Hi,all

   Please help me, Thank you very much.

   I connect one CortexM4 board with FXAS21002 and FXOS8700C on FRDM-STBC-AGM01 by I2C, I used the same I2C(Pin: I2C-SCL1/I2C-SDA1).

   I initializad FXAS21002 and FXOS8700C at the same time. I used the yourexample code.

 

Problem 1:

   FXAS21002 reades the value of WHO_AM_I(0x0C) is successful, and FXOS8700C reades the value of WHO_AM_I(0x0D) is successful. then Closed the devices. The second,the values of WHO_AM_I was readed, but FXAS21002 is successful and FXOS8700C is failed(The value is 0x00), why?

 

Problem 2:

     I readed the valus of accelerometer are all 0x00, why?
