Hi Everyone,

I am pretty puzzled, I am trying to test the SRF02 ultrasonic sensor with the serial line, before writing the code to use it with i2c, but it is not working, I cant get a return value! The code is pretty short and tried various things, but I cant find the problem.

I also tried using the i2c library but I get no output either.

void setup(){
  Serial.begin(9600);
}

void loop(){
  Serial.print(0x00,BYTE);
  Serial.print(0x51,BYTE);//start measurement
  delay(1000);/wait
  Serial.print(0x00,BYTE);
  Serial.print(0x5E,BYTE);/read the two bytes value result of the measurement
  delay(1000);
  while(Serial.available()>0){
    int foo = Serial.read();
    Serial.println(foo,DEC);
  }
}

I believe it is something really stupid I am getting wrong but I havent been able to see it.

Thanks.
