All of the files required for this project (the code, graphics, and font) are available for download on GitHub. There are two code files for this project, our regular code.py along with secrets.py

You'll need to edit secrets.py with your applicable information. You can find more info on all of the code files in the next two pages of this guide.

CircuitPython Code

In the embedded code element below, click on the Download: Project Zip link, and save the .zip archive file to your computer.

Then, uncompress the .zip file, it will unpack to a folder named PyPortal_on_this_day.

Copy the contents of the PyPortal_on_this_day directory to your PyPortal's CIRCUITPY drive.

Downloading the libraries

Per the CircuitPython Libraries page previously, download the library bundle appropriate for your version of CircuitPython. Copy the below library files/folders to a directory named lib on your CIRCUITPY drive.

Make sure to add the necessary libraries to the lib folder, info on how to do this can be found in the "PyPortal CircuitPython Setup" section

This project uses the following CircuitPython libraries:

  • adafruit_bitmap_font (directory)
  • adafruit_bus_device (directory)
  • adafruit_display_shapes (directory)
  • adafruit_display_text (directory)
  • adafruit_esp32spi (directory)
  • adafruit_io (directory)
  • adafruit_miniqr.mpy (file)
  • adafruit_pyportal.mpy (file)
  • adafruit_requests (file)
  • adafruit_sdcard.mpy (file)
  • adafruit_touchscreen.mpy (file)
  • neopixel.mpy (file)

This is what the final contents of the CIRCUITPY drive will look like:

Double check

See the directory listing above and double check that you have all the files listed to make this project function. If any are missing or in an incorrect directory, move them so they're in the right places. The project will not work correctly unless the files are in the right locations.
