2.8 TFT Touch Shield for Arduino

Tftshield Lrg

2.8 TFT Touch Shield for Arduino. Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.8″ diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240×320 pixels with individual pixel control. It has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library – you’ll have it running in under 10 minutes!

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. The shield does require a lot of pins: 12 lines total for the display, 13 total if you use the microSD card.

Of course, we wouldn’t just leave you with a datasheet and a “good luck!” – we’ve written a full open source graphics library that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x, y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

  1. Hi, how about using less pins by integrating an atmega 328 directly to the board and use some i2c protocol….
    (like liquideware…)

    Best regards

  2. @mboyer – please read the page:

    Frequently Asked Questions

    I was just looking through the datasheet and I notice there is an SPI interface available. Why do you use the parallel interface? SPI would be better fewer pins!

    Even though the display driver supports SPI, we have not found any displays that could use it – the pins are simply not available on the display connector. Also, SPI would be incredibly, frustratingly slow for such a large screen. If you need an SPI display, check out many of our other offerings, nearly all support SPI-like protocols!

    All the pins are used! How can I connect anything to the Arduino??

    We suggest using a protoshield (with stacking headers) or a proto-screwshield to access the unused pins (2, 3, and analog 4 and 5). You can connect various i2c sensors or analog sensors to analog 4&5. You can also connect an i2c port expander to get more I/O pins. If you desperately need more pins, and you’re careful, you can use the 8 datapins while the TFT isn’t being written to – they are high-z and unused as long as the WR and RD pins are high

  3. I read that, it was just an idea to delegate the display to a dedicated arduino.

Sorry, the comment form is closed at this time.
