Available in PDF, EPUB and Kindle. Book excerpt: The Raspberry Pi makes an ideal match for the Internet of Things. To put it to good use in IoT you need two areas of expertise, electronics and programming and this presents a barrier to getting started. However, there is an overlooked route that can provide a shortcut. Pi OS, the Raspberry Pi's operating system is Linux based and Linux drivers are available for many off-the-shelf IoT devices. These provide a very easy-to-use, high-level way of working. The problem that this book solves is that there is very little documentation to help you get started. In it Harry Fairhead explains the principles so that you can tackle new devices and he also guides you through of using external hardware via standard Linux drivers. Throughout this book you will find a practical approach to understanding electronic circuits and datasheets and translating this to code, specifically using the C programming language. The main reason for choosing C is speed, a crucial factor when you are writing programs to communicate with the outside world and if you are familiar with another programming language, C shouldn't be hard to pick up. After a quick tour of the Raspberry Pi ecosystem, Visual Studio Code (VS Code) and how it can be used to develop remotely, is introduced. The first IoT program anyone writes is "blinky" to flash an LED and this book is no exception, but it might not be quite what you expect. Instead of using a GPIO line it uses the Linux LED driver - no hardware and no fuss. The GPIO isn't left out, however, as the next three chapters focus on its use via the new GPIO character driver, which replaces the old and very common sysfs GPIO driver. This is the way to do modern GPIO. A key component in any look at Linux and its relationship to hardware is the relatively new Device Tree. While most accounts of this resource are aimed at device driver writers, this one is aimed at device driver users and to this end we look at the DHT22 temperature and humidity driver. After a brief detour into some basic electronics, we look at Pulse Width Modulation supported via a driver rather than needing to be implemented using the GPIO. From here we tackle the two standard buses, I2C and SPI, first going through the basics and then looking at the two attempts to impose a higher organization, the hardware monitoring system, Hwmon, and Industrial I/O, IIO. The third standard bus, although generally not supported in hardware is the 1-Wire bus. This is covered in detail and even includes an introduction to using Netlink, which uses the sockets API to send messages to and from the kernel to access the driver. The final chapter takes things to the next level and considers creating your own custom overlays by writing fragments to the device tree. Harry Fairhead has worked with microprocessors, and electronics in general, for many years and is an enthusiastic proponent of the IoT. He is the author of Raspberry Pi IoT in C, which has recently been republished in its second edition, updated for Raspberry Pi 4 and co-author of Raspberry Pi IoT in Python Using GPIO Zero. His other recent books include Micro: bit IoT in C, Fundamental C: Getting Closer To The Machine and Applying C For The IoT With Linux.

Throughout this book you will find a practical approach to understanding electronic circuits and datasheets and translating this to code, specifically using the C programming language. This second edition was prompted by the advent of the Pi 5, welcomed as the fastest member of the Raspberry Pi family. What came as a shock is that, from the point of view of IoT, it is incompatible with all other Raspberry Pis due to the use of a custom chip. Luckily, although the Pi 5 cannot work with the standard IoT libraries it does behave in the same way under Linux drivers and so this new book does include the Pi 5 on an equal footing. Coverage also includes the Pi Zero 2W, which has a quad-core chip making it more capable than both the original Pi Zero and the WiFi-enabled Pi ZeroW. After a quick tour of the Raspberry Pi ecosystem, Visual Studio Code (VS Code) and how it can be used to develop remotely, is introduced.

To put it to good use in IoT you need two areas of expertise, electronics and programming, and this presents a barrier to getting started. However, there is an overlooked route that can provide a shortcut. Pi OS, the Raspberry Pi's operating system, is Linux- based and Linux drivers are available for many off-the-shelf IoT devices. Using Linux drivers saves the effort of implementing low-level code and has the advantage of working the same on all versions of the Pi, including the recently launched Pi 5 which isn't hardware compatible with earlier versions. This Second Edition has been updated to cover the Pi 5 and also the Pi Zero 2W, which is an ideal candidate for use in IoT projects. It has also been updated to use the latest versions of Pi OS, Bullseye and Bookworm. Throughout this book you will find a practical approach to understanding electronic circuits and datasheets and translating this to code, specifically using Python and VS Code.

Throughout this book you will find a practical approach to understanding electronic circuits and datasheets and translating this to code, specifically using Python. Python is an excellent language for learning about the IoT or physical computing. It might not be as fast as C, but it is much easier to use for complex data processing. The emphasis in this book is on understanding how things work so that you can apply your new knowledge to your own projects. You can use any Python development system that you know, but the programs in the book have been developed using Visual Studio Code and its remote development facilities. The first IoT program anyone writes is "Blinky" to flash an LED and this book is no exception, but it might not be quite what you expect. Instead of using a GPIO line, it uses the Linux LED driver - no hardware and no fuss. The GPIO isn't left out, however, as the next three chapters focus on its use via the new GPIO character driver, which replaces the old and very common sysfs GPIO driver.

The final chapter takes things to the next level and considers creating your own custom overlays by writing fragments to the device tree. This is the second title jointly authored by Harry Fairhead and Mike James and can be seen as the alternative approach to that outlined in Raspberry Pi IoT In Python Using GPIO Zero. For both books, Harry brings his expertise in electronics and the IoT and Mike contributes the Python code. Harry Fairhead is the author of other IoT-related titles including Raspberry Pi IoT in C, Second Edition; Micro: bit IoT in C, Second Edition; Applying C For The IoT With Linux and Fundamental C: Getting Closer To The Machine.

Available in PDF, EPUB and Kindle. Book excerpt: Reviews of the previous edition: "A complete explanation that makes it straightforward to interface I/O options to the Pi. Good examples are easy to follow and well explained - starting with "Hello World" and then walks through the various interface options available with GPIO. I highly recommend this to anyone using the Pi for any embedded system application requiring various types of interfaces." "This is the book to read to get deep into Raspberry IoT. Programming examples are provided. Great book!" The Raspberry Pi makes an ideal match for the Internet of Things. But to put it to good use in IoT you need two areas of expertise, electronics and programming and, because of the way hardware and software engineering tend to occupy separate niches, you may need help with combining the two which is the role of this book. This 3rd Edition was prompted by the arrival of the Pi 5. Unfortunately, as the Pi 5 uses the new RP1 chip to implement its peripherals, it is incompatible with all of the IoT libraries that work directly with the hardware. As a result it is excluded from much of this book. A whole chapter is, however, devoted to getting started with an IoT project with the Pi 5 and it is also covered in chapters on the Linux GPIO driver and on the use of the Pi's serial ports and in a chapter, which describes how to access the Pi 5's registers directly. What is more important than the Pi 5 from the point of view of IoT is the Pi Zero 2W, which is a much faster, quad-core, version of the Pi Zero W making it an excellent choice for IoT projects. It is covered for the first time in this edition. Another reason for a new edition is to update its programs to the new versions of Pi OS, Bookworm and Bullseye. Finally, a major change is that VS Code is now the book's IDE of choice and to make it easy to use as a remote development environment with all versions of Pi from Pi Zero to Pi 5, a set of custom VS Code tasks are supplied, which are downloadable as well as included in the book. The main idea in this book is to work directly with the hardware using the Raspberry Pi's GPIO (General Purpose Input Output) to connect with off-the-shelf sensors. After reading it you will be in a better position to tackle interfacing anything-with-anything without the need for custom drivers and prebuilt hardware modules. Harry Fairhead has worked with microprocessors and electronics for many years and is an enthusiastic proponent of the IoT. C is his programming language of choice and he has written several books on programming the Raspberry Pi and other devices in an IOT context, including Raspberry Pi IoT in C With Linux Drivers, Second Edition, Programming the ESP32 in MicroPython and Fundamental C: Getting Closer To The Machine. Currently, his most popular title is Programming the Raspberry Pi Pico/W in C.

Book excerpt: The Raspberry Pi makes an ideal match for the Internet of Things. But to put it to good use in IoT you need two areas of expertise, electronics and programming and, because of the way hardware and software engineering tend to occupy separate niches, you may need help with combining the two. This book teaches you to think like an IoT programmer. In Raspberry Pi IoT in C you will find a practical approach to understanding electronic circuits and datasheets and translating this to code, specifically using the C programming language. The main reason for choosing C is speed, a crucial factor when you are writing programs to communicate with the outside world. If you are familiar with another programming language, C shouldn't be hard to pick up. This Second Edition has been brought up-to-date and focuses mainly on the Pi 4 and the Pi Zero. There is new material on the recently introduced GPIO character driver and using the Pi 4's additional ports and scheduling. Although NetBeans is used to develop programs, VS Code is now considered an alternative remote development environment and all the book's code, which is available for download, has been tested with VS Code. The main idea in this book is to not simply install a driver, but to work directly with the hardware using the Raspberry Pi's GPIO (General Purpose Input Output) to connect with off-the-shelf sensors. It explains how to use its standard output with custom protocols, including an in-depth exposition of the 1-wire bus. You will also discover how to put the Internet into the IoT using sockets. After reading this book you will be in a better position to tackle interfacing anything-with-anything without the need for custom drivers and prebuilt hardware modules.

Available in PDF, EPUB and Kindle. Book excerpt: The Raspberry Pi makes an ideal match for the Internet of Things. But to put it to good use in IoT you need two areas of expertise, electronics and programming and because of the way hardware and software engineering tend to occupy separate niches, you may need help with combining the two which is what this book sets out to do. Python is an excellent language for learning about physical computing. It might not be as fast as C, but it is much easier to use for complex data processing. One reason for Python's popularity is its wealth of supporting libraries and there are several for interfacing hardware. The GPIO Zero library is the official way to use Python with the GPIO and other devices and this book looks at how to use it to interface to fundamental IoT devices - from LEDs and buzzers to servos and stepper motors and several off-the-shelf Raspberry Pi add-ons. This revised second edition had been expanded to cover all the current Raspberry Pis including the latest, the Pi 5, and the Pi Zero 2W which, with its WiFi capability and being a quad-core device, is an ideal device for IoT projects. It has also been updated to cover the latest version of the GPIO Zero library, which is both the library recommended by Raspberry Pi and the only one that works with the Pi 5. The emphasis in this book is about using and understanding the hardware and GPIO Zero. It not only shows you how to "follow the beaten track", but how to create your own tracks. While it isn't a project book, many of the code examples described are part way to projects and all of the devices and techniques described can be used to create practical projects. Similarly while it doesn't teach you the whole of Python, it does bring you up to speed in the aspects of the language needed for interfacing with hardware. Harry Fairhead has worked with microprocessors, and electronics in general, for many years and is an enthusiastic proponent of the IoT. He is the author of Raspberry Pi IoT in C, which has recently been republished in its third edition, and Raspberry Pi IoT in C Using Linux Drivers, now in its second edition. Mike James is the co-author Raspberry Pi IoT in Python Using Linux Drivers, Second Edition. He is also the author of the Programmer's Python: Something Completely Different series of books.

Available in PDF, EPUB and Kindle. Book excerpt: C is a good language to learn. It was designed to do a very different job from most modern languages and the key to understanding it is not to just understand the code, but how this relates to the hardware. Fundamental C takes an approach that is close to the hardware, introducing addresses, pointers, and how things are represented using binary. An important idea is that everything is a bit pattern and what it means can change. As a C developer you need to think about the way data is represented, and Harry Fairhead encourages this. He emphasizes the idea of modifying how a bit pattern is treated using type punning and unions. This power brings with it the scourge of the C world - undefined behavior - which is ignored in many books on C. Here, not only is it acknowledged, it is explained together with ways to avoid it. A particular feature of the book is the way C code is illustrated by the assembly language it generates. This helps you understand why C is the way it is. For beginners, the book covers installing an IDE and GCC before writing a Hello World program and then presents the fundamental building blocks of any program - variables, assignment and expressions, flow of control using conditionals and loops. Once the essentials are in place, data types are explored before looking at arithmetic and representation. Harry then goes deeper into evaluating expressions before looking at functions and their scope and lifetime. Arrays, strings, pointers and structs are covered in separate chapters, as is bit manipulation, a topic that is key to using C, and the idea of a file as the universal approach to I/O. Finally, he looks at the four stages of compilation of a C program, the use of static and dynamic libraries and make. This is C as it was always intended to be written - close to the metal. Harry Fairhead has a hardware background and, having worked with microprocessors and electronics in general, for many years, he is an enthusiastic proponent of the IoT. His recent titles include Raspberry Pi IoT in C and Micro: bit IoT in C. His next, Applying C For The IoT With Linux at intermediate/advanced level is intended as a companion to this book for those working in a Linux/POSIX environment, in particular the Raspberry Pi.

The extra capabilities added to the Pico W open up loads of opportunities, but only if you are prepared to do battle with the two libraries that provide networking and security - lwIP and mbedtls respectively. The problem with these large libraries of code is that they are poorly documented and don't refer directly to the Pico W and its SDK. This book sets out to remedy this by providing a guide to these libraries along with examples of what you can do with them. Having introduced the Pico WiFi Stack and basic network connections, we look at how to use TCP to create the all-important Protocol Control Block and then tackle implementing an HTTP client. As well as covering the basic mechanics of using lwIP, we also concentrate on how to organize the use of an asynchronous library based on callbacks. The problem of IoT security is unique because IoT devices can be physically accessed by an attacker and hence any secrets embedded in their code have to be considered almost as public knowledge. Even so it is worth implementing encryption and this is achieved using mbedtls to create an HTTPS client. If you can ensure the physical security of the IoT device, then running it as a server is possible and this is covered in both HTTP and HTTPS modes, complete with certificates. We cover the basics of cryptography, including the problem of generating random numbers, what an encryption suite is and the various modes of AES encryption. The later chapters are devoted to specific protocols, making use of both lwIP and mbedtls. We look at UDP; SNTP to set the Pico W's real time clock; SMTP to allow email notifications and MQTT. Harry Fairhead is also the author of Programming The Raspberry Pi Pico/W In C; Raspberry Pi IoT in C, Raspberry Pi IoT In C Using Linux Drivers, Applying C For The IoT With Linux, Fundamental C: Getting Closer To The Machine and Micro: bit IoT in C. Mike James is the author of Programming the Raspberry Pi Pico/W in MicroPython; Raspberry Pi IoT In Python Using GPIO Zero; and the Programmer's Python: Something Completely Different series of books and several other programming and computer science titles in the I Programmer Library.

Available in PDF, EPUB and Kindle. Book excerpt: The Raspberry Pi Pico is a remarkable microcontroller. It has a power and sophistication that would have been unthinkable just a short time ago. For the sort of jobs it is ideal for, it has plenty of processing power and enough memory to make tasks that would have once required careful planning, relatively easy. Instead of struggling with the machine, you can now focus on getting a good implementation of your algorithms. To enjoy all of its power and sophistication there is no better language than C. It wastes none of the power and it gives you what you need to get at the new features. However, getting started with the Pico with C is no easy feat, which is what motivated this book about creating programs so that testing and debugging is easy. Programming the Raspberry Pi Pico in C uses the highly popular VS Code as its development environment and shows how to use a Raspberry Pi or a desktop PC running Windows as your development machine. The purpose of the book is to reveal what you can do with the Pico's GPIO lines together with widely used sensors, servos and motors and ADCs. After covering the GPIO, outputs and inputs, events and interrupts, it gives you hands-on experience of PWM (Pulse Width Modulation), the SPI bus, the I2C bus and the 1-Wire bus. One of the key advantages of the Pico is its PIO (Programmable I/O) and while this is an advanced feature it is included in this book. After finding out how the PIO works, we apply it to writing a PIO program for the DHT22 and the 1-Wire bus. One current drawback of the Pico it is that it doesn't have a network connection. To solve this problem there is a chapter on using the low-cost ESP8266 as a WiFi client and web server. The two devices together make the Pico a true IoT device. Harry Fairhead has a hardware background and, having worked with microprocessors and electronics in general, for many years, he is an enthusiastic proponent of the IoT and embedded computing. He is the author of two books intended for C programmers, Fundamental C: Getting Closer To The Machine and Applying C For the IoT With Linux and four books on the using the Raspberry Pi in an IoT context, two using C and two using Python. He is now working on a Python version of this book for the Pico.
