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.

Microcontrollers, like the RP2040 at the heart of Raspberry Pi Pico, are computers stripped back to their bare essentials. You don't use monitors or keyboards with them, but program them over USB to take their input from (and send their output to) their input/output (IO) pins. Using these programmable connections, you can light lights, make noises, send text to screens, and much more. In Get Started with MicroPython on Raspberry Pi Pico, you will learn how to use the beginner-friendly language MicroPython to write programs and connect up hardware to make your Raspberry Pi Pico interact with the world around it. Using these skills, you can create your own electro-mechanical projects, whether for fun or to make your life easier. This book shows you how to: Get started with Raspberry Pi Pico Work with various electronic components Create your own programmable electronic contraptions Work with Programming Input and Output (PIO) for low level, timing-critical projects Learn the Raspberry Pi Pico pinouts for hooking up components Use the I2C and SPI protocols to connect to components By the end of the book, you'll know how to create your own programmable electronic contraptions. What you do with them is up to you.

Learn to program the Raspberry Pi Pico’s dual ARM Cortex M0+ CPUs in Assembly Language. The Pico contains a customer System on a Chip (SoC) called the RP2040, making it the Foundation’s first entry into the low-cost microcontroller market. The RP2040 contains a wealth of coprocessors for performing arithmetic as well as performing specialized I/O functionality. This book will show you how these CPUs work from a low level, easy-to-learn perspective. There are eight new Programmable I/O (PIO) coprocessors that have their own specialized Assembly Language supporting a wide variety of interface protocols. You'll explore these protocols and write programs or functions in Assembly Language and interface to all the various bundled hardware interfaces. Then go beyond working on your own board and projects to contribute to the official RP2040 SDK. Finally, you'll take your DIY hardware projects to the next level of performance and functionality with more advanced programming skills. What You'll Learn Read and understand the Assembly Language code that is part of the Pico’s SDK Integrate Assembly Language and C code together into one program Interface to available options for DIY electronics and IoT projects Who This Book Is For Makers who have already worked with microcontrollers, such as the Arduino or Pico, programming in C or Python. Those interested in going deeper and learning how these devices work at a lower level, by learning Assembly Language.

Expand Raspberry Pi capabilities with fundamental engineering principles Exploring Raspberry Pi is the innovators guide to bringing Raspberry Pi to life. This book favors engineering principles over a 'recipe' approach to give you the skills you need to design and build your own projects. You'll understand the fundamental principles in a way that transfers to any type of electronics, electronic modules, or external peripherals, using a "learning by doing" approach that caters to both beginners and experts. The book begins with basic Linux and programming skills, and helps you stock your inventory with common parts and supplies. Next, you'll learn how to make parts work together to achieve the goals of your project, no matter what type of components you use. The companion website provides a full repository that structures all of the code and scripts, along with links to video tutorials and supplementary content that takes you deeper into your project. The Raspberry Pi's most famous feature is its adaptability. It can be used for thousands of electronic applications, and using the Linux OS expands the functionality even more. This book helps you get the most from your Raspberry Pi, but it also gives you the fundamental engineering skills you need to incorporate any electronics into any project. Develop the Linux and programming skills you need to build basic applications Build your inventory of parts so you can always "make it work" Understand interfacing, controlling, and communicating with almost any component Explore advanced applications with video, audio, real-world interactions, and more Be free to adapt and create with Exploring Raspberry Pi.

This book will teach you Python programming and some basic electronics without assuming any prior knowledge of either subject. The book initially focusses on Python programming, building up a Morse Code example using the Raspberry Pi Pico's built-in LED. Once you have mastered the basics of coding the Pico, the book will introduce electronics, showing you how to use sensors, switches, LEDs, servomotors and displays attached to your Pico. All the parts used in the book are available in a companion kit by MonkMakes Ltd. available from suppliers world-wide. Discover how to: install and use the Thonny Python editor and upload programs to your Pico write simple programs to control the Raspberry Pi Pico structure your programs with functions and modules make effective use of Python Lists and Dictionaries attach sensors, LEDs, servomotors and displays to your Pico and, to program them. make use of the Pico's advanced input/output capabilities
