-# 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 { encoder1b, 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) { /* First encoder */
- if (clockwise) {
- tap_code(KC_PGDN);
- } else {
- tap_code(KC_PGUP);
- }
- } else if (index == 1) { /* Second encoder
- if (clockwise) {
- tap_code(KC_UP);
- } else {
- tap_code(KC_DOWN);
- }
- }
- }
-
-## 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.
