Seems I forgot to actually include an API proposal.
Something like:
dictionary LEDPatternItem {
DOMString color; // empty string means "off"
int duration; // milliseconds
}
interface LEDManager {
readonly attribute string[] colors; // array of colors the hardware supports
setPattern(sequence<LEDPatternItem> pattern);
}
One assumption here is that we can set a blinking pattern even though
the CPU is put to sleep. Is that generally the case? Or can you only
set a colored pattern? Or a pattern with driver/hardware defined time
slices?
