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.
