TMS320F280049C: Motor Control ADC Voltage Offsets Calibration

Part Number: TMS320F280049C


I'm currently completing Lab 02 of the "InstaSPIN Projects and Labs User's Guide".  I'm using a F280049C LaunchPad paired with a DRV8320RS BoosterPack to drive a custom motor.

When I calculate the ADC voltage offsets using the C2000 InstaSPIN Universal GUI, I get offsets close to 1.0.  However, when I run the example code from Lab 02, I get voltage offsets close to 0.5.  Is the C2000 InstaSpin Universal GUI wrong?
