Beagleboard's come with PRUs, for which, if you need a lot of very fast GPIO, there's no substitute. I've driven 9000 LEDs at 100fps with Octoscroller

- blacksmith_tb 10y agoWhich is admittedly very cool, for some applications - but the PRUs can't account for the huge price difference by themselves, I wouldn't think.
- hackcasual 10y agoIt's more of a case that is a niche feature, so only pricier chips include it.
- jwatte 10y agoJust use one of the for cores on a rpi2 locked to GPIO duty and you can run them as fast as you want...
- sigkill 10y agoI've heard this mentioned before in the passing. How does one actually do this.
