dsp5509处理ov7670采集图像tft显示异常

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

得慢慢调试了

c彩条测试这样了，颜色顺序不对

回复【4楼】发烧友:
---------------------------
4楼的图是彩条测试的现象，求指导调试方向

出来图像呢，不是楼主位的图像吧？

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？

就是把0x71 设置为0x80，显示的彩条对应的颜色不对

没遇到过了。你这彩条看似正常， 出来的图像这般摸样...
