Software package 3.3beta3 released

[Diamondback]

@siam Interesting, can you post some more detail? I'm about to mess up an ethernet extension cable, but USB might be better for me since the connector is smaller...

[SIam]

@diamondback i use this cable https://www.amazon.de/gp/product/B08BJSK567/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 I cut of the plugs and I crimped it to dupont connectors thats all

[Diamondback]

@siam Any specific pins for specific functions? Or just randomly took what was there?

[SIam]

@diamondback (picture was stolen at wikipedia

Red = 3.3V
Black = GND
Blue = SDA => MOSI
Yellow = SDO => MISO
Green = CS =>CS3
Orange = INT => CS4
Violet = SCL => SCK
White = NC

I see that Duet 2 can now do neopixel LEDs, which is super cool, but how do I wire them up and configure? Which pins should I use?

@phaedrux I saw that but it seems to only be for Duet 3 right? Duet 2 has no NP_LED pins

[Phaedrux]

@thebaseddoge Correct. Duet2 lacks the hardware.

Duet 3 MB6HC supports both DotStar and NeoPixel LED strips. Duet 3 Mini supports NeoPixel only. Duet 2 and Duet Maestro do not support these LED strips directly, but you can use an Arduino to interface them to a Duet.

[TheBasedDoge]

@phaedrux Right, but this line in the 3.3beta3 changelog implies that Duet 2 can now do it. That is where my confusion comes from.

Bit-banged NeoPixel LED strips are supported on Duet WiFi/Ethernet. On these boards RRF will wait stop movement while updating the LED strip, so M150 commands should not be issued while the machine is printing, other than at places where a short pause is acceptable such as at layer change and in the start and end scripts.

@thebaseddoge I think a pin has been enabled for controlling the Neopixels on 12864 displays. But I don’t know if it works outside this use case. Will need some @dc42 guidance.

@droftarts I didn't think the Duet 2 Wifi supported the 12864 either, only the Maestro? Hopefully dc42 can clarify everything.
thanks.

[Print3d]

@dc42 I upgraded and noticed user variables in SBC mode are not showing up. I know integration was pulled in b2 and a fix was in the works for 3.3b3... Is this is a bug or have plans changed for user variable integration in SBC mode?

[dc42]

Global variables appear in the Object Model Explorer in 3.3beta3 but changes to their values are not picked up. That is fixed in the forthcoming 3.3RC1.

@dc42 do you have any more info on this? thank you!

[dc42]

@thebaseddoge these are the pins to use when connecting a 12864 LCD to a Duet WiFi/Ethernet:

constexpr Pin EncoderPinB = PortCPin(7);		// connlcd.3	-> exp2.6
constexpr Pin EncoderPinA = PortAPin(8);		// connlcd.4	-> exp2.8
constexpr Pin LcdNeopixelOutPin = PortDPin(18);	        // connlcd.5	-> exp1.5
constexpr Pin LcdResetPin = PortCPin(28);		// connlcd.6	-> exp1.6
constexpr Pin LcdA0Pin = PortDPin(19);			// connlcd.7	-> exp1.7
constexpr Pin LcdCSPin = PortAPin(25);			// connlcd.8	-> exp1.8
constexpr Pin EncoderPinSw = PortDPin(20);		// connlcd.9	-> exp1.9
constexpr Pin LcdBeepPin = PortDPin(21);		// connlcd.10	-> exp1.10

// Additional spi wiring for FYSETC Mini 12864 display:
// connlcd.2 (gnd)	-> exp1.2
// connsd.1 (+5V)	-> exp1.1
// connsd.2 (gnd)	-> exp2.2
// connsd.3 (SD CS)	-> exp2.7
// connsd.4 (sck)	-> exp2.9
// connsd.5 (mosi)	-> exp2.5
// connsd.6 (miso)	-> exp2.10

Warning! Some displays have the EXP1 and EXP2 connectors the other way round. So don't rely on the exp1 and exp2 pin numbers in the above.

[droftarts]

@dc42 I think the question was what pin to use to control Neopixels independently. Is connlcd.5 always available for Neopixels, or only when a 12864 is connected and defined in config.g?

Ian

[dc42]

The support in RRF is intended for driving the LEDs on 7567 displays, however I think it should work without a display being configured provided that you don't try to use drivers 10 and 11. You will need to level shift the signal from 3.3v to 5V.

@dc42
The RGBW Neopixels don't seem to work in 3.3b3 even though it's in the release notes. Is it not implemented yet or am I doing something wrong?

[dc42]

@nmsmith89, it is implemented. There are new M150 X parameter values for RGBW. I have just updated the documentation at https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M150_Set_LED_colours.

@dc42 I do have a PanelDue 5" display, but i dont have anything on stepper 10/11. so do I just need to use pin 5? what fw config changes are required?
