FPP driving WS2812 pixels with BBB
« on: April 25, 2015, 07:40:19 PM »
Hi Everyone,

Thanks to David Pitts & Captain Murdoch I've successfully driven 5760 WS2812 pixels from 24 outputs on a BBB.  Currently using an RGB123 cape (http://rgb-123.com/product/beaglebone-black-48-output-cape/).

Ignore a couple of issues on my 120x48 matrix, need to do a repair or two.  Previously I had to use 2 x Pixlite16's or 3 or 4 J1Sys P12S's to drive this matrix, so using half a BBB is a big win!

2 strips not working, I probably blew the first pixel in the first string.

Great news about driving 2812 pixels from BBB.

This code is the same Channel Output that is being used to drive the F16-B and F4-B, you just select the 'cape type' during configuration to tell FPP if you have a F16-B, F4-B, or RGBCape48C.   I have also been testing with TM1804 square pixels during development.
