Accessing buttons and switch of wio terminal with ardupy

Products & Technology ArduPy
12

For those interested, here is a solution using Circuitpython. The only required library not included in the distribution is the debounce library. Works reasonably well. To get this to work with Ardupy, I had to put in the exact pin numbers which was a real pain–it was for this reason that after coding up the 2nd button I bailed on that approach. Until regular updates occur with Ardupy, I’m gonna work with Circuitpython. However, I’d love to have true interrupts with the micropython support.

Finally, I know the code could be cleaner…

Cheers
