This converter uses AVR's internal pull-up, but it seems to be too weak, in particular when you want to use a long or coiled cable.
|
|
||||||
The external pull-up resistor(1K-10K Ohm) on Data is strongly recommended.

If your keyboard is ISO layout
|
You can select keymap(ansi is default) like this:
|
||||||
|
|
||||||
$ make KEYMAP=iso
|
$ make KEYMAP=[ansi|iso|hasu]

LOCKING CAPSLOCK
|
|
||||||
----------------
|
|
||||||
Many of old ADB keyboards have mechanical push-lock switch for Capslock key and this converter supports the locking Capslock key by default. See README in top directory for more detail about this feature.
|
|
||||||
|
|
||||||
Also you may want to remove locking pin from the push-lock switch to use capslock as a normal momentary switch.

You can change a keymap by editing code of keymap.c like following.
|
You can change a keymap by editing code of keymap_[ansi|iso|hasu|yours].c.
|
||||||
This is a keymap for AEK, however, also used for other keyboards.
|
How to define the keymap is probably obvious. You can find key symbols in common/keycode.h. And see doc/keymap.md for more detail.

|
||||||
If you want to define some keymaps than just one, see hhkb/keymap.c and
|
|
||||||
macway/keymap.c as examples. Keymap(layer) switching may needs a bit of
|
|
||||||
effort at this time.
