关于wince5的OV9650驱动问题 [复制链接]

驱动camera.dll都正常加载。
串口打印
CAMERA: CIS_Open
CIS: IOCTL_POWER_CAPABILITIES
CAMERA: CIS_Open
CAMERA: CIS_Close

也就是CIS_Open函数加载了，但是CIS_Init()函数没有加载，请问是为什么，找不到哪里调用的。

自己顶一下

“CAMERA: CIS_Open”？没有加载就直接open？哪里调用这个open的？
看看Init里面是不是有错误导致加载失败的。

楼主 使用软件看看到底是否加载了，还是你看错了。哈哈

谢谢楼上，是看错了，是i2c驱动忘记加载，但是加载后又发现新问题

进行到这里就停止了，无法再进行了，BSP也无法启动了，还没找到为什么？

这么一大串ACK未收到，结果还OK？检查一下驱动吧。

IIC驱动有问题。

IIC需要硬件上拉的。

注册表这样对不对呢？
