STEVAL-IHI001V1
Data Brief
STEVAL-IHI001V1
Description
The STEVAL-IHI001V1 is a demonstration board
designed to simulate the user interface of a
modern washing machine.
The board is based on the low-cost 8-bit
ST7LITE49M microcontroller equipped with an
I²C bus interface, and the STLED316S serial
interfaced 6-digit LED controller with key-scan.
The demonstration board is designed to work as a
stand-alone application, or as a motherboard for
the STEVAL-IHI002V1 daughter board, which
features the STMPE1208S capacitive sensing
device and can be plugged into the STEVALIHI001V1 to operate as a capacitive single touch
keyboard.
