摄像头驱动是坛子上广为流传的王大哥的程序！我的方案是OV7670+FIFO+MSP430摄像头始时钟为24M，单片机时钟为8M!
悲剧的就是出图很诡异！我的程序：

你买的谁的模块？？图片呢，卖家没给你配置参数吗？？？

gloryzkl

买的浙江一家的，给的还是你的程序,也只给了程序！

刚有调试了一下，图出来了，但是很模糊！

LZ你好   我的问题跟你差不多  我也是OV7670+FIFO  然后串口给上位机  上位机软件跟你是一样的  但是我的图像是这样的

(原文件名:QQ截图20120218213650.png)

while(1!= wrOV7670Reg(0x12, 0x10));   //QVGA   YUV
//  wrOV7670Reg(0x40, 0xd0);     
    wrOV7670Reg(0x17, 0x16);   
    wrOV7670Reg(0x18, 0x04);

    wrOV7670Reg(0x73, 0x00);
    wrOV7670Reg(0xA2, 0x02);   


wrOV7670Reg(0x3a, 0x00);  
wrOV7670Reg(0x0c, 0x0c);    这是我的寄存器配置  我是要灰度图像  所以选择YUV格式  接收时只要前八位  分辨率160X120不知道对不对？？  求指点？？

王老师，我是用msp430+ov7670+fifo调试，彩带测试出现下面的结果，能看出是彩带来，但是都错位了，请问这问题应该是那部分的错误？
