Description
The STEVAL-TCS004V1 demonstration board is
based on the STMPE1601 port expander and the
ST7263BK6 microcontroller.
STEVAL-TCS004V1
The objective of the board is to demonstrate the
features and capabilities of the STMPE1601 port
expander chip using a Windows®-based host
software 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-TCS004V1, the ST7263BK6
microcontroller acts as the I2C master and
controls one STMPE1601 device, which functions
as an I2C slave. The STMPE1601 is used to
interface the matrix keypad, dedicated keys,
special function keys and PWM controllers.
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.
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.
