1 Overview
This solution enables designers, comfortable with the use of standard microcontrollers, to
create higher-end “look and feel” user interfaces by replacing conventional electro-
mechanical switches with touch sensing controls.
Designers can combine touch sensing functions with traditional MCU features
(communication, LED control, beeper, LCD control, etc.).
The touch sensing firmware library is part of the application firmware.
Maturity, robustness, flexibility and performance make this solution simple to implement with
a low “time to market” period making it easy to develop all types of applications including
mobile phones, cooking appliances and printers only to name a few.
The STM8S TS evaluation kit comes pre-programmed with evaluation firmware that
manages 5 touch keys and one slider all available on the touch sensing daughterboard.
Using this kit, the user can easily evaluate the touch sensing software features and
performances by monitoring sensing parameters using an LCD display interface.
In development mode, designers are able to debug, modify, adapt or integrate the touch
sensing library in application firmware using a USB debugging and programming tools:
● Raisonance RLink debugger/programmer for ST microcontrollers
● STice in-circuit emulation system
● ST MCU Toolset with ST Visual Develop (STVD) IDE and ST Visual Programmer
(STVP) programming interface
