The STM8S touch sensing evaluation kit (STM8/128-EV/TS) enables designers, who are familiar with standard STM8S microcontrollers, to create higher-end look-and-feel user interfaces by replacing conventional electromechanical switches with touch sensing controls. Designers can thus combine touch sensing functions with traditional MCU features such as communication, LED control, beeper, LCD control, and so on.
The kit contains an STM8/128-EVAL board, and an STM8S touch sensing evaluation daughterboard (STM8Sxxx-TS1) which provides an evaluation platform for the resistor-capacitor acquisition principle.
The touch sensing library is a complete, free source-code solution to transform any 8-bit STM8 microcontroller into a capacitive touchkey controller.
