duc _Description
ro _{The STEVAL-TCS003V1 demonstration board is}
P _{based on the STMPE2403 port expander and the}
te ST7263BK6 microcontroller. It includes a PC GUI
le (graphical user interface). The objective of the
o _{board is to demonstrate the features and}
s _{capabilities of the STMPE2403 port expander}
b _{chip using a Windows®-based host software}
O _{application and one of ST’s several USB low-}
) ^{- speed microcontrollers (the ST7263BK6 is used}
t(s ^{in this demonstration board) acting as a control}
device. In the STEVAL-TCS003V1, the
c _{ST7263BK6 microcontroller acts as the I2C}
du ^{master and controls the STMPE2403 device,}
ro ^{which functions as an I2C slave. The STMPE2403}
is used to interface the matrix keypad, dedicated
P _{keys, special function keys, rotator controller and}
te PWM controllers. These interfaces are controlled
le using I²C communication between the master and
o _{slave devices. In run mode, events such as key}
s _{press (matrix, special function or dedicated keys),}
Ob^{rotator controller, power mode, etc. are captured}
STEVAL-TCS003V1
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.
