Description

Add some jazz & pizazz to your project with a color capactive touchscreen LCD. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful! 240x320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128x64 display. As a bonus, this display has a capacitive single-touch touchscreen attached to it already, so you can detect finger presses anywhere on the screen. (Adafruit also have a resistive touchscreen version of this display breakout)

This display has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. The display can be used in two modes: 8-bit and SPI. For 8-bit mode, you'll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). SPI mode requires only 5 pins total (SPI data in, data out, clock, select, and d/c) but is slower than 8-bit mode. In addition, 2 I2C pins are required for the touch screen controller.

Adafruit wrapped up this display into an easy-to-use breakout board, with SPI connections on one end and 8-bit on the other. Both are 3-5V compliant with high-speed level shifters so you can use with any microcontroller. If you're going with SPI mode, you can also take advantage of the onboard MicroSD card socket to display images. (The microSD card not included, but any will work)

Of course, they wouldn't just leave you with a datasheet and a "good luck!". For 8-bit interface fans we've written a full open source graphics library that can draw pixels, lines, rectangles, circles, text, and more. For SPI users, they have a library as theyll, its separate from the 8-bit library since both versions are heavily optimized. Adafruit also have an interfacing library for the capacitive touch screen
