BSCECTransmitter

For more information about available methods, refer to the roCecInterface entry. Note that you can only use this JavaScript class to send CEC messages. Use BSCECReceiver to receive CEC messages.

When possible, JavaScript APIs should be used instead of BrightScript-Javascript Objects. The JavaScript API equivalent to this object is cec.

Methods

boolean SendRawMessage(in ArrayBuffer data)

boolean SendRawMessage(in ArrayBufferView data)

boolean SendRawMessage(in DOMString data)

void Close()

Shuts down the instance, preventing it from further consuming resources. If this method is not called, garbage collection determines when the instance will be destroyed.

Example

The following JavaScript example shows how to send a set of CEC messages:

function cecDisplayOn()
    {
        console.log("### cecDisplayOn ###");
        var cec_control = new BSCECTransmitter();
        var buffer = new Uint8Array(2);
        buffer[ 0 ] = 0x40;
        buffer[ 1 ] = 0x0D;
        cec_control.SendRawMessage(buffer);
    }

function cecDisplayOff()
    {
        console.log("### cecDisplayOff ###");
        var cec_control = new BSCECTransmitter();
        var buffer = new Uint8Array(2);
        buffer[ 0 ] = 0x40;
        buffer[ 1 ] = 0x36;
        cec_control.SendRawMessage(buffer);
    }
