Product overview
Description
STMT/8L-EV1 is the STM8L evaluation board with a touch-sensing library which enables designers, who are familiar with the standard STM8Lxxx 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 touch-sensing library is a complete, free source-code solution to transform any 8-bit STM8L microcontroller into a capacitive touchkey controller.
-
