# User Space Code for Paul Ewing
|
||||
|
||||
This folder contains my user space code.
|
||||
|
||||
## Key Repeater
|
||||
|
||||
I've implemented a key repeater utility in [./key_repeater.h](./key_repeater.h)
|
||||
and [./key_repeater.c](./key_repeater.c) that is similar in concept to the
|
||||
"rapid fire" feature many game controllers come with. The intent behind this is
|
||||
that the user can hold down a key and while it is pressed, a keycode will be
|
||||
repeatedly sent. I have found this useful in certain games and during game
|
||||
development.
|
||||
|
||||
The duration of the key press as well as the time between key presses is
|
||||
slightly randomized by design. This is to simulate more realistic human
|
||||
behavior. By setting the minimum and maximum duration fields to the same value
|
||||
in the configuration, this randomization can be disabled.
|
||||
|
||||
**Note:** Please be aware that this might be against the terms of service in
|
||||
certain games so use your own discretion before using this feature.
|
||||
|
||||
### How to Use
|
||||
|
||||
Define the repeater and then configure and allocate it in your keymap's
|
||||
initialization process:
|
||||
|
||||
```c
|
||||
static struct key_repeater_t* click_repeater = NULL;
|
||||
|
||||
void keyboard_post_init_user(void) {
|
||||
// Seed the random number generator which is used by the key repeater
|
||||
srand(timer_read32());
|
||||
|
||||
// Configure and instantiate a key repeater for mouse button 1 "rapid fire"
|
||||
struct key_repeater_config_t cfg = {
|
||||
.key = KC_BTN1, // Press mouse button 1 (Left click)
|
||||
.key_duration_min = 20, // Press key for 20 to 50 milliseconds
|
||||
.key_duration_max = 50,
|
||||
.wait_duration_min = 90, // Wait for 90 to 140 milliseconds before pressing again
|
||||
.wait_duration_max = 140,
|
||||
};
|
||||
|
||||
click_repeater = kr_new(&cfg);
|
||||
}
|
||||
```
|
||||
|
||||
Make sure the key repeater is polled during matrix scanning:
|
||||
|
||||
```c
|
||||
void matrix_scan_user(void) {
|
||||
kr_poll(click_repeater);
|
||||
}
|
||||
```
|
||||
|
||||
Define a custom keycode that will enable/disable the repeater:
|
||||
|
||||
```c
|
||||
enum {
|
||||
RP_BTN1 = SAFE_RANGE, // Click repeatedly while key is held
|
||||
};
|
||||
```
|
||||
|
||||
Assign the keycode to a key in your `LAYOUT(...)` macro.
|
||||
|
||||
Define the logic to enable/disable the repeater when the custom keycode is
|
||||
pressed or released:
|
||||
|
||||
```c
|
||||
bool process_record_user(uint16_t keycode, keyrecord_t *record) {
|
||||
switch (keycode) {
|
||||
case RP_BTN1:
|
||||
if (record->event.pressed) {
|
||||
kr_enable(click_repeater);
|
||||
} else {
|
||||
kr_disable(click_repeater);
|
||||
}
|
||||
return false;
|
||||
default:
|
||||
return true;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

||||
