The `Heatmap` plugin provides a LED effect, that displays a heatmap on the
|
|
keyboard. The LEDs under each key will have a color according to how much use
|
|
they see. Fewer used keys will have deep blue colors, that gradually turns
|
|
lighter, then green, to yellow, and finally red for the most used keys. The
|
|
heatmap is not updated on every key press, but periodically. It's precision is
|
|
also an approximation, and not a hundred percent exact. Nevertheless, it is a
|
|
reasonable estimate.
|
|
|
|
## Using the plugin
|
|
|
|
The plugin comes with reasonable defaults pre-configured, all one needs to do is
|
|
include the header, and make sure the plugin is in use:
|
|
|
|
```c++
|
|
#include <Akela-Heatmap.h>
|
|
|
|
void setup (void) {
|
|
Keyboardio.setup (KEYMAP_SIZE);
|
|
Keyboardio.use (&HeatmapEffect, NULL);
|
|
}
|
|
```
|
|
|
|
This sets up the heatmap to update every 500 cycles, which is about 2.5 seconds,
|
|
and is the default. It also registers a new LED effect, which means that if you
|
|
have not set up any other effects, then Heatmap will likely be the default. You
|
|
may not want that, so setting up at least one other LED effect, such as `LEDOff`
|
|
is highly recommended.
|
|
|
|
## Plugin methods
|
|
|
|
The plugin provides two methods on the `HeatmapEffect` object:
|
|
|
|
### `.configure(updateFrequency)`
|
|
|
|
> Sets up the update frequency of the heatmap. The smaller this value is, the
|
|
> more often the heatmap gets updated, but that comes with a cost: updating the
|
|
> heatmap takes a fairly large amount of computation, and is not fast. Doing it
|
|
> often will considerably slow down the keyboard, and that is rarely a desirable
|
|
> thing.
|
|
>
|
|
> Nevertheless, the frequency preferred is a very subjective thing, which is why
|
|
> this function exists. Give it a number, and it will wait that many scan cycles
|
|
> between updates.
|
|
>
|
|
> Defaults to *500*.
|
|
|
|
### `.activate()`
|
|
|
|
> When called, immediately activates the Heatmap effect. Mostly useful in the
|
|
> `setup()` method of the Sketch, or in macros that are meant to switch to the
|
|
> heatmap effect, no matter where we are in the list.
