Turn on neopixel with pause

gringo

Hello,
is it possible to display a running light with neopixels?

Regards
Lars

@gringo
Can you explain in more detail what you want to do?
If you mean can you set a neopixel according to the state of the printer then yes you can by using daemon.g and monitoring state.status in the object model
For example

if state.status = "paused"
   M150 X2 R255 U0 B0 P255 S1 F1
elif state.status = "processing"
   M150 X2 R0 U0 B0 P255 S1 F1
elif state.status = "idle"
   M150 X2 R255 U255 B255 P255 S1 F1
else
   M150 X2 R0 U0 B0 P0 S1 F1

Thanks Owen,
I have 58 neopixels under my printer and I would like to switch them on one after the other.
So first neopixel 1, short pause, switch on neopixel 2, short pause, switch on neopixel 3 and so on.
At the end all 58 neopixels are on.
If this is the case, Neopixel 1 should be switched off after a short pause, then switch off Neopixel 2, short pause, then switch off Neopixel 3 and so on. Until all neopixels are off.
Then start all over again as long as the print is running.

Can I do something like that ?

I have another question about the while loop.
How do I have to write the while loop in daemon.g to make the pass every 2 seconds?
I have read the documentation but do not understand it.

OwenD

@gringo
OK, I think I understand what you want.
I don't have a neopixel, so this is untested.
Try this in daemon.g
I have attached the file to ensure you get the indenting correct as copy/paste sometimes screws it up

You can change any of the settings for colours by sending for example
set global.rLED = 127 from the command line
same for the delay

Because it's in an endless loop, you need a way to abort the daemon in case you need to modify it or just stop it.
Do this by sending set global.runDaemon = false

; 0:/sys/daemon.g


if !exists(global.runDaemon)
	global runDaemon = true
	
if global.runDaemon = false ; send "set global.runDaemn = false" to stop daemon if needed
	M99 ; exit daemon.  


if !exists(global.ledDelay)
	global ledDelay = 2 ; modify to change delay. 
if !exists(global.rLED)
	global rLED = 255 ; set red value 0 to 255
if !exists(global.gLED)
	global gLED = 0 ; set green value 0 to 255
if !exists(global.bLED)
	global bLED = 0 ; set blue value 0 to 255
if !exists(global.wLED)
	global wLED = 0 ; set red value	0 to 255
if !exists(global.ledBrightness)
	global ledBrightness = 255 ; set brightness value 0 to 255
if !exists(global.ledState)
	global.ledState = 0  ; this will be toggled between 0 and 1 on each loop
	
M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels before we start

while true ; create an endless loop

	if global.runDaemon = false
		M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels
		M99 ; exit daemon.
	if state.status ="processing" ; check if we are printing
		; toggle the LED state at each loop
		if global.ledState = 0
			set global.ledState = 1
		else
			set global.ledState = 0
		
		; loop through all the LED's
		while iterations < 57 ; set to one less than number of LED's in neopixel
			M150 R{global.rLED} U{global.gLED} B{global.bLED} W{global.wLED} P{global.ledState = 1 ? global.ledBrightness : 0} S1 F1     ; set next LED in loop to either brightness or off
			G4 S{global.ledDelay}
		M150 R{global.rLED} U{global.gLED} B{global.bLED} W{global.wLED} P{global.ledState = 1 ? global.ledBrightness : 0} S1 F0     ; set last LED in loop
		G4 S{global.ledDelay}
	else
		M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels if we have stopped printing
		G4 S{global.ledDelay}
		
if state.status !="processing"
	G4 S1 ; if we aren't printing add a delay to give control back to processor

daemon.g

Thanks Owen, I will test it next days.
I like the script of your daemon.g you postet first.
Can you show me on this code how to program the while loop to run daemon.g every 2-3 seconds.

Thanks for your help.

@gringo
The second code I posted does that.
Create a "while true" endless loop and put a G4 S2 in it

gringo

I get this error

Error: Bad command: global.ledState = 0
Warning: both space and tab characters used to indent blocks at/before line 41
Error: in file macro line 46 column 28: meta command: unknown variable 'ledState'

line 46 --> if global.ledState = 0

@gringo said in Turn on neopixel with pause:

I get this error
Error: Bad command: global.ledState = 0

Remove the '.' between "global" and "ledState" at line 23.

Error: in file macro line 46 column 28: meta command: unknown variable 'ledState'

line 46 --> if global.ledState = 0

That's a result of the previous error.

Warning: both space and tab characters used to indent blocks at/before line 41

As it says.

@gringo said in Turn on neopixel with pause:

I get this error

Well I did say it was untested

Error: Bad command: global.ledState = 0

change this

if !exists(global.ledState)
	global.ledState = 0

to this

if !exists(global.ledState)
	global ledState = 0

Warning: both space and tab characters used to indent blocks at/before line 41

I don't see any spaces mixed with tabs on my code.
If you copied and pasted or modified the code you may have introduced some.

If you use an editor like notepad++ or RJ TextEd, you can set it to display spaces and tabs.

Thanks a lot, I will test it today and letting you know what happens

gringo

I´m testing it but all neopixel are shining red . After a while all neopixel turned off.
Can we create a Macro for testing?

OwenD

@gringo
As I said, I don't have a neopixel.
It's possible I have made an error with the M150 calls.
I have modified the code to add some echo commands and fix an error.
Tt seems to do the loops correctly.
Please try this and if the echos are correct but the LED control is wrong then you need to focus on the M150 commands to get the on/off correct

File
daemon.g

@gringo
To update daemon.g you must first rename it to say daemon.g.old
Then upload your new version.
It wouldn't hurt to restart after that.

@gringo
I may have not understood how M150 works correctly.
I was assuming that each command was applied immediatly and the F parameter only represented where the sequence started.
However this piece of information from the documentation suggests that is incorrect and the only F0 commands are applied.
The specified RGB values will be sent to the number of LEDs in the LED strip as specified by the S parameter, pushing the existing colours along the strip. To set all the LEDs the same colour, make the S parameter equal to or a little longer than the number of LEDs in the strip

Based on that, try this code instead

; 0:/sys/daemon.g


if !exists(global.runLED)
	global runLED = true
	
if global.runLED = false ; send "set global.runLED = false" to stop daemon if needed

Only the first Neopixel turns on. The display shows me counts of cylces and the count of enabled Neopixel.
In the first pass of all 58 neopixels, only the first one lights up. it is counted up to 56, then the first neopixel goes out again and stays out. It counts up to 56 again and then it starts all over again

OwenD

@gringo
Ok
I'm clearly not up with M150 so hopefully someone else can help

All I can suggest is changing this

		;loop through all the LED's
		while iterations < global.ledSize - 1 ; set to 1 less than number of LED's in neopixel
			if global.runLED = false
				M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels
				echo "exiting loop"
				break
			if global.ledState = 0
				echo "next LED on " , iterations
				M150 R{global.rLED} U{global.gLED} B{global.bLED} W{global.wLED} P{global.ledBrightness} S1 F0
			else
				echo "Next LED off" , iterations
				M150 R0 U0 B0 W0 P0 S1 F0     ; set next LED in loop to either brightness or off
			G4 S{global.ledDelay}

To this

		;loop through all the LED's
		while iterations < global.ledSize 
			if global.runLED = false
				M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels
				echo "exiting loop"
				break
			if global.ledState = 0
				echo "next LED on " , iterations
				M150 R{global.rLED} U{global.gLED} B{global.bLED} W{global.wLED} P{global.ledBrightness} S{iterations+1} F0
			else
				echo "Next LED off" , iterations
				M150 R0 U0 B0 W0 P0 S{iterations +1} F0     ; set next LED in loop to either brightness or off
			G4 S{global.ledDelay}
