STEVAL-IHI001V1 STMicroelectronics

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