3 Basic encoders are supported by adding this to your `rules.mk`:
7 and this to your `config.h`:
9 #define NUMBER_OF_ENCODERS 1
10 #define ENCODERS_PAD_A { B12 }
11 #define ENCODERS_PAD_B { B13 }
13 Each PAD_A/B variable defines an array so multiple encoders can be defined, e.g.:
15 #define ENCODERS_PAD_A { encoder1a, encoder2a }
16 #define ENCODERS_PAD_B { encoder1b, encoder2b }
18 If your encoder's clockwise directions are incorrect, you can swap the A & B pad definitions.
20 Additionally, the resolution can be specified in the same file (the default & suggested is 4):
22 #define ENCODER_RESOLUTION 4
26 The callback functions can be inserted into your `<keyboard>.c`:
28 void encoder_update_kb(uint8_t index, bool clockwise) {
29 encoder_update_user(index, clockwise);
34 void encoder_update_user(uint8_t index, bool clockwise) {
35 if (index == 0) { /* First encoder */
41 } else if (index == 1) { /* Second encoder
52 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.
