Smart touchpanel interface based on the STMPE1208S, STLED316S and STM8S
  • active Active

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.

To increase versatility, the design includes features such as rotary encoder interface, power management and a logic level input for a water level sensor.
