Adding a external TI LMP91000 and LM4120 circuit to MetaMotionR via I2C

I would like to know after connecting the custom build board with Texas Instrument analog front-end chip (LMP91000) and a reference voltage controller (LM4120) to metaMotionR pin 3, 5, 6, 7, and 8 (See diagram). How can I
1. make MetaMotionR supply the Regulated 3V output from pin 7 to the peripheral board.
2. Read the values from pin 8?
3. Do I need to change the code in the firmware of your BLE controller or just the code in MetaBase App or do something else?
datasheet of LMP91000, LM4120, and schematic diagram of the peripheral boad are attached

    It should supply the voltage once the board is powered

    1. Read the values from pin 8?

    Use the APIs to read the gpio voltages

    You will need to write your own app

  • @Eric Thanks! Could I modify the code from your MetaBase App and use it to read from pin 8?
