Device Migration Recommendations

This project was developed for a superset device included in the 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-MSPM0C1106 User’s Guide.

Example Usage

Compile, load and run the example. Provide a valid voltage to A0_2 between 0 - VCC. Monitor LED1 while input voltage changes.

On powerup, the ADC pin(s) used in this example are by default set to the correct analog mode. Therefore, calls to DL_GPIO_initPeripheralAnalogFunction for pinmuxing those pins are not needed.
