IdleLEDs
Having LED effects on the keyboard can be exceptionally helpful. However, having the effects - or lights, in general - on all the time, even when the keyboard is otherwise idle, is perhaps not the best. When one leaves the keyboard, locks the computer, what use are the LED effects then?
One could turn them off manually, but... that's too easy to forget, and why do something the firmware could do for us anyway? What if the LEDs turned themselves off after some configurable idle time? Say, if one did not press any keys for the past ten minutes, just shut 'em off.
This is exactly what the IdleLEDs
plugin does.
Using the plugin
The plugin comes with reasonable defaults (see below), and can be used out of the box, without any further configuration:
#include <Kaleidoscope.h>
#include <Kaleidoscope-LEDControl.h>
#include <Kaleidoscope-LEDEffect-Rainbow.h>
#include <Kaleidoscope-IdleLEDs.h>
KALEIDOSCOPE_INIT_PLUGINS(LEDControl, IdleLEDs, LEDEffectRainbowWave);
void setup (void) {
Kaleidoscope.setup ();
}
Because the plugin needs to know about key events, it is best to make it one of the first plugins, so it can catch all of them, before any other plugin would have a chance to consume key events.
It is also possible to enable run-time configuration via he Focus
plugin, and
persistent storage of such settings. To do that, one has to use the
PersistentIdleLEDs
object instead, provided by the plugin:
#include <Kaleidoscope.h>
#include <Kaleidoscope-LEDControl.h>
#include <Kaleidoscope-LEDEffect-Rainbow.h>
#include <Kaleidoscope-EEPROM-Settings.h>
#include <Kaleidoscope-FocusSerial.h>
#include <Kaleidoscope-IdleLEDs.h>
KALEIDOSCOPE_INIT_PLUGINS(
EEPROMSettings,
Focus,
LEDControl,
PersistentIdleLEDs,
LEDEffectRainbowWave
);
void setup (void) {
Kaleidoscope.setup ();
}
Plugin Properties
The plugin provides two objects, IdleLEDs
, and PersistentIdleLEDs
, both with
the following properties and methods.
.idle_time_limit
Property storing the amount of time that can pass without a single key being pressed before the plugin considers the keyboard idle and turns off the LEDs. Value is expressed in milliseconds.
Defaults to 600000 milliseconds (10 minutes).
Provided for compatibility reasons. It is recommended to use one of the methods below instead of setting this property directly. If using
PersistentIdleLEDs
, setting this property will not persist the value to storage. Use.setIdleTimeoutSeconds()
if persistence is desired.
.idleTimeoutSeconds()
Returns the amount of time (in seconds) that can pass without a single key being pressed before the plugin considers the keyboard idle and turns off the LEDs.
.setIdleTimeoutSeconds(uint32_t new_limit)
Sets the amount of time (in seconds) that can pass without a single key being pressed before the plugin considers the keyboard idle and turns off the LEDs.
Setting the timeout to 0 will disable the plugin until it is set to a higher value.
Focus commands
The plugin provides a single Focus command, but only when using
the PersistentIdleLEDs
variant:
idleleds.time_limit [seconds]
Sets the idle time limit to
seconds
, when called with an argument. Returns the current limit (in seconds) when called without any.Setting the timeout to 0 will disable the plugin until it is set to a higher value.
