Overview

The Digilent Pmod MTDS (Revision A) is a gorgeous 2.8” touchscreen display with a powerful on-board

microcontroller that performs graphics processing tasks. The display is a capacitive touchscreen with QVGA

resolution (320×240) and 2 finger multi-touch support.

The most compelling aspect of the Pmod MTDS is the programming experience provided by its Multi-Touch Display

System (MTDS) Firmware and the associated libraries. These allow you to design sleek, stylish user interfaces very

quickly and with very little code. The timing dependent tasks are handled by the firmware, so integrating the

display into existing projects is also a snap. Some of the key functionality provided by the libraries include the

ability to draw basic shapes and text, draw images stored on microSD with binary transparency, draw buttons and

easily check if they have been pressed, and check the status and location of the user's two fingers. The libraries are

supported in Arduino IDE and Xilinx SDK, and have been tested with Ardiuno, chipKIT and Arty host boards.

Pmod MTDS™ Reference Manual boards should use the Pmod MTDS IP core and the libraries included with it. For information on downloading and using the Pmod MTDS IP core see the Using Pmod IPs Tutorial. After exporting to Xilinx SDK, follow the README.txt guide included in the examples folder. JP1 is used to select how to power the display's backlight. A single jumper should be loaded across 2 of the three pins in order to select the power source.
