Mini12864 LCD Color Change

[hopeinformer]

Does anyone know how to change the LCD's backlight color? It's starts up on blue and changes to red, which is good for the typical color of Voron but my build is a dark gray with bright yellow accent parts. Blue or green wouldn't be so bad but I would really like a yellow, or even white.

is it not a menu option?  

LCD MENU -> Lights -> Light Presets -> RED

I was wondering the same thing myself :)

##  To control Neopixel RGB in mini12864 display
pin: EXP1_6
chain_count: 3
initial_RED: 1.0
initial_GREEN: 1.0
initial_BLUE: 1.0
color_order: RGB

That's in the "Displays" section of your Klipper config file; This will give you white RGB = 1,1,1

Thank you. I tried that but for some reason it starts up with the white then after it boots it's right back to red.

I figured it out. The  initial_duration was set to 1 so I changed it to 0 and that did the trick.

Thank you. I had been wondering this myself!.

Thanks all. I benefitted from this thread - my LCD looks much better now

[hopeinformer]

Big time help. Thank you.  1 for red and 1 green then a 0 for blue gave me the yellow I was looking for.

I also found that if you keep the initial_duration to 1 then change these colors below, it also does the trick. INDEX 3 is suppose to be the screen. I preferred to just set the duration to 0 but it's nice to know I can change the color of the knob too.

SET_LED LED=btt_mini12864 RED=1 GREEN=1 BLUE=1 INDEX=1 TRANSMIT=0
SET_LED LED=btt_mini12864 RED=1 GREEN=1 BLUE=0 INDEX=2 TRANSMIT=0
SET_LED LED=btt_mini12864 RED=1 GREEN=1 BLUE=0 INDEX=3

I got my breakout board today for the Mini 12864 - - got up and working but have no clue how to change the colors.

There is no menu option so I presume cfg is the only way.

Here is how its listed on mine... appears all white.

RGB values are expressed as 1 here so 1,1,1 = 256,256,256 RGB

1,0,0 will give pure red
0.5,0.5,0.5 will dim it; at least I assume, that's how I setup mine did it once never looked back  lol

[3dKaosMonkey]

I found it.

 

 

[neopixel]

Neopixel (aka WS2812) LED support (one may define any number of sections with a "neopixel" prefix). One may set the LED color via "SET_LED LED=my_neopixel RED=0.1 GREEN=0.1 BLUE=0.1" type extended g-code commands.

[neopixel my_neopixel]
pin:
#   The pin connected to the neopixel. This parameter must be
#   provided.
#chain_count:
#   The number of Neopixel chips that are "daisy chained" to the
#   provided pin. The default is 1 (which indicates only a single
#   Neopixel is connected to the pin).
#color_order: GRB
#   Set the pixel order required by the LED hardware. Options are GRB,
#   RGB, BRG, GRBW, or RGBW. The default is GRB.
#initial_RED: 0.0
#initial_GREEN: 0.0
#initial_BLUE: 0.0
#initial_WHITE: 0.0
#   Sets the initial LED color of the Neopixel. Each value should be
#   between 0.0 and 1.0. The WHITE option is only available on RGBW
#   LEDs. The default for each color is 0.

@3dKaosMonkey are you going to hold a build diary?

[3dKaosMonkey]

I did start one but still do not have my printed parts.  So I have been trying to get the Pi and Board set up and working.. at least to get familiar but really cannot do much other than power it up.
