Hi all,

I have the Elapsed Timer library for Arduino 022 and my program works great.
However it will not work in version 1.02, I get the following error messages.
Can anyone point me to the updated library or a fix ?

C:\Users\Denis\arduino-1.0.2\libraries\Elapsed\Elapsed.cpp: In member function 'void Elapsed::reset()':
C:\Users\Denis\arduino-1.0.2\libraries\Elapsed\Elapsed.cpp:52: error: 'micros' was not declared in this scope

Where did you get this library, which does not appear to have been updated for 1.0?

Here is a little class I use to time stuff,
its template parameter is  'true' for high resolution ( micros ), or false for low ( millis ).

Code:

template< bool _HiRes = true >
  class TimeThis{
    protected:
      typedef TimeThis< _HiRes > MYTYPE;
      inline static const unsigned long GetTime( void )  { return ( _HiRes ? micros : millis )(); }
    public:
      TimeThis( unsigned long &u_TimeRef ) : u_Time( u_TimeRef = MYTYPE::GetTime() )  { return; }
      ~TimeThis( void )  { this->u_Time = MYTYPE::GetTime() - this->u_Time; }
    private:
      unsigned long   &u_Time;
};

void loop(){

    unsigned long u_Time;
    {
      TimeThis< true > t_Time( u_Time );
      
      //Lengthy operation
    }
    Serial.print( "Run Time: " );
    Serial.println( u_Time );
}

void setup(){Serial.begin(9600);}

Looks like it might be one of mine, however the current one compiles OK under 1.0.2.

@OP: try downloading this file:

http://www.gammon.com.au/Arduino/Elapsed.zip

The original one probably didn't have the test for WProgram.h / Arduino.h.
