Using a custom *map and changing behavior of lock LEDs

[RaoulDuke-Esq]

Hi Hasu,

I'm loving ibmpc_usb and have been using the online GUI but I'm ready to take it to the next level. I tried creating a keymap_raoulduke-esq.c in my local fork and using make -f Makefile.atmega32u4 [KEYMAP=raoulduke-esq] but it said it could not find the keymap. How do I successfully build the firmware with a custom keymap when the default behavior is to use a unimap?

Once I've got my custom keymap working, I wanted to make my ibmpc devices use the lock lights as layer status indicators (i.e. Layer 0 active = NumLock light on; layer 1 active = CapsLock on, etc.). I use a Mac so numlock doesn't have a role, I don't use Capslock, and there's no scroll lock either so I figured layer lights would let me see these gorgeous green LEDs. Could you give me an example of how to use the a hook with my converter to make this happen?

you need unimap_yourname.c probably.

Thanks! I'll try that and mark as the answer if successful.

Any ideas about the LEDs?

You can use hook_layer_change to know layer state and change indicators.
https://github.com/tmk/tmk_keyboard/blob/master/tmk_core/common/hook.h#L78

Also you may need to override default behaviour using hook_keyboard_leds_change or led_set.

Refer to led_set in ibmpc_usb.c for how to handle the indicators.

There is some discussion about this around this comment.
