CircuitPython is a programming language based on Python, one of the fastest growing programming languages in the world. It is specifically designed to simplify experimenting and learning to code on low-cost microcontroller boards. Here is a guide which covers the basics:
Be sure you have the latest CircuitPython for the PyPortal loaded onto your board, as described here. You will want at least version 4.1 (possibly a beta version of it) for maximum graphics performance.
CircuitPython is easiest to use within the Mu Editor. If you haven't previously used Mu, this guide will get you started.
Libraries
Plug your PyPortal board into your computer via a USB cable. Please be sure the cable is a good power+data cable so the computer can talk to the board.
A new disk should appear in your computer's file explorer/finder called CIRCUITPY. This is the place we'll copy the code and code library. If you can only get a drive named PORTALBOOT, load CircuitPython per the guide mentioned above.
Create a new directory on the CIRCUITPY drive named lib.
Download the latest CircuitPython driver package to your computer using the green button below. Match the library you get to the version of CircuitPython you are using. Save to your computer's hard drive where you can find it.
With your file explorer/finder, browse to the bundle and open it up. Copy the following folders and files from the library bundle to your CIRCUITPY lib directory you made earlier:
- adafruit_bitmap_font
- adafruit_bus_device
- adafruit_display_shapes
- adafruit_display_text
- adafruit_imageload
- adafruit_button.mpy
- adafruit_pyoa.mpy
- adafruit_cursorcontrol.mpy
- adafruit_touchscreen.mpy
All of the other necessary libraries are baked into CircuitPython!
Your CIRCUITPY/lib directory should look like the snapshot below.
