The `MagicCombo` extension provides a way to perform custom actions when a
|
|
particular set of keys are held down together. The functionality assigned to
|
|
these keys are not changed, and the custom action triggers as long as all keys
|
|
within the set are pressed. The order in which they were pressed do not matter.
|
|
|
|
This can be used to tie complex actions to key chords.
|
|
|
|
## Using the extension
|
|
|
|
To use the extension, we must include the header, create an array of combos we
|
|
want to work with, let the plugin know we want to work with those, and then use
|
|
a special function to handle the combos:
|
|
|
|
```c++
|
|
#include <Kaleidoscope.h>
|
|
#include <Kaleidoscope-MagicCombo.h>
|
|
|
|
static const KaleidoscopePlugins::MagicCombo::combo_t magic_combos[] PROGMEM = {
|
|
{R1C3 | R2C1 | R2C4 | R2C7, // left hand,
|
|
R0C11 | R1C12 | R2C14 //right hand
|
|
},
|
|
{0, 0}
|
|
};
|
|
|
|
void magicComboActions(uint8_t combo_index, uint32_t left_hand, uint32_t right_hand) {
|
|
switch (combo_index) {
|
|
case 0:
|
|
Serial.println("It's a kind of magic!");
|
|
break;
|
|
}
|
|
}
|
|
|
|
void setup() {
|
|
Serial.begin(9600);
|
|
|
|
USE_PLUGINS(&MagicCombo);
|
|
|
|
Kaleidoscope.setup();
|
|
|
|
MagicCombo.magic_combos = magic_combos;
|
|
}
|
|
```
|
|
|
|
The combo list **must** reside in `PROGMEM`, and is a list of tuples. Each
|
|
element in the array has two fields: the left hand state, and the right hand
|
|
state upon which to trigger the custom action. Both of these are bit fields,
|
|
each bit set tells the extension that the key with that index must be held for
|
|
the action to trigger. It is recommended to use the `RxCy` macros of the core
|
|
`KaleidoscopeFirmware`, and *or* them together to form a bitfield.
|
|
|
|
The combo list **must** end with an element containing zero values for both the
|
|
left and the right halves.
|
|
|
|
## Extension methods
|
|
|
|
The extension provides a `MagicCombo` singleton object, with the following
|
|
methods and properties:
|
|
|
|
### `.magic_combos`
|
|
|
|
> Setting this property lets the plugin know which combinations of key presses
|
|
> we are interested in. If any of these are found active, the
|
|
> `magicComboActions()` function will be called.
|
|
|
|
### `.min_interval`
|
|
|
|
> Restrict the magic action to fire at most once every `minInterval`
|
|
> milliseconds.
|
|
>
|
|
> Defaults to 500.
|
|
|
|
## Overrideable methods
|
|
|
|
Whenever an combination is found to be held, the extension will trigger an
|
|
action, in each scan cycle until the keys remain held. This is done by calling
|
|
the overrideable `magicComboActions` function:
|
|
|
|
### `magicComboActions(combo_index, left_hand, right_hand)`
|
|
|
|
> Called whenever a combination is found to be held. The function by default
|
|
> does nothing, and it is recommended to override it from within the Sketch.
|
|
>
|
|
> The first argument will be the index in the combo list, the other two are the
|
|
> key states on the left and right halves, respectively.
|
|
>
|
|
> Plugins that build upon this extensions *should not* override this function,
|
|
> but provide helpers that can be called from it. An override should only happen
|
|
> in the Sketch.
