 | # Encoders
Basic encoders are supported by adding this to your `rules.mk`:
    ENCODER_ENABLE = yes
and this to your `config.h`:
    #define NUMBER_OF_ENCODERS 1
    #define ENCODERS_PAD_A { B12 }
    #define ENCODERS_PAD_B { B13 }
Each PAD_A/B variable defines an array so multiple encoders can be defined, e.g.:
    #define ENCODERS_PAD_A { encoder1a, encoder2a }
    #define ENCODERS_PAD_B { encoder1a, encoder2b }
If your encoder's clockwise directions are incorrect, you can swap the A & B pad definitions.
Additionally, the resolution can be specified in the same file (the default & suggested is 4):
    #define ENCODER_RESOLUTION 4
## Callbacks
The callback functions can be inserted into your `<keyboard>.c`:
    void encoder_update_kb(uint8_t index, bool clockwise) {
        encoder_update_user(index, clockwise);
    }
or `keymap.c`:
    void encoder_update_user(uint8_t index, bool clockwise) {
        if (index == 0) {
            if (clockwise) {
                register_code(KC_PGDN);
                unregister_code(KC_PGDN);
            } else {
                register_code(KC_PGUP);
                unregister_code(KC_PGUP);
            }
        }
    }
## Hardware
The A an B lines of the encoders should be wired directly to the MCU, and the C/common lines should be wired to ground.
