interfacing of LMP91000EVM with arduino

Dear 6506831 - 

Thanks for posting and welcome to E2E Forum!

With just the board, what is available to interface to Arduino or TI MCU LaunchPad (using CCS or Energia (in that IDE or in CCS) is the I2C interface to the LMP91000, the VOUT of the LMP91000, which would go to ADC input on Arduino or LaunchPad MCU ADC, or you can interface to the onboard ADC16 (U2) via SPI. See schematic on page 7 here : https://www.ti.com/lit/ug/snau121a/snau121a.pdf

For the code, the MSP430 version is here:
