13.5.1.3 I2C Reads/Writes with Multi-Byte Register Addresses

These I2C commands will work for any I2C address on the local bus and remote devices configured in the target ID and target alias registers of the device. The 8-bit form of I2C addresses should be used.

    board.ReadI2C(Device Address, Register Address Byte 2,[Register Address Byte 1, # of Bytes]) OR board.ReadI2C(Device Address, Register Address Byte 2, [Register Address Byte 1])I2C Read Command for devices with multi-byte register addresses

    • Accepts both hex & decimal inputs
    • Number of bytes will default to 1 if omitted
    • Ex: board.ReadI2C(0x60, 0x30, [0x00]) will return the value in Register 0x3000 for the device with address 0x60 (8-bit form)

    board.WriteI2C(Device Address, Register Address Byte 2, [Register Address Byte 1, Data])I2C Write Command for devices with multi-byte register addresses

    • Accepts both hex & decimal inputs
    • Number of bytes will default to 1 if omitted
    • • Ex: board.WriteI2C(0x60, 0x30, [0x01, 0x01]) will set Register 0x3000 of the device with address 0x60 (8-bit form) to have a value of 1
