Data brief
STEVAL-ICB003V1
AM05056v1
To increase versatility, the design includes
features such as rotary encoder interface, power
management and a logic level input for a water
level sensor.
Description
The STEVAL-ICB003V1 demonstration board is a
general-purpose front panel solution suitable for
white goods, utilizing a TLED316S LED driver,
STMPE1208S capacitive touch sensor and an a
STM8S207K6 microcontroller from the STM8
series of 8 bit microcontrollers.
The purpose of the board is to demonstrate the
capabilities of ST’s STLED316S, STMPE1208S
and STM8S devices in a sophisticated front panel
application targeted at the front panel market
segment for DVD players, DVD recorders, set-top
boxes, washing machines, etc., while keeping
system cost as low as possible.
The design focuses on 3 key areas: standby
management for low power consumption, general
touchkey and rotary encoder input and water level
sensing of a 38-43 kHz output from a water level
sensor.
