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

Programming the Finite State Machine with 8-Bit PICs in Assembly and C Andrew Pratt provides a detailed introduction to programming PIC microcontrollers, as well as a thorough overview of the Finite State Machine (FSM) approach to programming. Most of the book uses assembly programming, but do not be deterred. The FSM gives a structure to a program, making it easy to plan, write, and modify. The last two chapters introduce programming in C, so you can make a direct comparison between the two techniques. The book references the relevant parts of the Microchip datasheet as familiarity with it is the best way to discover detailed information. This book is aimed at Microsoft Windows and Linux users. To keep your costs to a minimum and to simplify the toolchain, specific applications are provided as a free download to enable you to use an FTDI serial lead as the programmer. The assembler used is the open-source "gpasm". All programming can be done in a text editor. There are detailed instructions on how to perform the necessary installations on Windows, Linux Debian, and derivatives such as Ubuntu and Fedora. For programming in C, Microchip's XC8 compiler is used from the command line. In addition to the programming applications, two serial read and serial write applications can be used for communicating with the PICs from a computer. A voltmeter project including practical instructions on building a circuit board from scratch is included. All theory is covered beforehand, including how to do integer arithmetic in assembly. Two PICs are covered: the PIC12F1822 and the PIC16F1823. Both can run at 32 MHz with an internal oscillator. You do not need to buy a factory-made development board and programmer. With relatively inexpensive parts including a serial lead, microcontroller, a few resistors, and LEDs, you can get started exploring embedded programming. Links Updated Programmer

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.
