That won’t do. Now what?
Because NeoPixels use a fixed-frequency clock, options are limited. You can’t switch out for a faster microcontroller
and expect substantially different results.
One option is to use a different LED type, such as our DotStar or LPD8806 strips, or WS2801 pixels. These can be
driven at higher data rates, though they do have some other tradeoffs with respect to NeoPixels (cost, color
resolution and/or pixel density).
Another is to develop your own code on a more capable microcontroller or an FPGA that drives
multiple NeoPixel
strips
in parallel. One such project — OctoWS2811 for the Teensy 3 microcontroller — is shown later. This sort of thing
is a complex undertaking and not recommended for beginners. And even among more experienced programmers,
there’s often an unreasonable over-emphasis on data rates when the
real bottlenecks lie elsewhere…don’t dwell on
this too much unless you can confirm it’s the root of the problem.
