There is an easier way to drive NeoPixels using code that…

1. is simple to understand
2. easy to change without breaking
3. allows indefinitely long pixel strings
4. addresses the root cause of signal reshaping glitches
5. needs only a trivial amount of memory regardless of string length

Here is a demo of a 1,000+ pixel string being driven by a vintage Arduino DueMillinove at about 30 frames per second…
