Javelin Stamp with Devantech SRF02 Sensor

josh_oz

I am having trouble interfacing with the SRF02 sensor. If someone has some experience with this sensor, I would like to know what kind of code I should use to test it.

I have confirmation that the following code works:

// Code for testing SRF02 sensor

import stamp.core.*;
public class test
{
· static final int pinTX = CPU.pin0;
· static final int pinRX = CPU.pin1;
· static Uart srfTX = new Uart(Uart.dirTransmit,pinTX,Uart.invert,Uart.speed9600,Uart.stop2);
· static Uart srfRX = new Uart(Uart.dirReceive,pinRX,Uart.invert,Uart.speed9600,Uart.stop2);

· public static void main()
· {
··· int data;


··· srfTX.sendByte(0x00); //address
····srfTX.sendByte(0x50); //command Real Ranging Mode (result in inches)
··· while(true)
··· {
······· CPU.delay(10500); //wait 1 second
······· srfTX.sendByte(0x00); //address
······· srfTX.sendByte(0x5E); //command Get Range, returns 2 bytes
······· data = srfRX.receiveByte() << 8; //receive MSB
······· data += srfRX.receiveByte();·· //receive LSB
······· System.out.println(data);
···· }
· }
}
