Edge detection in Blinka

See original GitHub issue

Hey @makermelissa!

We’re porting @olixr Mudpi application code to use Blinka on the core in order to allow users to use their Linux SBC https://github.com/mudpi/mudpi-core/issues/15 (previously RPI was the only supported one) which is almost done by @SecT0uch

One of the issues we encountered is that we had RPi.GPIO as a dependency that does edge detection for event addition and handling and we couldn’t find that reference on Blinka. We did find it on Circuitpython documentation but nothing on Blinka itself.

Another proposed solution was to use adafruit_debouncer for edge detection, do you think it could help?

Can you guys help us a bit on that, maybe I didn’t search in the correct place 😢

@makermelissa - many thanks. I realised that I just need to use BCM mode and then I can use RPi.GPIO as well as Blinka.

@ladyada - How does one use RPi.GPIO at same time? I’m getting an error message:
GPIO.setmode(GPIO.BOARD)
ValueError: A different mode has already been set!

I don’t think you can change modes because it needs to be in BCM mode for Blinka to work: https://github.com/adafruit/Adafruit_Blinka/blob/main/src/adafruit_blinka/microcontroller/bcm283x/pin.py#L7
