[Microbit-Python] Driving Neopixels with Pxx other than P0, P1, P2?

[Nevil Hunt]

Hi Damien,


Thanks for the suggestion. I gave it a go but unfortunately it didn't bring it to life.

I tried P8,12,13,14,15,16 and none of them drive the NeoPixels.

If enabling NeoPixels on these additional Pxx pins would just be a simple s/w change it would be good to have as the P0,P1,P2 are precious resources.

Either way this is the first time I've had a play with NeoPixels and they are good fun!


Cheers,


Nevil

Hi Nevil,

Neopixels should work on all pins.... make sure the pin is not being
used for something else (eg display), then try doing write_digital on
that pin before using it as a neopixel output.

Cheers,
Damien.
