Solved Dotstar duet3 problem

[tom33]

Hi,
I order dotsar led from adafruit (https://www.adafruit.com/product/2237?length=2). When I send a command nothing appened.
I try M150 R255 F1 Y30 and M150 R255 P128 S20 F1 for exemple

I have the M150 X0 Q3000000 in the config files for configuring the led

I use RRF 3.2.2 and duet 3MB6HC

@tom33, I will re-test DotStar LEDs on Duet 3, probably tomorrow.

@tom33, I confirm that the DotStar driver was not working. I have now fixed it. The fix will be in the 3.3beta3 release. A preview 3.2beta2+ build including the fix is available at https://www.dropbox.com/sh/dupd9u1xppr1om5/AADYg4guuj2n8LJokVqtK-C7a?dl=0.

@dc42,
The led works well now thanks !
And do you know if is it possible to make them blink during printing for example ?

Yes, using either commands embedded in the GCode you are printing, or commands in the daemon.g file.

@dc42 I'm happy to report - this also fixes the problem with mini 12864.

Hi. I also have the Dotstar LED-strip. But its not working with Firmware 3.3.0
Any ideas why?

I tryed to use
M150 X1
M150 R255 P128 S20 F1
and
M150 X0
M150 R255 P128 S20 F1
both without any red LED

Nr. 1 is white. but i can't change anything

@cando415 have you checked the connections? Unfortunately the pinouts are not standard for DotStar strips, neither are the colours. The +5V and ground connections are usually easy to identify, but the clock and data inputs may be either way round.

Thanks. My Fault. Dotstar on Dotstarconnection. Didn't check the wiring
