Neopixel support on 1LC?

[pixelpieper]

Would it be possible to add neopixel support to the 1LC firmware on IO0? I am aware that I will likely need to add a buffer as a level shifter and that I won’t be able to drive more than maybe three or four pixels, but it would simplify adding lights to the toolhead.

@pixelpieper in theory pin io1.out could be used to drive Neopixels, assuming you are not already using it e.g. for a BLTouch. This pin supports SPI so it could drive a long string without using excessive CPU time. The 5V regulator on the tool board is a linear one powered from the 12V buck regulator, so you would need to use external 5V power unless driving no more than about two LEDs. However, the firmware would need to be extended to support passing Neopixel commands over CAN.

@dc42 That sounds good, I am aware that I anyway would need a small level shifting PCB, so adding a dedicated regulator to not overwhelm the LDO would be fine. I just really dont want more wires in my cable chain

Yep, that would be really great.
The new voron toolhead is coming soon with nozzle lights (and a bling lit logo.)

Would be nice to combine with the 1LC. I need only two max three leds.

@dc42 +1 for me as a future enhancement

You wouldn't need a level shifter, because the outputs of the 1LC have 5V signal levels.

I've added this to the firmware wish list.

Yeah as Gixxer said this is the driver (it equips three RGBW discrete neopixel leds)

Also our Klipper "colleagues" (which always are some meters ahead....of us) already have a tool-board with that supported...
@dc42 Thanks for moving this forward and make it a Christmas gift

Hi @dc42, I know this is probably one of the least important features to implement, but I was still wondering if you have a timeline for this. I suppose it will not come with RRF 3.4?

thanks anyways,
Niklas

@dc42 Had a glance at this in the last 3,5 months?

@oc_geek

Just chiming in to add a +1 for me on this as well. Would be helpful.

Adding a +1 from me. With the new Voron Extruder the Stealthburner hitting RC1, this design is largely finalized and will be released soon. The Duet 6HC & Toolboard combo makes a very good setup for this printer with the features it has. It also eliminates the need to send 20+ wires through 3 x cable chains to the tool head with the can bus. That, and Thomas Sanladerer built his Voron 2.4 with a Duet meaning his 417K subscribers got to see that build. Almost half a million people viewed his Voron videos using a Duet by the stats. I am sure there are a lot of people buying into the Duet ecosystem for this printer just from these videos alone so perhaps if the full Voron 2.4 isn't supported because of neopixels on the tool board then I think there's a compelling reason to add it to the firmware. @dc42 would you have any thoughts on this?

[IndeX4D]

Hey

Any news about it?

[dc42]

@index4d I intend to add this support in firmware 3.5 but probably not in the first beta. See also my post here https://forum.duet3d.com/topic/30027/duet-3-toolboard-1lc-io0-input-output-dual-purpose-neopixel/4?_=1665066620511.

Hi,

would you share the stl from your umbilical-1lc-mount-combination?

Thank you very much,
