WS2811 like led-strip, modifing OctoWS2811

[chriszero]

Hi,

I have some LED strips with TM1829 chips. It's nearly like the WS2811 chips.
I've modified the neopixel lib from Adafruit to work with the TM1829 already.
It's just an inverted waveform of the WS2811.

-___--___--___ <- WS2811
_----_-----_------ <- TM1829

I've swapped the edge detect interrupts (DMAMUX_SOURCE_PORTC <-> DMAMUX_SOURCE_PORTB) But it does not work quite right.
I unfortunately doesn't have a Oscilloscope to check the signal...

You probably need to leave the interrupts the same, but change the DMA destinations, so the sets become clears and vise-versa.

Also, please read these tech question posting guidelines...
