    Hi Alfie,

    In the screenshot provided here, we would recommend 0x20 to be written to 0x00, not 0x01. The recommended flow for this initialization is the following: 

    board.WriteI2C(devAddr,0x32,0x01)

    board.WriteI2C(devAddr,0x21,0x01)

    board.WriteI2C(devAddr,0x33,0x01)

    board.WriteI2C(devAddr,0x20,0x00)

    board.WriteI2C(devAddr,0x32,0x02)

    board.WriteI2C(devAddr,0x33,0x00)

    Would you be able to provide a register dump of the UB962 while this issue is being observed? 

    Best,

    Zoe
