| 1 | # Encoders | ||
| 2 | |||
| 3 | Basic encoders are supported by adding this to your `rules.mk`: | ||
| 4 | |||
| 5 | ENCODER_ENABLE = yes | ||
| 6 | |||
| 7 | and this to your `config.h`: | ||
| 8 | |||
| 9 | #define NUMBER_OF_ENCODERS 1 | ||
| 10 | #define ENCODERS_PAD_A { B12 } | ||
| 11 | #define ENCODERS_PAD_B { B13 } | ||
| 12 | |||
| 13 | Each PAD_A/B variable defines an array so multiple encoders can be defined, e.g.: | ||
| 14 | |||
| 15 | #define ENCODERS_PAD_A { encoder1a, encoder2a } | ||
| 16 | #define ENCODERS_PAD_B { encoder1b, encoder2b } | ||
| 17 | |||
| 18 | If your encoder's clockwise directions are incorrect, you can swap the A & B pad definitions. | ||
| 19 | |||
| 20 | Additionally, the resolution can be specified in the same file (the default & suggested is 4): | ||
| 21 | |||
| 22 | #define ENCODER_RESOLUTION 4 | ||
| 23 | |||
| 24 | ## Callbacks | ||
| 25 | |||
| 26 | The callback functions can be inserted into your `<keyboard>.c`: | ||
| 27 | |||
| 28 | void encoder_update_kb(uint8_t index, bool clockwise) { | ||
| 29 | encoder_update_user(index, clockwise); | ||
| 30 | } | ||
| 31 | |||
| 32 | or `keymap.c`: | ||
| 33 | |||
| 34 | void encoder_update_user(uint8_t index, bool clockwise) { | ||
| 35 | if (index == 0) { | ||
| 36 | if (clockwise) { | ||
| 37 | register_code(KC_PGDN); | ||
| 38 | unregister_code(KC_PGDN); | ||
| 39 | } else { | ||
| 40 | register_code(KC_PGUP); | ||
| 41 | unregister_code(KC_PGUP); | ||
| 42 | } | ||
| 43 | } | ||
| 44 | } | ||
| 45 | |||
| 46 | ## Hardware | ||
| 47 | |||
| 48 | 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. | ||
