Hi,

I'm trying to make a service for manage infrared remote code, And i need do generate pulse at 38KHz.

I've tryed to do this ( see the code ) , but it's really slow . Can someone give me a method to do that ?

private void sendIr(int period){
		if (irOutIsConnected){
			int time = (int)((1.0 / frequency) * 1000 / 2);
			int currentPeriod = 0;
			while (currentPeriod < period){ 
				try {
					arduino.digitalWrite(irOutPin, 1);
					TimeUnit.MICROSECONDS.sleep(time);
				} catch (InterruptedException e1) {
					// TODO Auto-generated catch block
					e1.printStackTrace();
				}
				try {
					arduino.digitalWrite(irOutPin, 0);
					TimeUnit.MICROSECONDS.sleep(time);
				} 	catch (InterruptedException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				currentPeriod += (2 * time);
				System.out.println("currentPeriod" + currentPeriod);
			}
		}
		else{
			System.out.println("ERROR : IR Out Pin isn't connected !");
		}
	}

Frequency = 38 ( in Khz ), and Period is a int that containt duration of the pulse in microseconds .

So for 38KHz, i must do during the period time, loop "pin high for 13 microseconds, pin low for 13 microseconds"

Thx for your help
