I've been using a LEDscape fork that I think will better allow me to use Python to write the bulk of my program, and then LEDscape to do the Neopixel control.
https://github.com/Yona-Appletree/LEDscape Everything works, except that you should check the uEnv.txt file in /boot or possible /boot/uboot to make sure you've put the *.dtb file in the correct place to be read. Different distros do different things, so it's hard to say exactly what you're looking for here. Unfortunately, USPS is late, so I won't have my Neopixel Stick before I leave this evening, so I won't be putting any time into this over the weekend, but I do expect to pick this back up early next week. -Ian On Friday, April 25, 2014 8:07:55 AM UTC-4, Yoder, Mark A wrote: > > Ian: > What instructions were you following? > > --Mark > > Sent from my iPad > > On Apr 25, 2014, at 7:21 AM, "Ian Woloschin" > <iwolo...@gmail.com<javascript:>> > wrote: > > I'm an idiot.
