Description

Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (3.5″ diagonal) bright (6 white-LED backlight) and colorful! 480×320 pixels with individual RGB pixel keep watch over, this has way more resolution than a black and white 128×64 display, and double our 2.8″ TFT. As a bonus, this display has a resistive touchscreen attached to it already, so you’ll be able to detect finger presses anywhere on the screen. This display has a controller built into it with RAM buffering, so that just about no work is done by the microcontroller. The display can be utilized in two modes: 8-bit or SPI. For 8-bit mode, you can need 8 digital data lines and 4 or 5 digital keep watch over lines to read and write to the display (12 lines total). SPI mode requires only 5 pins total (SPI data in, data out, clock, choose, and d/c) but is slower than 8-bit mode. As well as, 4 pins are required for the touch screen (2 digital, 2 analog). Of course, Adafruit wouldn’t just leave you with a datasheet and a “good luck!”. Take a look at their detailed tutorial for wiring, test and example code! For 8-bit interface fans they’ve written a full open source graphics library that can draw pixels, lines, rectangles, circles, text, and more. For SPI users, there’s a library as well, it is separate from the 8-bit library since both versions are heavily optimized. Adafruit also has a touch screen library that detects x, y and z (pressure) and example code to demonstrate all of it.
