| 1）LCD屏幕显示颜色 3 | 2）LCD屏幕显示图片 4 | 5 | 一、LCD屏幕显示颜色 6 | 1）预习open、close、read函数的使用。 7 | 练习4： 8 | 1）编辑open.c源程序，保存共享文件夹中。实现如下功能：（open、close） 9 | 打开/home/gec/Desktop/1.txt文件，打印open函数的返回值，关闭文件。 10 | 2）使用vi/vim编辑器写“hello world!”字符串到1.txt文件中。read.c源程序实现如下功能：（read、bzero） 11 | 读取1.txt文件中“hello world!”字符串到数组txt_buf中，并打印txt_buf中的内容。 12 | 2）mmap、munmap 13 | 14 | read.c---->000-张三-李四(4).c 15 | 16 | man手册

1）BMP文件存储数据时，图像的扫描方式是按从左到右、从下到上的顺序。 124 | LCD屏幕显示数据时，图像的扫描方式是按从左到右、从上到下的顺序。 125 | 问题1： 126 | 颠倒图片 127 | 128 | 2）BMP文件由文件头、位图信息头、颜色信息和图形数据四部分组成。 129 | BMP文件头（14byte）数据结构含有BMP文件的类型、文件大小和位图起始位置等信息。 130 | 位图信息头（40byte）说明位图的尺寸等信息。 131 | 7) 19-22：位图宽度，以像素为单位。8000 0000，为00000080h=128。 132 | 　　 8）23-26：位图高度，以像素为单位。9000 0000，为00000090h=144。 133 | 134 | 颜色信息和图形数据 --->颜色数据。 135 | typedef struct tagRGBQUAD { 136 | 　　BYTE rgbBlue;// 蓝色的亮度（值范围为0-255) 137 | 　　BYTE rgbGreen; // 绿色的亮度（值范围为0-255) 138 | 　　BYTE rgbRed; // 红色的亮度（值范围为0-255) 139 | 　　BYTE rgbReserved;// 保留，必须为0 140 | 　} RGBQUAD; 141 | 142 | 当biBitCount=24时，1个BMP像素占3个字节； 143 | LCD屏幕1个像素点4byte 144 | 问题2： 145 | 800*480个BMP像素点变成800*480个LCD像素点。 146 | 147 | 一张24bitBMP格式图片的大小 = 尺寸* 每个像素点占用的空间大小 + 54byte 148 | main.bmp = 800*480*3byte + 54byte 149 | =1152054byte 150 | 举例： 151 | 显示800*480尺寸的24bitBMP格式图片到LCD屏幕上。 152 | 编程思路： 153 | 1）打开LCD屏幕，打开图片。 154 | 2）创建映射通道，将内存中图片的颜色数据通过p_mmap放到LCD屏幕。 155 | 1）去掉BMP图片的前54byte。 156 | 2）解决两个算法： 157 | 1）800*480个BMP像素点变成800*480个LCD像素点。 158 | char bmp_buf[800*480*3]; //char --->1byte 159 | int lcd_buf[800*480]; //int --->4byte 160 | 161 | read读取main.bmp中图像数据到bmp_buf。 162 | 163 | 164 | 2）颠倒图片。 165 | 3）关闭LCD屏幕，关闭图片，释放映射空间的资源。 166 | 167 | 使用U盘挂载的方式将图片放到开发板/root/project/images 168 | 1）U盘文件系统一定是FAT32/FAT格式 169 | 2）挂在U盘，SercureCRT出现：sda: sda1，挂载成功。（/mnt/udisk/） 170 | [root@GEC6818 /]#cd /mnt/udisk/

-------------------------------------------------------------------------------- /Day4/note.txt: -------------------------------------------------------------------------------- 1 | 20190704主要讲解知识点： 2 | 1）实时时间的显示。 3 | 2）摄像头的移植。 4 | 5 | 6 | 7 | 8 | 9 | 10 | 一、实时时间的显示 11 | 1）查看系统时间date 12 | 2）通过终端命令修改时间。 13 | 年月日： date -s 2019-7-4 14 | 时分秒： date -s 09:13:30 15 | 3）使用函数进行时间的设置。 16 | system 17 | 功能：执行终端的shell命令。 18 | #include 19 | int system(const char *command); 20 | const char *command：终端的shell命令。 21 | 22 | system("date -s 2019-7-4"); 23 | system("date -s 09:13:30"); 24 | 25 | 4）time、ctime 26 | man -f time 27 | man -f ctime 28 | 29 | man 3 time 30 | 31 | 1）Notpad++：进行C语言源程序的编辑。 32 | 2）SercureCRT：进行GEC6818开发板的控制及程序的下载。 33 | 3）VMware-Workstation10：实现Windows系统和Linux系统双个系统的运行。 34 | 4）Ubuntu12.04：视频监控系统开发的系统平台。 35 | time - get time 36 | #include 37 | time_t time(time_t *tloc); 38 | time_t *tloc：存储获取到的时间的地址。 39 | 返回值：成功：获取到的时间。 40 | 41 | ctime 42 | man 3 ctime 43 | 功能：将time函数获取到的十进制的时间转化成字符串。 44 | #include 45 | char *ctime(const time_t *timep); 46 | const time_t *timep：存储十进制的时间地址。 47 | 返回值：成功 返回转化后的时间字符串 48 | 49 | //"Wed Jul 3 18:39:17 PDT 2019" 50 | 系统要求时间显示格式： 51 | 09:41:50 52 | 2019-7-4 53 | 54 | 思路：对"Wed Jul 3 18:39:17 PDT 2019"字符串进行切割与组合。 55 | 切割：strtok 56 | 组合: sprintf 57 | 58 | man -f strtok 59 | #include 60 | char *strtok(char *str, const char *delim); 61 | char *str：要切割的字符串的地址。 62 | const char *delim：切割的方式（' '、'-'、'\'、':'……） 63 | 返回值：成功 放回切割后的字符串。 64 | 65 | sprintf 66 | #include 67 | int sprintf(char *str, const char *format, const char *format); 68 | char *str：拼接后新的字符串存储的地址。 69 | const char *format：拼接的字符串1. 70 | const char *format：拼接的字符串2. 71 | 72 | 4）使用字库显示时间到LCD屏幕上。 73 | 举例：参考font文件夹中的程序 74 | arm-linux-gcc main.c -o armmain -L./ -lfont 75 | 76 | 在Linux系统中有静态库(.a)和动态库(.so) 77 | libfont.a --->静态库 78 | 库的命名规则：前缀+库名称+后缀 79 | 前缀：lib 80 | 库名称:font 81 | 后缀：.a 82 | 83 | 练习10： 84 | 实时显示时间在LCD屏幕上。 85 | 10:49:51 86 | 2019-7-4 87 | 88 | 二、头文件的制作。 89 | 函数的定义、调用及声明。 90 | 1）创建一个main.c程序，将具体某一个功能进行函数封装。 91 | 2）分别在创建两个文件。（同名不同格式的文件.c/.h） 92 | 3）将函数的定义放到.c文件中，将函数的声明和函数用到的头文件放到.h文件中。 93 | 94 | 注意：编译时需要一起编译所有.c文件。 95 | 96 | 练习11： 97 | 根据bmp文件夹制作touch_screen.h和touch_screen.c的头文件，在main.c文件中调用，实现坐标的连续获取。 98 | 99 | 三、摄像头的移植。 100 | 1）查看摄像头的设备文件。 101 | 1）不插摄像头，切换路径到/dev/目录中 102 | cd /dev/ 103 | ls 104 | 105 | video0 106 | video1 107 | video2 108 | video3 109 | video4 110 | video5 111 | video6 112 | 2）插摄像头，切换路径到/dev/目录中 113 | video0 114 | video1 115 | video2 116 | video3 117 | video4 118 | video5 119 | video6 120 | video7 121 | 通过比较确认设备文件路径:/dev/video7 122 | 3） 更改camera.c中的设备路径。 123 | 4）编译程序。 124 | arm-linux-gcc *.c -o armmain -I./jpeg -L./jpeg -ljpeg -lapi_v4l2_arm -pthread 125 | 5）用U盘下载libapi_v4l2_arm.so、libjpeg.so、 libjpeg.so.8.3.0到/root/project/lib 126 | 6）复制libapi_v4l2_arm.so、libjpeg.so、 libjpeg.so.8.3.0到/lib/ 127 | 128 | 四、整体系统的优化与移植 129 | 用到的库 130 | libfont.a 131 | libapi_v4l2_arm.so 132 | libjpeg.so 133 | 总的编译命令： 134 | arm-linux-gcc *.c -o armmain -I./jpeg -L./jpeg -ljpeg -lapi_v4l2_arm -L./ -lfont -pthread 135 | 136 | 最好建一个文件夹project_v1 137 | project_v2 138 | …… 139 | 140 | 141 | 142 |
