行起始位置。 123 | write_y += 19 ; 124 | showkeys(binfo->vram, binfo->scrnx, 0, write_y, COL8_FFFFFF, "AntzOS>"); 125 | } 126 | // F1 刷新本页 127 | else if(strcmp(s,"3B")==0){ 128 | new_pe(binfo); 129 | } 130 | // 空格 光标后移一位 131 | else if(strcmp(s,"39")==0){ 132 | showkeys(binfo->vram, binfo->scrnx, write_x, write_y, COL8_FFFFFF, " "); 133 | write_x += 19 ; 134 | } 135 | // Backspace 删除退格 136 | else if(strcmp(s,"0E")==0){ 137 | // 回退 138 | write_x -= 19 ; 139 | //重新覆盖这片区域 140 | area_flash(binfo->vram, binfo->scrnx , COL8_000000, write_x, write_y, write_x+19, write_y+19);

Bug引发的思考 162 | 163 | #### 这里开始就和AntzOs实现没有多少联系了，不过在我测试按键中断时候发现了很多奇怪的小问题。 164 | 165 | > Caps Lock(大小写键) 是否开启并不会影响中断对你一个按键的返回信息，也就是所谓的大小写中断其实是无法区分的，那么现代系统如何区分呢？ 同理于上面我们区分按下和弹起两次中断，我们可以将Caps Lock键的状态获取到，从而对当前按键进行所谓的大小写区分。 166 | 167 | > 按下两次导致规则置换，会不会是因为中断响应的时间导致的。 168 | -------------------------------------------------------------------------------- /load_bmp.md:

16, 287 | 16, 288 | 16, 289 | 16, 290 | 52, 291 | 52 292 | ``` 293 | 因为目前还没有实现磁盘驱动，没有文件系统，我们只能把值硬编码进系统中。 294 | 295 | bmp.h 296 | 297 | ![unsignedchar](https://github.com/CasterWx/AntzOS/blob/master/screen/load_char.png?raw=true) 298 | 299 | 一个数万项的unsigned char数组,再上面程序中我们同样可以得到图片的长宽信息，那么下一步就是在系统中显示图片了。 300 | ```c 301 | #include 302 | 303 | void to_printf_dijkstra(int sx,int sy){ 304 | // sx,sy是屏幕分辨率 305 | int x, y; 306 | int k = 0 ; 307 | for (y = 0; y < 115; y++) { //图片宽100,高115个像素 308 | for (x = 0; x < 100; x++){ 309 | printf_(sx , bmp_b[k] , x+sx-100, y, x+sx-100, y); 310 | k++; 311 | } 312 | } 313 | } 314 | ``` 315 | 只需要在一个命令响应中调用这个函数即可了，这就是效果了(真机测试也是同样)。 316 | 317 | ![效果](https://github.com/CasterWx/AntzOS/blob/master/screen/a.gif?raw=true) 318 | 319 | 不知道你有没有考虑到这个问题，这个115x100的图片有11500个像素点，这是一张很小很小的图片了，如果我们用一张正常一点的尺寸较大的图片，比如500x400，那就是200000个像素点了，这对没有实现磁盘驱动，靠硬编码进系统的antz压力非常大，所以此处加载图片虽然成功了，但实际上还远不能入此，这只是一个思想，当我可以实现硬盘驱动和文件系统之后，我们可以把上面bmp文件的rgb读取的程序直接放在内核中成为API，然后调用起来就方便很多了，对于那种超大图片，可以靠这样实现分步显示。

[Github项目地址](https://github.com/CasterWx/AntzOS) 8 | 9 | ### 在之前的任务中，我们已经通过直接操作显卡驱动完成了简单的图形化。 10 | ### 需要了解之前的部分： 11 | > 直接操作显卡请参考day03 12 | 13 | > 简单图形化的实现请参考day09 14 | 15 | > 键盘按键中断响应请参考day10 16 | 17 | > Makefile 18 | 19 | ### 项目目录 20 | 21 | ![s](https://www.cnblogs.com/images/cnblogs_com/LexMoon/1246510/o_project.jpg) 22 | 23 | ## 一 . 如何实现命令缓存 24 | 25 | ### 在之前已经完成了键盘的响应工作，但这种响应却是有很大的问题，比如说对于一次按键的两次中断处理。后来我把两种中断都加入了响应判断中，这样就不会有之前第10天所提到的bug了。 26 | 27 | ### * 在替换函数中完成识别。修改如下 28 | ``` 29 | char* replace_char(char s[40]){ 30 | char *chr = "$" ; 31 | if((strcmp(s,"1E")==0)||(strcmp(s,"9E")==0)){ 32 | chr = "a" ; 33 | }else if((strcmp(s,"30")==0)||(strcmp(s,"B0")==0)){ 34 | chr = "b" ; 35 | } 36 | ... // 省略 37 | return chr ; 38 | ``` 39 | ### * 这里是一些功能按键的识别修改 40 | ``` 41 | // Enter -> 回车键 响应之前缓存的命令 换行 42 | if((strcmp(s,"1C")==0)||(strcmp(s,"9C")==0)){ 43 | action_command(binfo); //响应命令 44 | write_x = 58 ; //下面是换行 45 | write_y += 19 ; 46 | putfonts8_asc(binfo->vram, binfo->scrnx, 4, write_y, COL8_FFFFFF, "AntzOS>"); 47 | } 48 | // F1 -> 终端刷新 类似于clear命令 49 | else if((strcmp(s,"3B")==0)||(strcmp(s,"BB")==0)){ //关于F1的响应中断 50 | sprintf(command,"%s",""); // 命令缓存清空 51 | flag = 0 ; // 按键模式回复默认，这个看第10天，本质目的是为了处理一次按键的两次终端 52 | new_pe(binfo); // 通过操作显存直接刷新当前终端 53 | putfonts8_asc(binfo->vram, binfo->scrnx, 4, write_y, COL8_FFFFFF, "AntzOS>"); 54 | } 55 | // Backspace -> 删格键 56 | else if(strcmp(s,"0E")==0){ 57 | // 回退 58 | write_x -= 8 ; 59 | boxfill8(binfo->vram, binfo->scrnx , COL8_000000, write_x, write_y, write_x+19, write_y+19); 60 | if(write_x<=58){ 61 | write_x = 146 ; 62 | write_y -= 19 ; 63 | } 64 | } 65 | ``` 66 | ### 这些就是按键识别上目前修改的内容了。 67 | 68 | ### 接下来我们要添加一个功能，在每次按键之后，不但在屏幕上显示这个键，而且将他缓存在缓冲区，在下次回车的时候进行识别，并清空。 69 | 70 | ### 先来看一个简单的demo 71 | 72 | ``` 73 | // command数组就是命令缓存区 74 | char command[100] = ""; 75 | 76 | void add_command(char *s) { 77 | sprintf(command,"%s%s",command,s); 78 | } 79 | 80 | void action_command(){ 81 | // 响应 82 | } 83 | 84 | ``` 85 | 86 | ## 二 . 实现 87 | 88 | ### command就是一个命令缓存数组，每次按键之后调用add_command()命令将这次的按键保存。 89 | 90 | ### sprintf()这个函数是字符串格式化命令，主要功能是把格式化的数据写入某个字符串中。sprintf 是个变参函数。使用sprintf 对于写入buffer的字符数是没有限制的，这就存在了buffer溢出的可能性。 91 | 92 | ### 我们使用sprintf函数直接在command后面添加了s字符。 93 | 94 | ### 那么在下次按下Enter的时候，我们只需要调用action_command,并且在里面识别是什么命令，然后做出合适的响应即可。 95 | 96 | ### 来看看完整的命令缓冲区实现。 97 | 98 | ``` 99 | // 指令缓存，但是因为中断响应的时间问题，终端输入速度要非常慢 100 | char command[100] = ""; 101 | void
