CircuitPython Displayio Quickstart

You will need a board capable of running CircuitPython such as the Metro M0 Express or the Metro M4 Express. You

can also use boards such as the Feather M0 Express or the Feather M4 Express. We recommend either the Metro M4

or the Feather M4 Express because it's much faster and works better for driving a display. For this guide, we will be

using a Feather M4 Express. The steps should be about the same for the Feather M0 Express or either of the Metros. If

you haven't already, be sure to check out our Feather M4 Express (https://adafru.it/EEm) guide.

Preparing the Breakout

Before using the TFT Breakout, you will need to solder the headers or some wires to it. Be sure to check out

the Adafruit Guide To Excellent Soldering (https://adafru.it/drI). After that, the breakout should be ready to go.

Required CircuitPython Libraries

To use this display with displayio , there is only one required library.

https://adafru.it/FvR

First, make sure you are running the latest version of Adafruit CircuitPython (https://adafru.it/Amd) for your board.

Next, you'll need to install the necessary libraries to use the hardware--carefully follow the steps to find and install

these libraries from Adafruit's CircuitPython library bundle (https://adafru.it/zdx). Our introduction guide has a great

page on how to install the library bundle (https://adafru.it/ABU) for both express and non-express boards.

Remember for non-express boards, you'll need to manually install the necessary libraries from the bundle:

adafruit_st7789

Before continuing make sure your board's lib folder or root filesystem has the adafruit_st7789 file copied over.

Code Example Additional Libraries

For the Code Example, you will need an additional library. We decided to make use of a library so the code didn't get

overly complicated.
