STEVAL-IHI002V1
User interface for home appliance / S-Touch™ daughter
demonstration board
Features
12-bit GPIO device with additional 12-channel
capacitive sensing sensors
Interface with MCU through I²C bus.
Fast and accurate results at very low power
consumption
Description
This demonstration board is designed to
modernize or even fully replace a mechanic
keyboard. The demonstration board is based on
the STMPE1208S device, a 12-bit GPIO
expander with an additional 12-channel capacitive
sensing sensor, which is able to interface a main
MCU through I²C bus. The demonstration board is
designed to work as a daughter board for the
STEVAL-IHI001V1 (washing machine user
interface). Once plugged in, the STEVAL-
IHI002V1 is automatically detected by the mother
board, replacing the mechanic keys by a wheel, a
slider and 5 buttons.
