Welcome to Chief Delphi Forums!

The test code for all of the Vex sensors (including the ultrasonic sensor) for EasyC is located by default in the following directory when EasyC is installed.

C:\Program Files\Intelitek\easyC\Projects\Test Code

Inside this folder should be a file named ULTRASONICTEST.ECP. This file contains the sample code used to run the Ultrasonic sensor. Here is basically what is contained in that file:

#include "UserAPI.h"

int ultrasonic; 

void main ( void )
{
      //Connect Input Wire to Digital Output 11
      //Connect Output wire to Interrupt 1
      //Near = 2, Far = 100
      StartUltrasonic ( 1 , 11 ) ; // interrupt 1= output label on sensor, DO11=input label on sensor
      while ( 1 )
      {
            ultrasonic = GetUltrasonic ( 1 , 11 ) ;
            PrintToScreen ( "ultrasonic =%d\n" , (int)ultrasonic ) ;
      }
}
