前一段时间随便买的一个OV2640,回来调试发现电平都是1.3V,用3.3的单片机没办法调试。后来又买了ALIENTEK的摄像头,也买了块STM32F407的开发板。
把原子哥的代码改了简单的改了一下,去掉的LCD的相关代码,其它完全相同。
现在做320*240的图片拍摄,数据帧不正常,特别是头,头部老有0,而且也没找到JPEG的头D8.
尾部有很多0,但是可以看到FF D9结束符
JPEG的输出模式,我把jpeg_data_ok放到if里面去了,个人觉得放到里面是对的,放到外面也没输出了。
其它地方完全没改了。
跪求高手看看问题在哪?
这里应该是有一些数据是正常的,但是每次头数据都不正常。
我就是配置的问题 用这个配置就可以有图片了 你试试
