Hey! I created an open source firmware called “Picoware”. It has support for 3 languages/SDKs (Circuit Python, Arduino IDE, and C/C++ SDK) and already has many features included (social media, weather, GPS, Bluetooth functions, Games, Screensavers, WiFi functions, and more).
I delayed this post for a few months but I just received the email that my Pico Calc is on the way so I figured now was the best time to post and look for collaborations.
Pico Calc supported has not been added yet (because mine just shipped today)
Here’s the GitHub link: GitHub - jblanked/Picoware: Open-source custom firmware for PicoCalc, Video Game Module, and other Raspberry Pi Pico devices
Let me know your thoughts and if you’re interested in helping.
