STEVAL-TCS003V1

24-bit port expander demonstration board with LCD,

keypad, and PWM interfaces based on the STMPE2403

Features

– Standalone mode

–PC GUI mode

Description

The STEVAL-TCS003V1 demonstration board is

based on the STMPE2403 port expander and the

ST7263BK6 microcontroller. It includes a PC GUI

(graphical user interface). The objective of the

board is to demonstrate the features and

capabilities of the STMPE2403 port expander

application and one of ST’s several USB low-

speed microcontrollers (the ST7263BK6 is used

in this demonstration board) acting as a control

device. In the STEVAL-TCS003V1, the

master and controls the STMPE2403 device,

is used to interface the matrix keypad, dedicated

keys, special function keys, rotator controller and

PWM controllers. These interfaces are controlled

slave devices. In run mode, events such as key

press (matrix, special function or dedicated keys),

rotator controller, power mode, etc. are captured

and displayed on the LCD screen and in the scan

window of the PC GUI. The capability of the

rotator controller is demonstrated using a 3-pin

jumper connector. For interfacing with the PC

GUI, the application layer is built above the USB

core library, making the USB interface hardware

control transparent for developers.
