STEVAL-IHI002V1

STEVAL-IHI002V1 User interface for home appliance / S-Touch daughter demonstration board Data Brief Features 12-bit GPIO device with additional 12-channel capacitive sensing sensors Interface with MCU through IC bus. Fast and accurate results at very low power consumption Description STEVAL-IHI002V1 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 IC 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.
