servotimer2 problems

Using Arduino IDE 1.x
1

I installed within the libraries in a folder called ServoTimer2 the 3 files that make up the zip.
When I try to compile this simple code:

#include <ServoTimer2.h>
void setup(){}
void loop(){}

I get the following error.
/home/marcelo/arduino-1.0.3/libraries/ServoTimer2/ServoTimer2.cpp:5:26: error: WConstants.h: No existe el archivo o el directorio
/home/marcelo/arduino-1.0.3/libraries/ServoTimer2/ServoTimer2.cpp: In function ‘void __vector_9()’:

/home/marcelo/arduino-1.0.3/libraries/ServoTimer2/ServoTimer2.cpp:65: error: ‘pinMode’ was not declared in this scope

Thank you very much to who can guide me in the solution.

PS: Use this library to use the module VirtualWire, if they know of any better combination even better.

 WConstants.h

Substitute "Arduino.h"

I have the same problem with servotimer2 when i change Wconstant to Arduino.h I had this errors

Hi I just fix the error you have to change in servoTimer2.ccp this:

extern "C" {
  // AVR LibC Includes
#include <inttypes.h
#include <avr/interrupt.h>
 #include <WConstants.h>
}

For this:

#include<Arduino.h>

If you don´t change all you will have more errors

Hi I just fix the error you have to change in servoTimer2.ccp this:
Code: [Select]
extern "C" {
// AVR LibC Includes
#include <inttypes.h
#include <avr/interrupt.h>
#include <WConstants.h>
}

For this:
Code: [Select]
#include<Arduino.h>

I have done it but still I get all these errors:

C:\Program Files (x86)\Arduino\libraries\ServoTimer2\ServoTimer2 - Copia.cpp:6:26: error: WConstants.h: No such file or directory

Can anyone help?

This is what ServoTimer2.cpp looks like now:

/* ServoTimer2.cpp*/
extern "C" {
  // AVR LibC Includes
  #include <Arduino.h>
  
}
#include <wiring.h>
#include "ServoTimer2.h"
static void initISR();
static void writeChan(uint8_t chan, int pulsewidth);
...

Solved :slight_smile:
I had to change the code from this:

/* ServoTimer2.cpp*/
extern "C" {
  // AVR LibC Includes
  #include <inttypes.h>
  #include <avr/interrupt.h>
  #include "WConstants.h"
}
#include <wiring.h>
#include "ServoTimer2.h
...

to this:

/* ServoTimer2.cpp*/

#include <Arduino.h>
 
#include <wiring.h>
#include "ServoTimer2.h"
...

Simple but not obvious to me :wink:
