不同版本S5PV210 wince6.0 BSP I2C 驱动居然会有差异？老的IIC 驱动容易出问题？

悲催了。难道又要换整个BSP啊。汗！

正常来说是这样才行的。
[WAV] OpenI2C() ----------------------------------------
[WAV] I2C OPEN : I2C0: SUCCESS
[WAV] ACTUAL I2C CLCOK SPEAD : 64 Khz
[WAV] Init is successful

换一个新的版本BSP IIC驱动到老的BSP上试试。

换了新BSP 版本的IIC驱动，还是一样，看来是某个细节没处理好，再看看。

搞定了，使能一个电源IO，没上拉，居然就导致驱动能力不足，导致设备的电源达不到工作状态，搞定了。
不过我以前在新的BSP上也没上拉啊，咋回事呢？坑爹哦
