1 Introduction
The Display Xplained module gives the possibility to evaluate a 240 x 320 pixel
(QVGA) graphical RGB TFT display with a 4-wire touch interface and LED
backlight. The display is interfaced with a simple SPI interface to send and receive
commands and data. The Xplain kit provides tested low–level drivers and high-
level functions in order to get the developer quickly up to speed with his application
development.
