Code would not update variable inside drive method. The variable is updated inside the drive method, but it doesn't change in the rest of the class. I wrote a simple similar method in normal C++ and the variable actually updated in the rest of the class.
engine.hpp
#pragma once
#include <Arduino.h>
namespace engine
{
class Engine
{
public:
Engine(const unsigned char t_motor, const unsigned char t_forward, const unsigned char t_backward);
void drive(unsigned int t_speed, bool t_isForward = true);
bool isMovingForward() const;
void stop();
private:
const unsigned char m_motor;
const unsigned char m_forward;
const unsigned char m_backward;
// Movements
bool m_isActive;
bool m_isForward;
unsigned int m_speed;
};
} // namespace engine
engine.cpp init list
Engine::Engine(const unsigned char t_motor, const unsigned char t_forward, const unsigned char t_backward)
: m_motor(t_motor),
m_forward(t_forward),
m_backward(t_backward),
m_isActive(false),
m_isForward(true),
m_speed(0U)
{
}
drive method
void Engine::drive(unsigned int t_speed, bool t_isForward)
{
if (!m_isActive || m_isForward != t_isForward)
{
stop();
// Set direction
if (t_isForward)
{
digitalWrite(m_forward, HIGH);
digitalWrite(m_backward, LOW);
}
else
{
digitalWrite(m_forward, LOW);
digitalWrite(m_backward, HIGH);
}
m_isActive = true;
m_isForward = t_isForward;
}
if (m_speed != t_speed)
{
m_speed = t_speed; // Updated here
analogWrite(m_motor, t_speed);
}
}
