On the Teensy LC, what is the best way to drive a string of WS28xx LEDs through pin 17's 5V output with DMA? I want to drive a short string of LEDs, about 10, but I want the CPU to do other things with low latency, not sit around banging bits.
OctoWS2811 does not use pin 17. FastLED does not use DMA (I think).
I could leave pin 17 in high impedance and jumper its 3V pad to another pin that OctoWS does use. Would that work?
Is there a better way?
Thanks.
