Previously, we’ve looked at the basics of hardware manipulation in C++ and applied that to a simple GPIO implementation.

In this article we’re going to have a look at encapsulating our code in a class and look at some of the design choices we have to make.

If you’re not familiar with hardware manipulation in C++ I’d highly recommend reading the previous articles in this series before continuing.

Even if you’re familiar with the concepts of hardware manipulation, if you haven’t read the […]

Introduction

Last time we looked at template functions, which introduced the concept of generic programming in C++.

This time let’s extend the idea of generic programming to

Virtual functions

Virtual functions in C++ exist to maintain the consistent behaviour of polymorphism when accessing derived objects via base class pointers. (If that statement has made your head spin, I’d suggest reading this article before carrying on)

class Base
{
public:
virtual void v_op();
};

class Derived : public Base
{
public:
virtual void v_op();
}

I can access either a Base object or a Derived object via a Base pointer; and I should get the appropriate behaviour for the actual type of the object I’m pointed at:

Base* […]
