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 { encoder1a, 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 | |||
36 | } | ||
37 | |||
38 | |||
39 | ## Hardware | ||
40 | |||
41 | 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. | ||
