From a software standpoint, is it possible for FastSPI2 to drive a single string of 300pixels? (Teensy3.0, WS2811). I know the framerate will drop, but thats OK. The T3.0 has adequate RAM available, but do any internal library variables start to overflow or go crazy when the single-string pixel count goes above a certain value? Thanks! -frenchy
There’s no 8-bit (256) limit on pixels; it all comes down to frame rate and RAM limits.
I helped do a 400-pixel installation for New Year’s, and ran the whole thing off of one (very tired!) Arduino Nano. The animation was simple enough that it didn’t need much RAM for other data structures or a deep stack.
The Teensy3 has plenty of RAM, too. You should be fine!
This is 700 leds on a single Mega. Its FastSPI_LED not the version 2 library but pretty sure there is no limitation. As Mark said its just how fast you can refresh and SRAM limitations…
