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.

Dr. Mark Fisher

Dr. Mark Fisher is a chartered engineer, MIET. He started his career as an electronics apprentice with the UK Ministry of Defence. This was before he studied Electrical and Electronic Engineering at Aston University, Birmingham. After his graduation, he joined Ferranti Computer Systems, Manchester. However, he returned to academia to study Microprocessor Engineering and Digital Electronics at Manchester University (UMIST), and he then remained as a research assistant within the Department of Computation to gain a PhD in Applied Machine Learning. Currently, he is a senior lecturer at the School of Computing Sciences, University of East Anglia, and the course director of the Computer Systems Engineering Degree programme. Many of the recipes in this book were originally developed in the context of a taught module that Mark leads, which is popular among undergraduate and master's students in the school. Mark currently researches in the fields of medical imaging and computer vision, and he is a co-author of over a hundred journal and conference papers in this area.
