How to extend the CP NeoPixels??

by tkinsman on Sat Apr 14, 2018 1:12 pm

I have a CP classic, and want to add two of the 8-neopixel strips to it. (To get 26 neopixels total.)

Does anyone know if there is an easy way to get the "Data Out" off the built-in neopixels?

... Or, in other words...

I worry that the neopixel library might only allow one instance of a neopixel string in the system. Does anyone know if I can control the 10 Neopixels on the Circuit Playground ~and~ have another Neopixel strip attached?

i have attached a neopixel ring to a cp but treated it as a separate instance running from a different pin to the baked in ones. i don't know if you can piggy back on the internal control pin.

Thank you for the information. That means it can be done.

Do you have code handy to share?

There's no easy way to add more NeoPixels to the set that are mounted on the Circuit Playground. The data-out pin for the last pixel doesn't have any connection.

You can use the regular NeoPixel library in parallel with the CircuitPlayground library though.
