Keyboard Config

I've made a number of changes to the firmware of my Keychron K6 Pro, but don't want to be locked down to one specific fork of qmk_firmware.

This board has bluetooth capability, which is only included in the bluetooth_playground branch of Keychron's fork of qmk_firmware.

I prefer Vial to Via because, unlike Via, Vial is open-source and stores a copy of the keymap on the keyboard.

Changes

Rearrange layers and reassign keys in the keyboards/keychron/k6_pro/ansi/rgb/keymaps/default/keymap.c (View a copy of my changes in keymap.c)

Add code that changes which layers the dip switch toggles between in keyboards/keychron/k6_pro/k6_pro.c

bool dip_switch_update_kb(uint8_t index, bool active) {
    if (index == 0) {
        // -------------------THIS IS THE DEFAULT SETTING-------------------
        // Mac/iOS side of switch is layer 0 and Win/Android side of switch is layer 1
        // default_layer_set(1UL << (active ? 1 : 0));

        // -------------------THIS IS MY CUSTOM SETTING-------------------
        // Mac/iOS side of switch is layer 0 and Win/Android side of switch is layer 2
        default_layer_set(1UL << (active ? 2 : 0));
    }
    dip_switch_update_user(index, active);

    return true;
}

Change the TAPPING_TOGGLE value to 2 in quantum/action_tapping.h

Add a tap dance that allows grave/tilda and esc to share a key

Add TAP_DANCE_ENABLE = yes to keyboards/keychron/k6_pro/rules.mk
Define the tap dance in keyboards/keychron/k6_pro/ansi/rgb/keymaps/default/keymap.c if it's not already there

// Tap Dance declaration(s)
enum {
    G_ESC,
};

// Tap Dance definition(s)
qk_tap_dance_action_t tap_dance_actions[] = {
    // Tap once for Escape, twice for Caps Lock
    [G_ESC] = ACTION_TAP_DANCE_DOUBLE(KC_GRAVE, KC_ESCAPE),
};
// Add tap dance item to your keymap in place of a keycode
const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {
    // ...
    TD(G_ESC)
    // ...
};

Add some macros

Define some more keycodes in keyboards/keychron/k6_pro/k6_pro.h

enum {
    KC_LOPTN = USER_START,
    KC_ROPTN,
    KC_LCMMD,
    KC_RCMMD,
    KC_MCTL,
    KC_LNPD,
    KC_TASK,
    KC_FILE,
    KC_SNAP,
    KC_CTANA,
    KC_SIRI,
    KC_USR1,
    KC_PAS1,
    KC_USR2,
    KC_PAS2,
#ifdef KC_BLUETOOTH_ENABLE
    BT_HST1,
    BT_HST2,
    BT_HST3,
#endif
    BAT_LVL,
    NEW_SAFE_RANGE,
};

Define the macro input strings in the beginning of keyboards/keychron/k6_pro/k6_pro.c

#define MACRO_INPUT_1 "Test1"
#define MACRO_INPUT_2 "Test2"
#define MACRO_INPUT_3 "Test3"
#define MACRO_INPUT_4 "Test4"

Add more cases to the switch statement in process_record_kb() in keyboards/keychron/k6_pro/k6_pro.c

case KC_USR1:
    if (record->event.pressed) {
        SEND_STRING(MACRO_INPUT_1);
    }
    return false; // Skip all further processing of this key
case KC_PAS1:
    if (record->event.pressed) {
        SEND_STRING(MACRO_INPUT_2);
    }
    return false; // Skip all further processing of this key
case KC_USR2:
    if (record->event.pressed) {
        SEND_STRING(MACRO_INPUT_3);
    }
    return false; // Skip all further processing of this key
case KC_PAS2:
    if (record->event.pressed) {
        SEND_STRING(MACRO_INPUT_4);
    }
    return false; // Skip all further processing of this key

Make the battery level animation quicker in keyboards/keychron/bluetooth/bat_level_animation.c

#ifndef BAT_LEVEL_GROWING_INTERVAL
#    define BAT_LEVEL_GROWING_INTERVAL 80 // ORIGINALLY 150
#endif

#ifndef BAT_LEVEL_ON_INTERVAL
#    define BAT_LEVEL_ON_INTERVAL 1000 // ORIGINALLY 3000
#endif

Give the customKeycodes better names and titles in the keyboards/keychron/k6_pro/ansi/rgb/keymaps/vial/vial.json

"customKeycodes": [
    {"name": "Left Opt", "title": "Left Option", "shortName": "LOpt"},
