As I start to look online for resources for pixel animation planning, I find one inadvertently on the Adafruit Learning Center for animating NeoPixels using bitmaps.
Which is literally, exactly what I'm trying to figure out this second. Except I'm using C++, which is an extra wrinkle. Still, really useful read.
I wonder, would it be easier to design the animation bitmap if I used the horizontal axis for time, instead of the vertical axis?
It would be an interesting scripting challenge.
