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 chip using a Windows®-based host software application and one of ST’s several USB lowspeed microcontrollers (the ST7263BK6 is used in this demonstration board) acting as a control device. In the STEVAL-TCS003V1, the ST7263BK6 microcontroller acts as the I2C master and controls the STMPE2403 device, which functions as an I2C slave. The STMPE2403 is used to interface the matrix keypad, dedicated keys, special function keys, rotator controller and PWM controllers. These interfaces are controlled using I2C communication between the master and 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. STEVAL-TCS003V1
