The Vidstrom Labs Guide To Advanced Arduino Internals For The Uno And Mega 2560

Prerequisites _are_ required for this in-depth tour through the intriguing worlds of the Arduino Uno and Mega 2560. Few details are too insignificant to remain unexplored here. Coverage includes the internals of: digital I/O, the I2C bus, the SPI bus, the Hardware Serial Library, STK500, STK500v2, interrupts, the boot sequence from power-on to setup() and loop(), analogWrite(), analogRead(), time and delays, the EEPROM Library, PROGMEM, and F().

This isn't a book for the faint of heart. The Arduino Due is quite a different beast compared to the more common Arduino Uno. It uses the Arm Cortex-M3 microcontroller SAM3X8E from Microchip (formerly Atmel). Learning the internals of the Due is a possible bridge from the more straightforward world of the Arduino into the much more complicated world of Arm. If you've come this far, I assume that you have ambitions way beyond using only the Arduino API. This is a journey into the world of Arm. Coverage includes the internals of: Uploading over the programming port and the native port The boot sequence from power-on to setup() and loop() The clock tree Digital I/O, including glitch filtering and debouncing Interrupts, including SysTick and the NVIC Flashing and debugging via JTAG Bare metal development for the Due with the GNU Arm Embedded Toolchain and makefiles Time and delays The Serial object analogWrite() analogRead() The USB stack including the UDD, the USB Core, PluggableUSB, PluggableUSBModule, the HID Library, the Mouse Library, and the Keyboard Library The SPI Library The Wire Library (I2C)

Do you already know how to program the Arduino in C/C++ and want to delve deeper? This book guides you step by step from being an absolute beginner to knowing how to use assembly language in your Arduino sketches. We work inside the familiar Arduino IDE, and you can download all the source code from the companion website. All you need is an Arduino Uno or an Arduino Mega 2560, without any extra hardware or electronic components. Both are based upon 8-bit AVR RISC microcontrollers, and you will learn how to use AVR assembly for jumping, branching, logic operations, bit shifting and rotating, arithmetic, I/O, and more. You will also learn about the stack, function calling conventions, and interrupts.

Arduino Internals guides you to the heart of the Arduino board. Author Dale Wheat shares his intimate knowledge of the Arduino board—its secrets, its strengths and possible alternatives to its constituent parts are laid open to scrutiny in this book. You'll learn to build new, improved Arduino boards and peripherals, while conforming to the Arduino reference design. Arduino Internals begins by reviewing the current Arduino hardware and software landscape. In particular, it offers a clear analysis of how the ATmega8 board works and when and where to use its derivatives. The chapter on the "hardware heart" is vital for the rest of the book and should be studied in some detail. Furthermore, Arduino Internals offers important information about the CPU running the Arduino board, the memory contained within it and the peripherals mounted on it. To be able to write software that runs optimally on what is a fairly small embedded board, one must understand how the different parts interact. Later in the book, you'll learn how to replace certain parts with more powerful alternatives and how to design Arduino peripherals and shields. Since Arduino Internals addresses both sides of the Arduino hardware-software boundary, the author analyzes the compiler toolchain and again provides suggestions on how to replace it with something more suitable for your own purposes. You'll also learn about how libraries enable you to change the way Arduino and software interact, and how to write your own library implementing algorithms you've devised yourself. Arduino Internals also suggests alternative programming environments, since many Arduino hackers have a background language other than C or Java. Of course, it is possible to optimize the way in which hardware and software interact—an entire chapter is dedicated to this field. Arduino Internals doesn't just focus on the different parts of Arduino architecture, but also on the ways in which example projects can take advantage of the new and improved Arduino board. Wheat employs example projects to exemplify the hacks and algorithms taught throughout the book. Arduino projects straddling the hardware-software boundary often require collaboration between people of different talents and skills which cannot be taken for granted. For this reason, Arduino Internals contains a whole chapter dedicated to collaboration and open source cooperation to make those tools and skills explicit. One of the crowning achievements of an Arduino hacker is to design a shield or peripheral residing on the Arduino board, which is the focus of the following chapter. A later chapter takes specialization further by examining Arduino protocols and communications, a field immediately relevant to shields and the communication between peripherals and the board. Finally, Arduino Internals integrates different skills and design techniques by presenting several projects that challenge you to put your newly-acquired skills to the test! Please note: the print version of this title is black & white; the eBook is full color.

This book is about the Arduino microcontroller and the Arduino concept. The visionary Arduino team of Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, and David Mellis launched a new innovation in microcontroller hardware in 2005, the concept of open-source hardware. Their approach was to openly share details of microcontroller-based hardware design platforms to stimulate the sharing of ideas and promote innovation. This concept has been popular in the software world for many years. In June 2019, Joel Claypool and I met to plan the fourth edition of Arduino Microcontroller Processing for Everyone! Our goal has been to provide an accessible book on the rapidly changing world of Arduino for a wide variety of audiences including students of the fine arts, middle and senior high school students, engineering design students, and practicing scientists and engineers. To make the book more accessible to better serve our readers, we decided to change our approach and provide a series of smaller volumes. Each volume is written to a specific audience. This book, Arduino I: Getting Started is written for those looking for a quick tutorial on the Arduino environment, platforms, interface techniques, and applications. Arduino II will explore advanced techniques, applications, and systems design. Arduino III will explore Arduino applications in the Internet of Things (IoT). Arduino I: Getting Started covers three different Arduino products: the Arduino UNO R3 equipped with the Microchip ATmega328, the Arduino Mega 2560 equipped with the Microchip ATmega2560, and the wearable Arduino LilyPad.

Modern Assembly Language Programming with the ARM Processor, Second Edition is a tutorial-based book on assembly language programming using the ARM processor. It presents the concepts of assembly language programming in different ways, slowly building from simple examples towards complex programming on bare-metal embedded systems. The ARM processor was chosen as it has fewer instructions and irregular addressing rules to learn than most other architectures, allowing more time to spend on teaching assembly language programming concepts and good programming practice. Careful consideration is given to topics that students struggle to grasp, such as registers vs. memory and the relationship between pointers and addresses, recursion, and non-integral binary mathematics. A whole chapter is dedicated to structured programming principles. Concepts are illustrated and reinforced with many tested and debugged assembly and C source listings. The book also covers advanced topics such as fixed- and floating-point mathematics, optimization, and the ARM VFP and NEONTM extensions. Includes concepts that are illustrated and reinforced with a large number of tested and debugged assembly and C source listing Intended for use on very low-cost platforms, such as the Raspberry Pi or pcDuino, but with the support of a full Linux operating system and development tools Includes discussions of advanced topics, such as fixed and floating point mathematics, optimization, and the ARM VFP and NEON extensions Explores ethical issues involving safety-critical applications Features updated content, including a new chapter on the Thumb instruction set
