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 (16-bit 262,000 different shades)! 240x320 pixels with individual pixel control, this has way more resolution than a black and white 128x64 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. The code is written for Arduino but can be easily ported to your favorite microcontroller!
