How easy would it be to run MicroPython on the KeyBow 2040? #6

Closed rtyley closed 1 year ago

rtyley commented 2 years ago

Unfortunately some of the differences between CircuitPython and MicroPython are a bit limiting for me - for example the time module is quite constrained (CircuitPython vs MicroPython). I don't need USB-HID support for my project, so how easy would it be to run MicroPython on it instead?

There's no specific build of Micropython for the KeyBow 2040, so far as I can see:

Would it be safe for me to use the standard rp2-pico build instead?

The standard Pico build should get you started, yes (they both have the standard 2MB flash). You could use one of our packed-with-libraries builds, but those extra libraries probably wont be that useful to you.

You can also peer into the depths of CircuitPython to figure out which pin goes to which key:

Ah, thank you!
