STMicroelectronics touch-sensing libraries provide a complete robust free source-code solution to be used on STM8L, STM8TL5x, STM32F0xx, STM32F3xx and STM32L1xx microcontrollers. This solution allows designers familiar with the use of standard microcontrollers to create higher-end human interfaces by replacing conventional electromechanical switches by capacitive sensors.
The xxxx-TOUCH-LIB is part of the application firmware. It allows combining various capacitive sensing touchkeys, linear or rotary touch sensors with traditional MCU features (communications, control of LEDs, beeper or LCD) in the same application.
Two capacitive acquisition principles, surface Charge Transfer (CT) and ProxSenseTM, are available and can be configured at compiling level. Both acquisition principles offer the same advanced processing algorithms to filter out noise and to compensate environmental parameters such as temperature, humidity, and power supply variation.
