Neopixels on toolboard not working correctly

niocio01

My (Duet3 MB6HC in SBC mode) machine is running the latest firmware (3.5.2) which now supports multiple Neopixels, even on Toolboards.

I've tried to hook up a small strip of RGBW neopixels to the "io0.out" ports on one of my toolboards (v1.1)
It's configured and controlled as follows:

M950 E1 C"100.io0.out" T2        ; Neopixels on toolboard 1
M150 E1 R255 P50 S1              ; First led faint red

It turns on, but its full white instead of the expected faint red.
I cannot change it in any way after that, even turning it off (M150 E1 P0 S1) doesn't work.
I can also turn on additional LED's on the strip (using the S parameter), but they are all white and unresponsive after that.

I've used the same LED's connected to the strip that is controlled by the mainboard without problem, so the LED's aren't the problem.

Is there something that I'm missing here?

@niocio01 they are currently broken on toolboards and it's already been raised as an issue on github https://github.com/Duet3D/RepRapFirmware/issues/1018

Yes, this seems to be the exact issue I'm having.

Is there a estimate when this will get fixed?

@niocio01 I've not heard anything at the moment. Most work has been going into the new input shaping for 3.6 on both mainboards and expansion boards
