3 Basic encoders are supported by adding this to your `rules.mk`:
7 and this to your `config.h`:
9 #define ENCODERS_PAD_A { B12 }
10 #define ENCODERS_PAD_B { B13 }
12 Each PAD_A/B variable defines an array so multiple encoders can be defined, e.g.:
14 #define ENCODERS_PAD_A { encoder1a, encoder2a }
15 #define ENCODERS_PAD_B { encoder1b, encoder2b }
17 If your encoder's clockwise directions are incorrect, you can swap the A & B pad definitions.
19 Additionally, the resolution can be specified in the same file (the default & suggested is 4):
21 #define ENCODER_RESOLUTION 4
25 If you are using different pinouts for the encoders on each half of a split keyboard, you can define the pinout for the right half like this:
28 #define ENCODERS_PAD_A_RIGHT { encoder1a, encoder2a }
29 #define ENCODERS_PAD_B_RIGHT { encoder1b, encoder2b }
34 The callback functions can be inserted into your `<keyboard>.c`:
36 void encoder_update_kb(uint8_t index, bool clockwise) {
37 encoder_update_user(index, clockwise);
42 void encoder_update_user(uint8_t index, bool clockwise) {
43 if (index == 0) { /* First encoder */
49 } else if (index == 1) { /* Second encoder */
60 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.
