A few questions with using WS2812B leds and duet2 wifi

andnosobabin

dc42 said "if you don't have stepper driver 11 connected then you don't need an Arduino, just a fast level shifter (e.g. 74HCT08) to boost the signal to 5V. A limitation is that on the Duet WiFi/Ethernet, using the M150 command to change the lighting will pause movement briefly. This is because there is no dedicated DMA-controlled SPI channel for LED lighting on the Duet WiFi, so the firmware has to disable interrupts while it sends the data to the LED strip.

if im understanding this correctly i would connect my DI to Pin 6) EN 11 (LCD_RS) the vcc to 5v and gnd to ground using a converter. Then what do i put in my config file to call that pin for the M150 command and how do i set it up for however many leds are in the strip?

Thanks

@andnosobabin if using RRF 3.5.0-rc.1 then use M950 with the E parameter to tell RRF which pin drives the LED strip. I don't think WS2812 LEDs are supported on Duet 2 in older firmware versions but I'll check.
