Raspberry Pi Computer Architecture Essentials

Overview of this book

With the release of the Raspberry Pi 2, a new series of the popular compact computer is available for you to build cheap, exciting projects and learn about programming. In this book, we explore Raspberry Pi 2’s hardware through a number of projects in a variety of programming languages. We will start by exploring the various hardware components in detail, which will provide a base for the programming projects and guide you through setting up the tools for Assembler, C/C++, and Python. We will then learn how to write multi-threaded applications and Raspberry Pi 2’s multi-core processor. Moving on, you’ll get hands on by expanding the storage options of the Raspberry Pi beyond the SD card and interacting with the graphics hardware. Furthermore, you will be introduced to the basics of sound programming while expanding upon your knowledge of Python to build a web server. Finally, you will learn to interact with the third-party microcontrollers. From writing your first Assembly Language application to programming graphics, this title guides you through the essentials.

A C++ equivalent


The following C++ code demonstrates how we can implement the threading program. It shows that there are some subtle differences between C and C++ with regard to outputting strings to the screen. However, as you will discover, C functionality can also be implemented in C++.

It also importantly introduces us to thread termination via the pthread_exit function.

As you will encounter C and C++ used heavily in many hardware projects designed for the Raspberry Pi, this program will give you a basic introduction to C++, which you can use as a jumping off point.

You can read more about C++ at http://www.cplusplus.com/doc/ and find a wealth of tutorials.

Our next task is going to be to create a new file under your c_programs directory:

vim first_cpp_prog.cpp

Let's start by adding the include statements to the top of the file:

#include <iostream>
#include <cstdlib>
#include <pthread.h>

Here we include a library to handle input and output, called iostream. This provides...
