UPDATED GUIDE: Adafruit 3.5″ 320×480 Color TFT Touchscreen Breakout #CircuitPython #Feather #Adafruit #AdafruitLearningSystem #Display @Adafruit @MakerMelissa

The Adafruit 3.5″ 320×480 Color TFT Touchscreen Breakout guide has been updated with a new section on using CircuitPython displayio.

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 control, 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 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. The display can be used in two modes: 8-bit or 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.
