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.
