Kaleidoscope-HostPowerManagement

Support performing custom actions whenever the host suspends, resumes, or is sleeping. By default, the LEDs will be turned off on suspend, and the previous LED mode restored on resume.

Using the plugin

To use the plugin, one needs to include the header, and activate it. No further configuration is necessary, unless one wants to perform custom actions.

#include <Kaleidoscope.h>
#include <Kaleidoscope-HostPowerManagement.h>

void setup () {
  Kaleidoscope.setup ();

  Kaleidoscope.use(&HostPowerManagement);
  HostPowerManagement.enableWakeup();
}

Plugin methods

The plugin provides the HostPowerManagement object, which has the following methods:

.enableWakeup()

Enables host wakeup support. When enabled, pressing any key on the keyboard will wake the host up.

Once enabled, it cannot be disabled again.

.toggleLEDs(event)

Turns LEDs off on suspend, restores the previous LED mode on resume. This is called by hostPowerManagementEventHandler() by default.

Overrideable methods

hostPowerManagementEventHandler(event)

The hostPowerManagementEventHandler method is the brain of the plugin: this function tells it what action to perform in response to the various events.

Currently supported events are: kaleidoscope::HostPowerManagement::Suspend is fired once when the host suspends; kaleidoscope::HostPowerManagement::Sleep is fired every cycle while the host is suspended; kaleidoscope::HostPowerManagement::Resume is fired once when the host wakes up.

The default implementation calls HostPowerManagement.toggleLEDs. When overriding the function, the default is lost.
