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.

What this book covers

Chapter 1, A Practical Introduction to ARM® Cortex®, shows you how to compile, download, and run simple programs on an evaluation board.

Chapter 2, C Language Programming, introduces you to writing programs in C, a high-level language that was developed in the 1970s and is popular among embedded-system developers.

Chapter 3, Programming I/O, investigates some of the functions that configure I/O devices, and you will gain an understanding of what is involved in writing I/O interfaces for other targets.

Chapter 4, Assembly Language Programming, explains how to write functions in assembly language. Assembly language is a low-level programming language that is specific to particular computer architecture. Therefore, unlike programs written high-level languages, programs written in assembly language cannot be easily ported to other hardware architectures.

Chapter 5, Data Conversion, introduces approaches to data conversion, namely analog to digital conversion and vice versa. This chapter also covers the principal features used by microcontrollers for data conversion.

Chapter 6, Multimedia Support, discusses support for various multimedia peripherals, which are discrete components connected to the microcontroller by a bus. Support for an LCD touchscreen, audio codec, and camera peripherals is a very attractive feature of the STM32F4xxx microcontroller, and selecting an evaluation board that includes these peripherals, although more expensive, will be covered in this chapter.

Chapter 7, Real-Time Signal Processing, introduces you to Digital Signal Processing (DSP) and reviews the ARM Cortex M4 instruction set support for DSP applications. This chapter will walk through a DMA application using the codec, followed by designing a low-pass filter.

Chapter 8, Real-Time Embedded Systems, shows you how to write a multithreaded program using flags for communication and ensuring mutual exclusion when accessing shared resources.

Chapter 9, Embedded Toolchain, teaches you how to install the GNU ARM Eclipse toolchain for the Windows Operating System and to build and run a simple Blinky program on the MCBSTM32F400 evaluation board. This chapter will also show you how to use the STM32CubeMX Framework (API) and how to port projects to GNU ARM Eclipse.
