Scroll Lock and Num Lock support

[theboyknowsclass]

Hi, does anyone know of any way to emulate these keys?

I'm trying to add some extra controls to a KVM and those are quite often used

Looks like they're just scancodes like everything else- https://gist.github.com/MightyPork/6da26e382a7ad91b5496ee55fdc73db2

Caps Lock is already implemented like so:

keybow-firmware/sdcard/keybow.lua

Line 20 in ec9bc99

keybow.CAPSLOCK = 0x39

So maybe:

keybow.NUMLOCK = 0x43
keybow.SCROLLLOCK = 0x47

will work when coupled with the regular key press/release example here:

#67

keybow.set_key(keybow.NUMLOCK, keybow.KEY_DOWN)
keybow.tap_key(...)
keybow.set_key(keybow.NUMLOCK, keybow.KEY_UP)

hi @Gadgetoid - Thanks so much for this! (btw looking at that link NUM_LOCK is 0x53)

weirdly. once I set these and have the following layout - the keybow seems to crash as soon as I hit the scrolllock (it triggers correctly the first time, but after that no keypresses work) - any ideas?

require "keybow"

-- Standard number pad mapping --

-- Key mappings --

function handle_key_00(pressed)
    keybow.set_key(keybow.SCROLLLOCK, pressed)
end

function handle_key_01(pressed)
    keybow.set_key(keybow.NUMLOCK, pressed)
end

anyone else tried this? or can reproduce?
