STEVAL-IHI001V1 demonstration board: washing machine

user interface based on the ST7LITE49M and STLED316S

Introduction

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 STEVAL-IHI001V1 to operate as a

capacitive single touch keyboard.
