This is an economical bundle of items to get you started using a 2.8-inch LCD TFT touch panel from 4D Systems on your Arduino. It includes the touchscreen display module itself (which comes with a header strip and 5-way jumper cable) and an Arduino adapter shield. All you'll need to provide is your own Arduino system. The shield is compatible with most Arduino boards and clones, including Uno, Mega, Due, Galileo, etc.
Arduino Display Module Pack Contents
- uLCD-28PTU programmable display with 240×320-pixel resolution, 65K colors, on-board speaker and resistive touchscreen
- Adaptor-Shield-II Arduino adapter with pass-through headers and configuration jumpers
Arduino Display Module Pack Overview With this Arduino Display Module Pack, you'll be able to start using the display in seconds. Just plug the adapter shield into your Arduino, then use the supplied cable to connect the display to the shield.
The uLCD-28PTU display has a comprehensive range of serial commands ready to be received from your Arduino, which can instruct it to draw primitives (e.g. lines, rectangles, circles, text), display images, play sound, play video, and log data to a microSD card.
It utilizes your Arduino's UART serial port, plus a single digital pin for reset of the display. Power for the display can come either through your Arduino or from an external source. Follow the link above to the Adaptor-Shield-II page for details about pin and power configuration.
Programmable Display As well as using the display module as a serial slave to your Arduino, it is possible to reprogram it to be completely or partially autonomous, programmed in a C-like language (4DGL) using the 4D Workshop4 IDE. That IDE also has a graphics-based programming tool, ViSi-Genie, which can generate 4DGL code for you (and there's an Arduino library for that environment as well, so you can quickly set up pre-made buttons, sliders, or gauges that interact with your Arduino). The included header strip can be used for making a connection to a breadboard to assist in programming or as an interface to external electronics when the display is operating autonomously. Follow the link above to the uLCD-28PTU page for more information.
There's a couple of USB-to-Serial adapters available in the Optional Recommended Products list below. Using one of those is recommended if you ever want to program the display for autonomous function, to update the firmware, or to use the ViSi-Genie environment with its Arduino library. Either adapter also can act as an alternative power source for the display (when connected to the shield's H2 header) in case your Arduino is unable to provide enough (e.g. it's already using too much current, or it's a 3.3V Arduino in which case the display will need a 5V source).
Arduino Libraries Available See the 4D Workshop4 IDE page to download the software as well as documentation and serial libraries. Some of the documentation, and the links to serial libraries, have versions for three different graphics chips; the PICASO versions apply to the display in this kit.
