# 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 == 2) {
|
|
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.
