MCT8329A: MCT8329A GUI setting procedure

MCT8329A: I2C target address

Hung-Chen Yu

Part Number: MCT8329A

The GUI V1.1.0 

I have to change the I2C target address to 0x0 to successfully connect to the driver.

Same issue with GUI v1.0.0

However, in the datasheet it said the address 0x60 and so as the the default on the GUI v1.1.0

    Hi Hung-Chen,

    The default value of the I2C target address is set as 0x60. Given this, the GUI is also default set to 0x60 for I2C target address so that they can properly communicate as factory settings. It seems that somehow your device has been configured with 0x00 as the I2C_TARGET_ADDR. To fix this so that your device is configured with the default I2C target address for when you access the GUI, you can configure I2C_TARGET_ADDR to 0x60 in the Register Map tab of the GUI. After you do this, press the "write to EEPROM" button to write these settings to your device EEPROM. See the screenshot below:

    Once you power cycle the device, your device will be configured to the default I2C target address of 0x60. 

    Best,

    Robert
