Overview of this book

Embedded microcontrollers are at the core of many everyday electronic devices. Electronic automotive systems rely on these devices for engine management, anti-lock brakes, in car entertainment, automatic transmission, active suspension, satellite navigation, etc. The so-called internet of things drives the market for such technology, so much so that embedded cores now represent 90% of all processor’s sold. The ARM Cortex-M4 is one of the most powerful microcontrollers on the market and includes a floating point unit (FPU) which enables it to address applications. The ARM Cortex-M4 Microcontroller Cookbook provides a practical introduction to programming an embedded microcontroller architecture. This book attempts to address this through a series of recipes that develop embedded applications targeting the ARM-Cortex M4 device family. The recipes in this book have all been tested using the Keil MCBSTM32F400 board. This board includes a small graphic LCD touchscreen (320x240 pixels) that can be used to create a variety of 2D gaming applications. These motivate a younger audience and are used throughout the book to illustrate particular hardware peripherals and software concepts. C language is used predominantly throughout but one chapter is devoted to recipes involving assembly language. Programs are mostly written using ARM’s free microcontroller development kit (MDK) but for those looking for open source development environments the book also shows how to configure the ARM-GNU toolchain. Some of the recipes described in the book are the basis for laboratories and assignments undertaken by undergraduates.

Introduction


This chapter will introduce you to writing programs in C, a high-level language developed in the 1970s and popular amongst embedded system developers. It is not the only high-level language that can be used to target embedded system applications, but it is the most widely used, because it produces executable code that is compact and very efficiently executed. Standards for C are published by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO). The current standard for the C Programming Language (C11) is ISO/IEC 9899:2011 (http://www.open-std.org/jtc1/sc22/wg14/www/standards).

Becoming a competent C programmer will take time, and although this chapter provides a starting point, you will undoubtedly need to consult other texts that provide a more thorough treatment of the topic. There are also a number of online resources such as http://crasseux.com/books/ctutorial/ and http://www.csd.uwo.ca/~jamie/C/index.html.
