Updated Firmware with CircuitPython 3.2.0

Published on 2018-09-30 in µGame.

CircuitPython 3.2.0 has been released a while ago, and brings a lot of bug fixes and some performance improvements. It would be nice to use it for µGame. Unfortunately, it also had some changes in how audio is handled, and since that interacted with available memory in ways that made the example games not work, it required more work on my part than just rebasing the repository.

However, I managed to work around the problems, and a new version of the firmware is now available at https://github.com/python- ugame/circuitpython/releases/tag/ugame10-3.2.0 . There is also a release of the Vacuum Invaders game specially updated for that version of firmware: https://github.com/python-ugame/vacuum-invaders/releases/tag/3.2.0 . The other example games, as well as the tutorial, should work without any changes.

In order to upgrade your device, you need to download the .uf2 file, and copy it to the TRINKETBOOT disk that appears when you press the “reset” button (located next to the direction buttons) twice. Once the file is copied, the device will reboot with the new firmware in place.
