Detailed Description

Library for the SRF02 Ultrasonic Ranger Sensor, using the I2C bus for the comunication.

Remeber that sensor can function in serial mode if MODE pin is connected to the ground, but this libary not support this mode.

Example: 

  // Continuously measuring range
  #include "mbed.h"
  #include "SRF02.h"
  // Create instance of class SRF02 for device at address 0xE0 and take mesure in cm
  SRF02 srf02(p28, p27, 0xE0, 0x51);
  DigitalOut led1(LED1);
 
  int main() 
  {
      led1=1;
      while(1)
      {
          printf("Measured range : %.2f cm\n\r",srf02.read());
          wait(0.5);
          led1=!led1;
      }
  }
