Description

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.
