你好,
I use the cyfxusbi2cregmode under INC to operate I2c, which can work normally and catch the correct waveform;However, in other projects, CyCx3UvcAppThread cannot be started by calling CyFxUsbI2cTransfer function I2c. The waveform caught through oscilloscope always catches the waveform initialized by MIPI through I2c (address 0x0E).Anybody can help me?

您好,
CX3的I2C模块会用于内部控制自身的MIPI模块以及外部的sensor。能不能请您用中文解释下 CyCx3UvcAppThread cannot be started by calling CyFxUsbI2cTransfer function I2c.这句话说什么意思?

就是我在CyCx3UvcAppThread这个线程下调用CyFxUsbI2cTransfe来操作其它的slave设备,发现抓不到I2c操作其它设备的波形,地址肯定是对的因为我用别的板子通过I2c来操作可以读写成功。

你用uart打印过CyFxUsbI2cTransfer的返回值是否是success吗?是否有错误代码?
