Hi,
I am using the Pololu Arduino Library for their servo controller and I have been able to run some of the given example code and make it work with a servo.
Now I am trying to include this code into a larger piece so I would like to put it in an object for working with the MicroMaestro. I have a header file and an .ino file for this object but when I try to compile these files I get an no matching function for call to ‘MicroMaestro::MicroMaestro()’. Below is my code and the error.
servo_obj.h
#ifndef servo_obj_h
#define servo_obj_h
#include <PololuMaestro.h>
#include <Arduino.h>
// servo class
class servo_obj {
public:
servo_obj();
void set_target(int target, unsigned long interval);
bool is_servo_moving();
private:
MicroMaestro flap_driver;
unsigned long period;
unsigned long time_now;
};
#endif
servo_obj.ino
/*
Before using this example, you should go to the Serial Settings
tab in the Maestro Control Center and apply these settings:
Serial mode: UART, fixed baud rate
Baud rate: 9600
CRC disabled
Be sure to click “Apply Settings” after making any changes.
*/
#include “servo_obj.h”
#include <PololuMaestro.h>
/* On boards with a hardware serial port available for use, use
that port to communicate with the Maestro. For other boards,
create a SoftwareSerial object using pin 2 to receive (RX) and
pin 3 to transmit (TX). */
#ifdef SERIAL_PORT_HARDWARE_OPEN
#define maestroSerial SERIAL_PORT_HARDWARE_OPEN
#else
#include <SoftwareSerial.h>
SoftwareSerial maestroSerial(2, 3);
#endif
/* Next, create a Maestro object using the serial port.
Uncomment one of MicroMaestro or MiniMaestro below depending
on which one you have. */
MicroMaestro maestro(maestroSerial);
//MiniMaestro maestro(maestroSerial);
servo_obj::servo_obj()
{
// Set the serial baud rate.
maestroSerial.begin(9600);
}
void servo_obj::set_target(int target, unsigned long interval)
{
/* setTarget takes the channel number you want to control, and
the target position in units of 1/4 microseconds. A typical
RC hobby servo responds to pulses between 1 ms (4000) and 2
ms (8000). */
// Set the target of channel 0 to 1500 us, and wait 2 seconds.
maestro.setTarget(0, 6000);
delay(2000);
// Set the target of channel 0 to 1750 us, and wait 2 seconds.
maestro.setTarget(0, 7000);
delay(2000);
// Set the target of channel 0 to 1250 us, and wait 2 seconds.
maestro.setTarget(0, 5000);
delay(2000);
}
This is the exact error I am getting
