Keyboard color

[junocomp]

How do I set the entire keyboard to one color instead per key?

With a bash script

brightness=4
red=148
green=0
blue=211
cfg="reset\nbrightness $brightness\n"
key=180
for (( i=0; i<=$key; i++ ))
do
    cfg="${cfg}led $i $red $green $blue\n"
done

sudo /home/allan/.local/bin/ite-829x << LEDs
    $(echo -e $cfg)
LEDs

The bash script is an excellent solution!

I'd like to note that the LED codes are not continuous from 0 to 180, there are some gaps that are apparently unmapped. Sending those commands to the keyboard apparently does nothing so it's probably fine. I have no way to guarantee that though.

Here are the LED codes I obtained from my keyboard:

  0 - 19 	Escape -> PageDown
 32 - 43 	Tilde -> Minus
 45 - 51 	Equals -> KeypadMinus
 64 - 83 	Tab1 -> KeypadPlus1
 96 - 108	CapsLock1 -> SingleQuote
110 - 115	Enter1 -> KeypadPlus2
128      	Shift1
130 - 147	Shift2 -> KeypadEnter1
160 - 165	Ctrl1 -> Spacebar1
169 - 179	Spacebar2 -> KeypadEnter2

102 keys.
114 LEDs.

Bash arrays would be a nice solution. Sequence expansion can be used to populate the array.

declare -a LEDs
LEDs=({0..19} {32..43} {45..51} {64..83} {96..108} {110..115} 128 {130..147} {160..165} {169..179})

cfg="reset\nbrightness $brightness\n"

for LED in "${LEDs[@]}"; do
  cfg="${cfg}led ${LED} ${red} ${green} ${blue}\n"
done

I didn't even know you could declare arrays like that in bash. I will definitely improve my script, thank you!

You know, at some point I had a bash script using Zenity to create a GUI for your driver, but then I spilled coffee on my laptop and the script was gone. But my laptop is back and I will definitely rewrite an UI for it.

@allan-null That's frickin' awesome. When I published this project I never thought I'd have users, let alone other developers building on top of it.

I'd be happy to accept patches if you'd like to contribute. Truth is I develop on my smartphone with Termux now. Haven't used my laptop in a while. This is why I haven't been maintaining this.

@allan-null You should post it when you have made the GUI app, that would be great

@junocomp @matheusmoreira There are a few bugs, but it's mostly ready https://github.com/allan-null/ite-829x-ui
