1 / 4 page Data Brief For further information contact your local STMicroelectronics sales office. December 2008 Rev 1 1/4 4 STEVAL-TCS001V1 24 bit port expander demonstation board with LCD, keypad, and PWM interfaces based on the STMPE2401 Features ■ User friendly environment – Standalone mode –PC GUI mode ■ Dual power supplies –USB – External supply ■ Full support with various "power saving" modes of port expander 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.
