Practical Multitasking Fundamentals Programming embedded systems is difficult because of resource constraints and limited debugging facilities. Why develop your own Real-Time Operating System (RTOS) as well as your application when the proven FreeRTOS software is freely available? Why not start with a validated foundation? Every software developer knows that you must divide a difficult problem into smaller ones to conquer it. Using separate preemptive tasks and FreeRTOS communication mechanisms, a clean separation of functions is achieved within the entire application. This results in safe and maintainable designs. Practicing engineers and students alike can use this book and the ESP32 Arduino environment to wade into FreeRTOS concepts at a comfortable pace. The well-organized text enables you to master each concept before starting the next chapter. Practical breadboard experiments and schematics are included to bring the lessons home. Experience is the best teacher. Each chapter includes exercises to test your knowledge. The coverage of the FreeRTOS Application Programming Interface (API) is complete for the ESP32 Arduino environment. You can apply what you learn to other FreeRTOS environments, including Espressif’s ESP-IDF. The source code is available from GitHub. All of these resources put you in the driver’s seat when it is time to develop your next uber-cool ESP32 project. What you will learn: How preemptive scheduling works within FreeRTOS The Arduino startup “loopTask” Message queues FreeRTOS timers and the IDLE task The semaphore, mutex, and their differences The mailbox and its application Real-time task priorities and its effect Interrupt interaction and use with FreeRTOS Queue sets Notifying tasks with events Event groups Critical sections Task local storage The gatekeeper task

Affordable development boards, powerful software tools, and readily available documentation make it possible to turn an idea into a working prototype in very little time. MicroPython plays an important role in this development by offering a readable, interactive way to control microcontrollers while still providing direct access to their hardware features. This book explores embedded programming with MicroPython using an STM32-based Nucleo board. It shows how a microcontroller continuously interacts with its environment by reading inputs, processing information, and controlling outputs. Step by step, you will learn to flash LEDs, measure analog signals, work with sensors, control actuators, and exchange data with other devices. The built-in REPL makes it easy to test instructions immediately, inspect results, and learn through experimentation. Although microcontroller boards differ in size, speed, memory, and peripherals, the fundamental concepts remain largely the same. Digital input and output, analog conversion, timers, PWM, interrupts, and serial communication are the essential building blocks of embedded applications. By concentrating on these transferable principles, the book provides a foundation that remains useful when moving to other boards, processors, or development environments. It is intended both for newcomers and for programmers who want to expand into embedded systems. MicroPython offers a practical route into this field, combining quick results with a clear understanding of how software and hardware work together.

Understanding and Using Them Effectively What happens in electronics is invisible to the naked eye. The instrument that allows to accurately visualize electrical signals, the one through which the effects of electronics become apparent to us, is the oscilloscope. Alas, when one first ventures into electronics, it is often without an oscilloscope. And one is left fumbling, both physically and mentally. Observing an electrical signal on a screen for the first time is a revelation. Nobody wishes to forgo that marvel again. There is no turning back. In electronics, if one wishes to progress with both enjoyment and understanding, an oscilloscope is essential. This marks the beginning of a period of questioning: how to choose one? And no sooner is that question answered than a whole string of others arises, which can be summed up in just one: how does one use the oscilloscope in such a way that what it displays truly reflects the reality of the signals? Rémy Mallard is a passionate communicator with a gift for making complex technical subjects understandable and engaging. In this book, he provides clear answers to essential questions about using an oscilloscope and offers a wealth of guidance to help readers explore and understand the electrical signals behind electronic systems. With his accessible style and practical insights, this book is a valuable tool for anyone eager to deepen their understanding of electronics.

Projects with Thonny-IDE, uPyCraft-IDE, and ESP32 The 'Python' programming language has enjoyed an enormous upswing in recent years. Not least, various single-board systems such as the Raspberry Pi have contributed to its popularity. But Python has also found widespread use in other fields, such as artificial intelligence (AI) or machine learning (ML). It is obvious, therefore, to use Python or the 'MicroPython' variant for use in SoCs (Systems on Chip) as well. Powerful controllers such as the ESP32 from Espressif Systems offer excellent performance as well as Wi-Fi and Bluetooth functionality at an affordable price. With these features, the Maker scene has been taken by storm. Compared to other controllers, the ESP32 has a significantly larger flash and SRAM memory, as well as a much higher CPU speed. Due to these characteristics, the chip is not only suitable for classic C applications, but also for programming with MicroPython. This book introduces the application of modern one-chip systems. In addition to the technical background, the focus is on MicroPython itself. After the introduction to the language, the programming skills learned are immediately put into practice. The individual projects are suitable for use in the laboratory as well as for everyday applications. So, in addition to the actual learning effect, the focus is also on the joy of building complete and useful devices. By using laboratory breadboards, circuits of all kinds can be realized with little effort, turning the testing and debugging of the 100% homebrew projects into an instructive pleasure. The various applications, such as weather stations, digital voltmeters, ultrasound range finders, RFID card readers or function generators, make the projects presented ideally suited for practical courses or subject and study work in the natural sciences, or in science and technology classes.

If you can describe it, you can build it AI coding assistants are changing what makers and solopreneurs can build. Tasks that once demanded weeks of learning a new language, framework, or software stack can now be delegated to an AI—provided you know how to describe the job, judge the result, and keep control of the process. The Maker’s Guide to AI Coding is a practical guide to doing exactly that. It explains how to work with AI coding tools as collaborators rather than vending machines, how much to delegate, how to write specifications that produce useful results, and how to recognise hallucinations, context drift, overconfidence, and code that runs but is still wrong. The book is built around four increasingly ambitious projects. You begin with a browser-based RC filter analyser, then develop a live serial data plotter for Arduino and other microcontrollers. Next comes a datasheet questionand- answer tool using retrieval-augmented generation (RAG), followed by a complete multi-user resource booking system with authentication, a database, external services, background jobs, and deployment. No advanced programming background is required. The emphasis is on thinking clearly, guiding the AI, testing what it produces, and preserving the skills needed to evaluate its work. Along the way, you learn development workflow designed to remain useful as tools evolve. If you can describe what you want to build, this book shows you how to turn that description into working software.

Verstehen und effektiv einsetzen Was in der Elektronik geschieht, ist mit bloßem Auge unsichtbar. Das Instrument, mit dem sich elektrische Signale präzise visualisieren lassen und die Effekte der Elektronik für uns sichtbar werden, ist das Oszilloskop. Leider wagt man sich beim Einstieg in die Elektronik oft ohne Oszilloskop vor. Man tappt dann im Dunkeln, sowohl praktisch als auch gedanklich. Die erste Beobachtung eines elektrischen Signals auf einem Bildschirm ist eine Offenbarung. Niemand möchte dieses Erlebnis danach noch einmal missen. Es gibt kein Zurück mehr. Wer in der Elektronik mit Freude und Verständnis vorankommen möchte, braucht unbedingt ein Oszilloskop. Dann stellt sich zunächst die Frage: Wie wählt man das richtige Oszilloskop aus? Und kaum ist diese Frage beantwortet, tauchen bereits die nächsten auf, die sich letztlich auf eine zentrale Frage reduzieren lassen: Wie nutzt man das Oszilloskop so, dass die Anzeige die Realität der Signale korrekt widerspiegelt? Rémy Mallard ist ein leidenschaftlicher Vermittler komplexer technischer Themen mit dem Talent, diese verständlich und fesselnd zu präsentieren. In diesem Buch beantwortet er wichtige Fragen zur Verwendung eines Oszilloskops und bietet zahlreiche Anleitungen, um die elektrischen Signale elektronischer Systeme zu erforschen und zu verstehen. Dank seines verständlichen Stils und seiner praktischen Einblicke ist dieses Buch ein wertvolles Werkzeug für alle, die ihr Elektronikwissen vertiefen möchten.
