    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....

    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...

    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...

    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....
