STM8S touch sensing library
The STM8S touch sensing library is composed of a set of functions, variables and structures
(see
The STM8S touch sensing library allows detecting physical touch on the capacitive sensing
keys by controlling the charge/discharge timing cycle of an RC network composed of a
single resistor and the touch electrode capacitance. Any variation in the RC
charge/discharge timing resulting from a change in the electrode capacitance is detected
and then filtered.
For detailed information related to the RC acquisition principle, refer to the application note
AN2927 available on http://www.st.com/mcu.

STM8S touch sensing library working principles
The STM8S touch sensing library is a set of compatible C files. It includes the API that
makes the interface with the other software layers, a core set of files performing basic
functions (main state machine, key state machine, services), plus the drivers to control
timers and GPIOs.
