Raspberry Pi for Secret Agents

Raspberry Pi for Secret Agents

Stefan Sjogelid

Packt Publishing Limited
2013
nidottu
A playful, informal approach to using the Raspberry Pi for mischief! Raspberry Pi for Secret Agents is for all mischievous Raspberry Pi owners who'd like to see their computer transform into a neat spy gadget to be used in a series of practical pranks and projects. No previous skills are required to follow along and if you're completely new to Linux, you'll pick up much of the basics for free. Apart from the Raspberry Pi board itself, a USB microphone and/or a webcam is required for most of the audio/video topics and a Wi-Fi dongle is recommended for the networking examples. A Windows/Mac OS X/Linux computer (or second Raspberry Pi) is also recommended for remote network access.

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. Here it is used in conjunction with NetBeans and with the bcm2835 library.The main idea in this book is to not simply install a driver, but to work directly with the hardware. So rather than using Raspberry Pi HATs or other expansion boards we use the Pi's GPIO (General Purpose Input Output) and connect off-the-shelf sensors. If you want to know how to work with the GPIO lines directly, how to work with near realtime Linux and generally take control of the Pi this is the book you need. It explains how to use the standard bus types - SPI, I2C, PWM - and 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 and the low cost ESP8266.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.Having written a Blinky program to check that everything we need is installed and working we move on to exploring the basics of using the GPIO and also master memory mapping, pulse width modulation and other more sophisticated bus types. From here we can start connecting sensors, which is a core requirement for IoT. First we'll meet the ubiquitous I2C bus, next we'll implement a custom protocol for a one-wire bus, and eventually we'll add eight channels of 12-bit AtoD with the SPI bus, which involves overcoming some subtle difficulties. Next we look at the traditional serial interface how to use it to communicate with other devices. This paves the way for getting the Pi on the web - after all this is a book about the Internet of Things -using first a USB WiFi adapter and sockets and then the low cost ESP8266, which is particularly useful with the Pi Zero which has only one USB port. Having transformed the Pi into both a web client and a web server we can then use them to exchange information.

There is a new edition of this book.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.

There is a new edition of this book covering GPIO Zero 2 and the Pi 5 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. Python is an excellent language with which to learn 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. 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. Importantly, it explains how it works so that you can extend it to custom devices. Studying GPIO Zero is also a great way to improve your Python and this book teaches you to think like an IoT programmer. 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.The emphasis in this book on understanding how things work and using this knowledge to create new devices and integrate them into GPIO Zero.

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.

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.

'I went to the shops and bought...' has been a popular listening game for families for hundreds of years. Besides teaching children the rules for taking turns, this traditional past-time helps with memory and can be an invaluable aid to socialization. It is certainly one of my family's favorite go-to activities on long car trips and before bedtime, and I can testify that it brings our family closer together.So, it was little wonder that when the time came to create the first ever Baba Malay Reader that I fell back on an old and trusty treasure.Gua Pi Keday or I went to the Shops, is now being used to teach the Peranakan vocabulary (kata-kata) and to introduce beginners to the 22 letters that compose the Baba Malay alphabet. Fun, educational and challenging: a new tool in the introduction of our beloved Baba Malay language.The first book in the series New Peranakan Tales created to complement the Baba Malay Today series.
