Touch Library

Touch Library for MCC Melody is a royalty-free software library for developing touch applications on 8-bit microcontrollers. Developers can use it to integrate touch-sensing capability into their applications. The library supports both self-capacitance and mutual capacitance acquisition methods.

Refer to the microchip developer pages listed under "MCC Melody Touch Library Configurator" for more information.
