IR Remote Control Input

For the specific logic of an application (games for example), binding the remote control inputs can be helpful. Only a subset of all remote control keys is supported on the specific device. Only numerical digits are guaranteed to be supported. This feature must be tested by users on real devices.

Event onKeyUp()

Parameters

Parameters	Type	Required	Description	Supported Since
event (in listener)	Object	Yes	Plain JS object containing keyCode as number and keyName as string and type of event (always keyup string)	1.3.0

Javascript syntax

await sos.input.onKeyUp((keyUpEvent) => {
  console.log(`Pressed: ${keyUpEvent.keyCode} (${keyUpEvent.keyName})`);
});

Map of keyCodes:

Name	Key code	Name	Key Code
UNKNOWN	0	OK	15
NUM_0	1	YELLOW	16
NUM_1	2	BLUE	17
NUM_2	3	RED	18
NUM_3	4	GREEN	19
NUM_4	5	VOLUME_DOWN	20
NUM_5	6	VOLUME_UP	30
NUM_6	7	POWER	31
NUM_7	8	POWER_OFF	32

NUM_9	10	EXIT	34
ARROW_LEFT	11	RETURN	35
ARROW_UP	12	BACKSPACE	36
ARROW_RIGHT	13	LOCK	37
ARROW_DOWN	14

Usage with Typescript

You can also use all these methods with signageOS TypeScript.

interface IKeyUpEvent {
  type: 'keyup';
  keyCode: number;
  keyName: string;
}
interface IKeyUpEventListener {
  (event: IKeyUpEvent): void;
}
onKeyUp(listener: IKeyUpEventListener): void;
