2 Capacitive Touch Measurement

The QTouch® Modular Library supports PTC measurement of self-capacitance and mutual capacitance touch sensors on a selection of AVR®, Arm® Cortex-M0+, Arm Cortex-M23, and Arm Cortex-M4 microcontrollers.

In all current capacitive touch measurement methods, one of two basic functional approaches is implemented: Self-capacitance or mutual capacitance.
