Dotstar questions?
-
@dc42 Thanks David.
The ground is definitely commoned.
I'll add the resistors as per your suggestion.
Would the firmware changes be added just for this project ? Or, does it need to be added to the features 'wishlist' for Duet 2 firmware ?
How would this be operated in terms of G code ? with M150 command ?
Also, assume that if a thermocouple board is used, only 2 of the CS would be available anyway ?
Thanks,
Keith

if you do ahead with this then I will enable DotStar support in RRF3. It will need a new configuration command (probably a variant of M150) to specify which CS line to use.

Yes.

Yes. So you might want to omit the jumper block and just wire it to use CS1. If you stack it on top of a daughter board then it would use CS3 instead automatically, because CS3 feeding into the daughter board is routed to the corresponding pin for CS1 on the top connector.

I'm going ahead with it.
Jumpers removed.
CS is set to CS_1.
Tank Capacitor value changed, and resistors added as per your suggestion.Just waiting on an assembly price from Chinese supplier.
I'd like to send you a few boards to test with the firmware. ( Take this offline and get address etc via pm ?? )
Thanks

Any updates on the project so far? I'd be interested in the schematics for the board

Is it possible to skip some LEDs in the settings?
Lets say LEDs 1-10 are set to different colors.
I want to change LED2 without changing LED1. -
@cando415 no, just send the same setting again for the LEDS who do not change.
-
can you store that info somewere? which LED should get what state?

Possibly as a variable

@phaedrux
Oh! I have to upgrade my knolagebase!
That makes it much better.
Thx -
@phaedrux
is there a good tutorial for the metacommands somewere? -
I'm not aware of a tutorial, but between the wiki page and the meta command forum section you can find some examples and ask questions.
