STEVAL-IHI001V1 Demonstration board for washing machine user interface based on the ST7LITE49M and STLED316S Data Brief Features ■ 8-bit ST7Lite49M MCU with I²C bus ■ STLED316S LED driver with key-scan ■ 3 displays and 32 LEDs as graphic interface ■ ICC connector and extra I²C bus connector ■ Wheel with 19 different washing programs ■ Powered directly from an AC notebook computer power supply ■ Additional program settings and adjustable spin speed ■ Adjustable LED brightness and lamp-test button ■ Fully stand-alone washing machine-like simulation ■ Connector to plug a daughter board (with automatic detection) 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.
