Halloween Pattern for the 500+ Keyboard LEDs

Quote

I made a Jack O' Lantern inspired color pattern for my Raspberry Pi 500+ keyboard backlight.

The photo's color rendition came out way off, it's standard power button green in the four corners with bright orange for the pumpkin and purple for the cut-outs.

Here's the quick hacked together script I wrote, it draws the pattern then saves it to preset #6. (it is very slow)

Code: Select all

It looks better in person than in your photo. More orange and purple, not red and blue.

European layouts do have a key at 4,1.

Has anyone investigated why this is so slow? I noticed the same issue when i made my function keys orange à la Beeb.

Code: Select all

for i in 0,{1..12}; do
 rpi-keyboard-config led set -c "#ff2000" $i; done
