Feather Fire! I’m trying to load @Mark_Kriegsman 's Fire2012 sketch onto the Adafruit Feather M0 and am getting the error below. Not sure if this is a question for Mark or for @Phillip_Burgess – is it the M0 board support that doesn’t like the random() call? Or is this a FastLED-doesn’t-support-the-board issue?

Fire2012WithPalette.ino: In function ‘void loop()’:

I think I recall seeing this on other boards. Try changing random() to tandom(0,65535)

That work?

I changed it to random(0,65535) and it is compiling now. Thanks!!

Let me know how it works overall, too!

What a strange error. Good to know there’s a work around.

It’s because that particular platform doesn’t provide a zero-arguments version of random(), just the one- and two- argument versions.

So the workaround is to just call one of the ones that is provided!
