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 Board→Configure 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. TimerG0 will output a pair of 62.5Hz edge aligned PWM signals on PA12 and PA13. PA12 is configured at a 75% duty cycle. PA13 is configured at a 50% duty cycle. Monitor the PWM signals on PA12 and PA13.
