You can search within the repository with a search term like ACTION_TAP_DANCE_FN or ACTION_TAP_DANCE_FN_ADVANCED to see more possible uses of these functions.

The goal of the QMK software project is to develop a completely customizable, powerful, and enjoyable firmware experience for any project - keyboard or otherwise - and to provide helpful, encouraging, and kind support and feedback for people with any software development experience. These custom keycodes when pressed, trigger a function that passes the hexcodes. For now, we will keep this at 1 to focus on just getting a “Q and Z to A” combo working, and then add more later. The keycodes MT(mod, kc) and LT(layer, kc) only support basic keycodes. Once satisfied with the custom layout, press Ctrl+X then Y to save and close nano. Simple enough, now the macropad has simple functionality and has been filled up with reaction emojis. How do I access the other pins on my MCU for non-QMK purposes? Here is some background to this issue: a pull request by dpapavas and this thread by Fin_Complete on Reddit. There exist many keymaps within QMK itself, added by users like you and I. QMK question: tap/hold, like LT(), with normal keycodes? These are keycodes such as KC_A, KC_1, and KC_LCTL, which are basic keys defined in the USB HID specification. On this page we have documented keycodes between 0x00FF and 0xFFFF which are used to implement advanced quantum features. I use LT() to switch to a layer when holding a key, and pressing a normal key when tapping, but is this possible with both normal keys? QMK deep dive with sweet16. 8 comments Closed ... not just because of 3. above, but also because QMK internally constrains what keycodes it actually emits over the wire.

For most customizations, you can use the online configurator to make your changes right in the browser. QMK Firmware. Keycodes are defined in the drashna.h file and need to be included in the keymap.c files, so that they can be used there. This is done simply below Simple enough, now the macropad has simple functionality and has … QMK Configurator is an online tool used for easily creating firmware files for keyboards supported in qmk_firmware This is done simply below. The struct is defined in qmk_firmware\quantum\process_keycode\process_tap_dance.h. Custom mechanical keyboards and macropads. These custom keycodes when pressed, trigger a function that passes the hexcodes.
