Any way to make Morse Code output to an LED on a keyboard?

2

As in make the capslock or scroll lock or some other led on a keyboard flash?

Currently, dietpi-morsecode uses /sys/class/leds/led0 and /sys/class/leds/led1, on most SBCs power and activity LEDs. Some keyboards use such sysfs device as well, which would then be easy to implement by allowing to define the devices which should be toggled. However, most keyboard LEDs cannot be toggled via sysfs, in which case best would be to allow entering custom “turn on” and “turn off” commands, or flashing the mostly available capslock or numlock LEDs via setleds or numlockx commands.

If someone has some shell experience, it shouldn’t be too hard to implement new modes here, extending the Output_On and Output_Off functions: DietPi/dietpi-morsecode at dev · MichaIng/DietPi · GitHub

Yes, it’s definitely possible if the keyboard allows LED control through software or firmware. Some people use Arduino, QMK firmware, or small scripts to blink Caps Lock or RGB LEDs in Morse patterns. It can actually be a fun way to practice Morse visually instead of only using sound.

I tested something similar while experimenting with the best Morse code-related, and syncing light flashes with dots and dashes worked surprisingly well for learning timing.
