Hello! I am fairly new to beaglebone and all the things that can be done with it.
I recently purchased a neopixel ring light and I was wondering if there were any useful, up-to-date guides on how to drive it from the beaglebone black. I was able to use it easily with arduino, but I have not found a guide on how to use it with beaglebone black, and all the guides that had anything close to it seem to be very much out of date. (Believe me, I have tried following nearly every one that I could find and they do not work at all.)
If there is someone who knows anything about this, I would very much appreciate it
At a guess from the timing requirements you would probably need to program a PRU to do the shifting.
I doubt you would manage it by bitbanging a GPIO line as it is probably done in an Arduino.
Falcon Player ( https://falconchristmas.github.io/ ) supports the various ws281x LED’s (aka: neopixels). On the beagle, it can drive 48 strings (via the PRU’s) directly from the GPIO’s (level shifter recommended). There is also a newer way to drive 128 strings with shift registers.
Caveat: I sell capes for the Beagle specifically designed to do this: https://kulplights.com/
