Duet 3 6HC NeoPixel RGBW

[hikkakaru]

Hi there,

Installed RGBW NeoPixel strip on a 6HC before realizing that RGBW support isn't available yet.

They work -- in a way. M150 lights them up in alternating colors from LED to LED and without RGB support. Light intensity works fine.

Is there any kind of hacky way I can get the dotstar/neopixel header working for this? I hadn't realized that only RGB support seems to be in place.

Worst case I can move it to my SBC -- but i'd love to be able to use the M150 gcode without deferring it to the SBC.

Thanks

Just to update : addressing seems to sort of work, intensity adjustment works fine -- the RGB values are just all over the place.

Set all to R255, , LEDs are red/green/blue alternating down the line.

However, they start and stop at the right points along the strip, so addressing is there halfway.

Adding RGBW support is on the firmware wishlist. It doesn't look hard so I will probably do it quite soon, perhaps in time for the 3.2 release depending on how soon that is.

@dc42 That's fantastic.

Thanks so much for your hard work.

I'll keep the RGBWs in just in case the initial release of the RGBW stuff happens sometime soon.

Thanks again.

RGBW Neopixels are now supported in the 3.3 source code, so release 3.3beta3 will support them.
