Example Summary

The following example configures TimerG in periodic mode and toggles the LED every 500ms. The device remains in SLEEP mode while waiting for an interrupt.

Note: Example requires Rev E3 or later of the MSPM0C1104 LaunchPad.

Device Migration Recommendations

This project was developed for a superset device included in the LP_MSPM0C1104 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-MSPM0C1104 User’s Guide.

Example Usage

Compile, load and run the example. LED1 will toggle every 500ms, and the device will remain in SLEEP while waiting for an interrupt.
