ARM® Cortex® M4 Cookbook

Over 30 hands-on recipes that will help you develop amazing real-time applications using GPIO, RS232, ADC, DAC, timers, audio codecs, graphics LCD, and a touch screen

About This Book

• This book focuses on programming embedded systems using a practical approach
• Manipulate digital audio samples to create digital filters and other amazing audio effects
• The recipes in this book are written using ARM's uVision5 integrated development environment, which is the most comprehensive software development solution available

Who This Book Is For

This book is aimed at electrical engineers and embedded system engineers who want to get started with development of ARM Cortex applications in a short span. Basic knowledge of programming concepts is essential.

What You Will Learn

• Compile, download, and run simple programs on an evaluation board
• Investigate some of the functions that configure I/O devices
• Perform multimedia projects using the touchscreen and codec
• Use an audio codec's beep generator to play a tune
• Write a multi-threaded program using flags for communication
• Get to know about tools for debugging programs that use the CMSIS-RTOS kernel

In Detail

Embedded microcontrollers are at the core of many everyday electronic devices such as cameras, TVs, washing machines, dishwashers, microwaves, and mobile phones. The so-called Internet of Things drives the market for such technology, so much so that embedded cores now represent 90% of all processors 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 that hitherto have been the domain of more specialized digital signal processing chips.

The book begins with an introduction to the ARM Cortex family and covers the basic concepts. Next we cover the installation of the ARM uVision Integrated Development Environment and topics such as target devices, evaluation boards, code configuration, and GPIO. You will then learn about core programming topics that deal with structures, functions, pointers, and debugging. Moving on, you will find out about advanced aspects such as data conversion, multimedia support, real-time signal processing, and real-time embedded systems. Moving ahead, you will also get accustomed to creating game applications, programming I/O, and configuring GPIO and UART ports. By the end of the book, you will be able to successfully create robust and scalable ARM Cortex based applications.

About This Book

• This book focuses on programming embedded systems using a practical approach
• Examples show how to use bitmapped graphics and manipulate digital audio to produce amazing games and other multimedia applications
• The recipes in this book are written using ARM's MDK Microcontroller Development Kit which is the most comprehensive and accessible development solution

Who This Book Is For

This book is aimed at those with an interest in designing and programming embedded systems. These could include electrical engineers or computer programmers who want to get started with microcontroller applications using the ARM Cortex M4 architecture in a short time frame. This book's recipes can also be used to support students learning embedded programming for the first time. Basic knowledge of programming using a high-level language is essential but those familiar with other high-level languages such as Python or Java should not have too much difficulty picking up the basics of embedded C programming.

What You Will Learn

• Use ARM's uVision MDK to configure the microcontroller run time environment (RTE), create projects and compile, download, and run simple programs on an evaluation board
• Use and extend device family packs to configure I/O peripherals
• Develop multimedia applications using the touchscreen and audio codec beep generator
• Write multi-threaded programs using ARM's real-time operating system (RTOS)
• Write critical sections of code in assembly language and integrate these with functions written in C
• Fix problems using ARM's debugging tool to set breakpoints and examine variables
• Port uVision projects to other open source development environments
