ARM® Cortex® M4 Cookbook

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.

The release of uVision5 heralded the integration of software packs to support a range of microcontroller devices and simplify the task of programming I/O by allowing the user to select from a menu of I/O options to provide the necessary source code in our project. This is extremely helpful and represents a huge leap forwards as compared to previous versions of the IDE that provided the user with comparatively little help with configuring I/O libraries. But, it does raise a dilemma; what do we do if our target hardware isn't supported? In this chapter, we'll investigate some of the functions that configure I/O devices and gain an understanding of what is involved in writing I/O interfaces for other targets. We'll need to refer to STM Reference manual RM0090 ( throughout this chapter as it provides complete information on how to use the STM32F405xx/07xx, STM32F415xx/17xx, STM32F42xxx, and STM32F43xxx microcontroller memory and peripherals. We start by writing a program...
