摄像头采集问题

cjinxing

我是个菜鸟，图像搞了很久都搞不出来，求助各位大哥！！
这是我根据上位机通信协议写的采集程序，但是什么都看不到，麻烦大家帮我看看。

下面是通信协议上位机（PC机）
点击“采集图像”按钮后，将通过串口发送一个字符‘s’给下位机，表示采集图像开始。
下位机（单片机）
下位机通过串口收到采集图像命令后，先返回应答信号，应答信号为两个字节，分别为16进制的0x55,0xAA。
接着发送图像的宽度值W和高度值H，各占三个字节，比如宽度W为40，高度H为30，则发送字符串‘040030’。又如宽度W为320，高度H为240，则发送字符串‘320240’。
接下来按顺序发送W*H个图像像素点的灰度值，每个灰度值为一个字节（数值大小范围0-255）。
