Well, I've just downloaded the Ultrasonic library for the HC-SR04: http://iteadstudio.com/produce/cheap-cheap-ultrasonic-ranging-modulehc-sr04/
And in Arduino 022 it compiles perfectly with no errors, but when using the library in Arduino 1.0 I get this error:
In file included from UltrasonicDemoMod.cpp:1:
D:\Programming\Arduino\Arduino\libraries\Ultrasonic/Ultrasonic.h:11:22: error: WProgram.h: No such file or directory
My project code is the following:
#include "Ultrasonic.h"
Ultrasonic ultrasonic(12,13);
void setup()
{
Serial.begin(9600);
Serial.print("testing...");
}
void loop()
{
Serial.print(ultrasonic.Ranging(CM));
Serial.println(" cm.");
delay(100);
}
How come WProgram.h is no more in Arduino 1.0? or maybe it has been renamed?
