I have the MSP430FR6989 MCU and BOOSTXL-BASSENSORS connected. I believe the booster pack just needs to be on top of the MSP430 Launchpad as they are both 40 pin compatible. 

Assuming I have these connected correctly, I tried running this code. It does compile. However, I'm trying to find what the sensor measurement values are by reading the register values. I'm attempting to do this by adding the watch expressions for OPT3001_ADDRS or OPT3001_RESULT_REG, but the  error "identifier not found" pops up.

Does anyone know what I am doing wrong here? How can I read where the sensor values are stored? I think they would be in a register of some sort.
