25068 HMI4: Implementing Capacitive Touch I2C Host Interface for MTCH2120 (August 2025)
In this class you will learn how to implement the MCC Harmony I2C Host Driver for the MTCH2120 capacitive touch sensing controller, including understanding its architecture, commands, and capabilities, adding the I2C host module to an MCC Harmony project, and modifying the host interface to read and display touch sensor status.
This is a recording of the course 25068 HMI4 - Implementing Capacitive Touch I2C Host Interface for MTCH2120 from the 2025 MASTERs Conference.
This class teaches how to implement the MCC Harmony I2C Host Driver for the MTCH2120 capacitive touch sensing controller. Participants will learn the basic architecture, commands, and capabilities of the MTCH2120, add the I2C host module to an MCC Harmony project, and modify the host interface to read and display touch sensor status.
Prerequisites:
Basic knowledge of working on projects in the MPLAB X IDE would be helpful.
