Description

The objective of this STEVAL-TCS001V1

demonstration board is to display to the user the

features and capabilities of the port expander chip

STMPE2401 using a windows-based host

software application and one of several USB low-

speed microcontrollers ST72F63B from ST acting

as a control device. In this demonstration board,

the ST72F63B microcontroller acts as the I²C

master and controls two STMPE2401 devices

functioning as I²C slaves. The two STMPE2401

devices are used to interface LCD, normal

keypad, rotator controller, dedicated keys and 6

PWM outputs. All these interfaces are controlled

by just using I²C communication between master

and slave devices. All events like dedicated key

press (four direction keys), keypad key press

(4 x 4 keypad), rotator direction, power mode etc.

are captured and displayed in LCD screen and in

the scan window of PC GUI. For interfacing with

the PC GUI, the application layer is built above the

USB core library that makes all the hardware

control of the USB interface transparent for the

developers. The PC GUI supports various power

saving modes of port expander and wake up

feature to get back to default operational mode. In

addition the board has the provision for an

alternate I²C path for external control. The board

also has ICC connectors to re-program the ST7

microcontroller Flash memory.
