Request for sawtooth wave to be added to FastLED. You already have a triangle wave. #565

Please see the following diagram:

which shows that a triangle wave is not a sawtooth wave, thus my request.

As a matter of fact, a sawtooth wave in both directions would even be better.

Check out "beat8( BPM)", which is the sawtooth wave from 0-255 that's used to generate all the other waveforms. "beat88( BPM)" is the same, but with higher precision.

I can leave this ticket open as a reminder to myself to add synonyms called "sawtooth8" or something next time there's an update.

Thanks. I'll study and play around with those more carefully.

Also please remove the "aka sawtooth" phrase from the wiki entry on wave functions to:

  1. Not lead folks astray that are just learning these concepts
  2. Avoid confusion with the aptly named functions listed in this issue
