[讨论] 关于 ov2640

HI, ALL: 小弟正在弄wince下的ov2640, 希望有经验的牛哥们给多多帮助. 我看了这个论坛的所有OV2640的问题.应该有几位牛哥把OV2640弄得差不多了. 希望已经做OK的牛哥们把详细的流程贴出来分享下.  ( OV的那个DATASHEET确实太简单了,很多REGISTER 都是RESERVE, 太坏了) 这样, 后来人就有个方向了. 我正在做WINCE下的OV2640, 目前只是透过I2C读到了2640 ID;我目前的REGISTER是这样的, (我是用2630的代码去初始化2640的, 可能有问题) ; 对了,我的MSN是:davidpeng983@hotmail.com, 我专门做WINCE500下的驱动开发的; 哪位牛哥分享下经验,不胜感谢了!!!

您好:

小弟之前有发一份帖子,是关于 OV2640 的 I2C 无法读取的问题,我也是用OV2630 的源码去调试 OV2640 ,怪的是 2630 可以读取 I2C 的资料,但2640 却无法读取 I2C 的资料(如 ProdID => 0X0A),不知大侠是否直接以程序就可以正确读取资料,亦还是必须调整 MCLOCK 的 Freq(24M),或Pull down/up #RESET 和 #PWDN 的硬件 PIN 脚,以达到 OV2640 初始化的要求
? 谢谢!!

OV的2640有几个版本,现在好像已经到了2640R4了,就是用2640的不同版本的参数都一定能共用何况2630???? 其实一般来说版本不同关键的就是Reset和Pwdn脚变了,看对应的规格书对比一下。而且2640通过0XFF来判断你要使用的是那里的储存器(有DSP 和Sensor两种)。


没有初始化参数找OV要就是了!

最近在开始配置OV2640,但是出来的图像极正常,暗处一片绿,亮处桃红。

能否将你的寄存器配置文件发给我一份?
