Example Summary
This example implements an I2C Controller using the MSP Communication modules - I2C. This example demonstrates sending commands to an I2C Target to read from or write to its memory address and shows the response.

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
Connect SDA and SCL of I2C Controller to SDA and SCL of I2C Target respectively. Compile, load and run the example.
Please refer to MSPM0 Communication Modules - I2C User Guide for more details.
