2.8″ TFT Touchscreen – 320×240 pixels in 16 bit color – bitmaps!

We have lots of 2.8″ TFT breakouts in stock and a brand new tutorial for drawing bitmaps of any size from SD storage!

We have an example sketch in the library showing how to display full color bitmap images stored on an SD card. You’ll need an SD or microSD breakout board such as this one . You’ll also need to download our SD library modifyied to allow faster reads (these changes will be added to arduino v23) but for now you can download the new library here . Download the library by clicking the Downloads button and uncompressing the folder. Replace the files in your ArduinoIDE/libraries/SD folder and restart the IDE.

Wire up the TFT as we have before (see above) and then wire up the microSD card breakout. Connect the SD card with DI going to pin 11, DO going to pin 12 and SCK going to pin 13 (this is standard on all our shields) Then pin 10 goes to CS. Copy the woof.bmp and miniwoof.bmp files to a microSD card and insert it into the breakout. Run the tftbmp example sketch in the TFTLCD library, you should see the images show up. If not, check the serial monitor for hints as to why it may not be working.

NEW PRODUCT – 2.8″ 18-bit color TFT LCD with touchscreen breakout board! Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (2.8″ diagonal) bright (4 white-LED backlight) and colorful (up to 18-bit 262,000 different shades)! 240×320 pixels with individual pixel control, this 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.

This display has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You’ll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). 4 pins are required for the touch screen (2 digital, 2 analog) but because of the way resistive touch screens work, we can share pins with the LCD so the entire setup can be run by 12 pins (10 digital, 2 analog).

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. Be sure to see our detailed tutorial at the product page where we discuss how to use the LCD, and go through the example Arduino library and example code.
The library and example code is written for Arduino but can be easily ported to your favorite microcontroller!
