LED Grid

Fast refresh a grid of LEDs.

I have 6, 5M 30LEDs/m WS2812B strips and if connected in a grid that would be 900 LEDs. I haven’t cut my strips yet, I have a 288 LED test strip first. Next would be if you can output a control signal on more than one digital pin at the same time. The Photon controller is 120Hz and there is some direct port access, toggling with pinSetFast() pinResetFast() is faster than my oscilloscope can handle.

They seem to have straightforward timing based on a state machine. It seems like there is a library I can start with.

Any idea on how Oscilloscope rating relates to time divisions?
