7.1 Microchip Touch Library

The Microchip Touch Library supports self-capacitance and mutual capacitance touch sensors on a selection of AVR, PIC, SAM, and PIC32 microcontrollers. It provides the required Application Programming Interface (API) for the PTC configuration, sensor data acquisition, and touch status update. The QTouch configurator (embedded into Atmel START) provides a seamless interface to incorporate the Microchip Touch Library into the user application.
