Introduction
The New Terasic Multi-touch LCD Module Second Edition (MTL2) is an all-purpose capacitive
touch-screen for FPGA applications and provides five points multi-touch gesture support. An IDE
cable with an IDE to GPIO (ITG) adapter is used to interface with various Terasic FPGA
development boards through a 2x20 GPIO interface on the MTL2. The kit contains complete
reference designs and source code for an ePhoto demonstration and Painter application. This
chapter provides the key information about the kit.

Figure 1-2 shows the power adapter for the MTL2. Due to the fact that the LCD panel in the
MTL may consumes more power than some FPGA boards can provide. a dedicated power adapter
for MTL2 is required as shown in Figure 1-3.

The key features of this module are listed below:
800x480 pixel resolution LCD with 24-bit color depth
Five-point touch support
Gesture support
IDE interface
2x20 GPIO interface with ITG adapter
22..2

MMTTLL22 KKiitt
The MTL2 kit is assembled via three components:
Multi-touch LCD Module
IDE Cable
IDE to GPIO (ITG) adapter
The IDE cable is used to provide a high-speed signal transmission for 33 MHz video signals. The
ITG adapter is designed to map the standard IDE pin assignment to the 2x20 GPIO interface on the
FPGA boards.
