    Hi Lian,

    In the read register function I don't see the command to read from the register. So the 'address' sent should be 'or'ed to the command which is 0x20. It would be helpful to see CS, MISO, MOSI and SCLK signals at the same time to verify the commands are properly transmitted.

    Also, in the register write function I do not see that the command (0x40) is being added to the 'address', although it is being transmitted so it is not clear how this is being added to the function.

    Best regards,
    Bob B
