Device Migration Recommendations

This project was developed for a superset device included in the LP_MSPM0G3507 LaunchPad. Please visit the CCS User’s Guide for information about migrating to other MSPM0 devices.

Low-Power Recommendations

TI recommends to terminate unused pins by setting the corresponding functions to GPIO and configure the pins to output low or input with internal pullup/pulldown resistor.

SysConfig allows developers to easily configure unused pins by selecting BoardConfigure Unused Pins.

For more information about jumper configuration to achieve low-power using the MSPM0 LaunchPad, please visit the LP-MSPM0G3507 User’s Guide.

Example Usage

Compile, load and run the example. RGB LEDs will toggle with red being opposite of blue and green.

USER_TEST_PIN GPIO will mimic the behavior of the LED1 and LED3 pins on the BoosterPack header and can be used to verify the LED behavior.
