The sample code we are providing you is designed to be run on a variety of Adafruit boards that can use the GFX library. The screenshots shown here were using the 2.4 inch 320x240 TFT FeatherWing but we have also provided options for the 3.5 inch 480x320 FeatherWing, Adafruit HalloWing and PyGamer displays.
When using the TFT FeatherWings you also need a Feather board. We recommend some version of M0 or M4 or any other 32-bit Feather. The custom fonts we will be using take up a lot of memory and cannot be run on 8-bit boards such as a 32u4. We used a Feather M0 Express. The M4 boards are much faster and would be an even better choice.
You also need to download and install the Adafruit GFX library. For details on how to do that visit this tutorial. You also need support for whatever display you are using. Go to the learning guide for the particular display you are using to see which libraries are needed to support it.
Finally you will need the sample sketch for this tutorial which can be found on GitHub using the button below.
