PDA TM3500: 3.5in PCAP Touch Module
3 Getting Started
This module was designed for use with a variety of Atmel ARM-based EK’s including the SAM4S Xplained Pro and
SAMA5D3 Xplained evaluation kits. This provides the fastest way to evaluate the performance of the
touchscreen and display.
The following sections provide basic information related to using and evaluating the Touch Module. Visit the
Precision Design Associates website (www.pdaatl.com/tm3500) or Atmel’s AT91 Community website
(www.at91.com) for more information related to this touch module or guidance appropriate for your specific EK.
3.1 Hardware Connections
The module interfaces with the EK board via the Host Interface at flex connector, J2. The Flat Flex Cable should
be inserted with flex contacts facing DOWN toward the PCB as shown in Figure 4 below.
This interface can be used connected to Atmel evaluation kits that support the “XPRO LCD” connector. Refer to
EK documentation to see if this interface is supported by the evaluation hardware and ensure proper matchup of
host signals.

3.2 Software
Several options exist when developing for the touch module whether targeting a custom host or an Atmel EK.
Support for the TM3500 is currently being built into upcoming releases of various Atmel resources.
Check the Precision Design Associates website (www.pdaatl.com/tm3500) for updates and links to demo binaries
for use with the TM3500.
3.2.1.1 Atmel Studio and Atmel Software Framework
Atmel Studio (www.atmel.com/atmelstudio) is Atmel’s free IDE and tool chain. It includes support for a variety of
Atmel’s MCUs devices and provides a means to start developing basic, “bare-metal” software for .the TM3500.
The Atmel Software Framework (asf.atmel.com) contains examples of code for interfacing with devices in the
maXTouch family of touch controllers. The capabilities of various maXTouch devices may differ, but the basic
communication protocol is common and can be applied to this module.
3.2.1.2 Linux Kernel / Android
The Linux Kernel (www.kernel.org) has included basic support for maXTouch touch devices since version 2.6.36.
The mainline driver has undergone considerable evolution since then.
Atmel hosts the AT91 community website with resources dedicated to developing their EKs for Android
(www.at91.com/android4sam) and Linux (www.at91.com/linux4sam)
In addition, Atmel maintains patches (www.github.com/atmel-maxtouch/linux) which provide numerous out-of-cycle
improvements to the mainline Linux Kernel driver for maXTouch devices.
