dsp5509处理ov7670采集到的图像tft显示异常什么情况？

碳酸钙

显示彩条的时候也异常，白色完了就是红色，谁给分析下什么原因

正点原子

数据有干扰，先解决干扰问题，杜邦线连接的？

---------------------------------
杜邦线连接的。我按着你的方法把数据线绑一起，其他的线绑一起也是这样。用彩带测试的时候彩带颜色不是渐变的，每条彩带之间有杂色。。。还有显示分成三块是什么原因

回复【3楼】碳酸钙:
---------------------------------
得慢慢调试了

碳酸钙

c彩条测试这样了，颜色顺序不对

4楼的图是彩条测试的现象，求指导调试方向

回复【6楼】碳酸钙:
---------------------------------
出来图像呢，不是楼主位的图像吧？

碳酸钙

原子哥，现在显示的情况就是这样，是不合适寄存器设置的有问题呢

原子哥7楼的图是我现在的现实情况，是不是寄存器设置的有问题？
