PCB board was delivered from China today. I can confirm it working without any glitches for PL9823 leds 128 leds/channel all 32 channels. Not tested anything else, life gets in the way....
Origional problem may have...
Quick test program cycling a rainbow using FlexIO2 pin 8,9 and 10 and 1 or 2 DMA channels depending on the LED type (PL9823 or WS2811).
I have not tested my new board design, but KiCad files are included.

Made a new board, going to flexio2 those pins are closer. Going to test out if I get the software to work before ordering this PCB with assembly, because no way I can solder this by hand anymore....
Hopefully this...
Arrrg i’m way over my head here in the electrical engineering department... I made this 2 layer board and i put ground on top and on bottom layer with a few traces, but there are not many on the top, just 4 cm in total....
This is a copy of the issue on github: I'm working with your lib and so far it's great, thanks for it!
I reached out to you on linkedin during the month of june about some issues and I'd like to thank you for the...
The idea behind this library is fantastic, credits to Ward! But it seems to me there needs to be a little more effort in the coding part.
Like this:

Well, it is still black magic to me, but it seems the pll5 timing and the dma timing is loosly coupled... meaning ifyou adjust the pll5 timing the 4 pieces of dma don’t adjust accross the new range. This might give a...
I have to look into it, but those zero’s are probably the reset. The reset for ws2811 (don’t know sk6812) needs to be at least 280000 ns acording to the datasheet, hook up a scope and verify?. The double buffering in...
I had some problems getting the lib to work, but i resolved it by tweaking the pll5 clock. I’m just posting this here because this beast deserves way more attention than it is currently getting ;)
