Hi,
I am trying to write a simple class to handle signal being sent to the Electronic Speed Controllers in my quadcopter using the Servo Library. The Class is not really necessary, but I just want to have it more organize and object oriented. So here’s my code:
header:
#ifndef Motor_h
#define Motor_h
#include <Arduino.h>
#include <Servo.h>
class Motor
{
private:
const int motorNum = 4;
extern Servo motor[4];
public:
Motor( int _pin0, int _pin1, int _pin2, int _pin3);
void writeChannel(int _pin, int _pwm);
void writeAll(int _pwm);
void writePWM(int* _pwm);
};
#endif
And here’s the cpp file:
#include <Arduino.h>
#include <Servo.h>
#include "Motor.h"
Motor::Motor( int _pin0, int _pin1, int _pin2, int _pin3)
{
motor[0].attach(_pin0);
motor[1].attach(_pin1);
motor[2].attach(_pin2);
motor[3].attach(_pin3);
}
void Motor::writeChannel(int _channel, int _pwm)
{
motor[_channel].writeMicroseconds(_pwm);
}
void Motor::writeAll(int _pwm)
{
for (int i = 0; i < motorNum; i++)
writeChannel(i, _pwm);
}
void Motor::writePWM(int* _pwm)
{
for (int i = 0; i < motorNum; i++)
writeChannel(i, _pwm[i]);
}
And here’s the main test code:
#include "Motor.h"
Motor motor(47,49,51,53);
void setup() {
Serial.begin(115200);
delay(3000);
Serial.println("ARM!");
motor.writeAll(1000);
delay(1000);
}
void loop() {
for (int i = 1000; i < 1350; i += 1)
{
Serial.println(i);
motor.writeAll(i);
delay(100);
}
delay(2000);
}
So, I am getting an error while trying to compile:
Motor.cpp:2:19: fatal error: Servo.h: No such file or directory
#include <Servo.h>
^
compilation terminated.
Error compiling.
I am using an Arduino DUE, I tested it before, the Servo library is there. I was able to run the motors. It’s just that when I put this in a class, it seems to be missing? How do I fix this?
Thanks
