Touch sensing controller (TSC)
The STM32F301x6/8 devices provide a simple solution for adding capacitive sensing
functionality to any application. These devices offer up to 18 capacitive sensing channels
distributed over 6 analog I/O groups.
Capacitive sensing technology is able to detect the presence of a finger near a sensor which
is protected from direct touch by a dielectric (for example glass, plastic). The capacitive
variation introduced by the finger (or any conductive object) is measured using a proven
implementation based on a surface charge transfer acquisition principle. It consists of
charging the sensor capacitance and then transferring a part of the accumulated charges
into a sampling capacitor until the voltage across this capacitor has reached a specific
threshold. To limit the CPU bandwidth usage this acquisition is directly managed by the
hardware touch sensing controller and only requires few external components to operate.
