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.

AVR1909 3 8297A-AVR-04/10 The Display Xplained module is quite simple. It basically connects the TFT display SPI interface, resistive touch interface, and backlight interface from a 40pin FPC connector to two female pin-headers that fit the Xplain kit. In addition it has a program/debug interface th...
4 AVR1909 8297A-AVR-04/10 3.4 The SPI interface The Display Xplained module uses a simple SPI interface to communicate with the LCD module. This consist of a Chip-Select (CS) line, a clock line (SCL), and two data lines (SDI/SDO). The SPI is operated in mode 3, i.e. inactive clock is ‘high’, and dat...
