STM8/128-EV/TS
STM8S touch sensing evaluation board
Introduction
The STM8S touch sensing evaluation kit (STM8/128-EV/TS) provides a platform that
introduces users to STMicroelectronics capacitive touch sensing firmware library.
The kit contains an STM8S touch sensing (TS) evaluation daughterboard (STM8Sxxx-TS1)
in addition to the STM8/128-EVAL board.
The STM8S touch sensing evaluation daughterboard provides an evaluation platform for
resistor-capacitor (RC) touch sensing technology for an implementation using 5 keys and
one slider.
The STM8S TS evaluation kit provides a software solution for transforming any 8-bit STM8
microcontroller (MCU) into a capacitive touchkey controller.
For further details about the touch sensing software library, please read the technical
documentation available on www.st.com/touch-sense-sw-lib.
