Microcontrollers have become an indispensable part of modern electronics. They make things possible that vastly exceed what could be done previously. Innumerable applications show that almost nothing is impossible. There’s thus every reason to learn more about them, but that raises the question of where to find a good introduction to this fascinating technology. The answer is easy: this Microcontroller Basics book, combined with the 89S8252 Flash Board project published by Elektor Electronics. However, this book offers more than just a basic introduction. It clearly explains the technology using various microcontroller circuits and programs written in several different programming languages. Three microcontrollers from the 8051 family are used in the sample applications, ranging from the simple 89C2051 to the AN2131, which is designed to support USB applications. The programming tools include assemblers, Basic-52 and BASCOM-51, and several C compilers. Every reader can thus find the programming environment most suitable to his or her needs. In the course of the book, the reader gradually develops increased competence in converting his or her ideas into microcontroller circuitry. All of the sample programs can be downloaded from the Elektor Electronics website or the author’s website. That has the added advantage that the latest versions are always available.

In this book the author presents all essential aspects of microcontroller programming, without overloading the reader with unnecessary or quasi-relevant bits of information. Having read the book, you should be able to understand as well as program, 8-bit microcontrollers. The introduction to microcontroller programming is worked out using microcontrollers from the PIC series. Not exactly state-of-the-art with just 8 bits, the PIC micro has the advantage of being easy to comprehend. It is offered in a DIP enclosure, widely available and not overly complex. The entire datasheet of the PIC micro is shorter by decades than the description of the architecture outlining the processor section of an advanced microcontroller. Simplicity has its advantages here. Having mastered the fundamental operation of a microcontroller, you can easily enter into the realms of advanced softcores later. Having placed assembly code as the executive programming language in the foreground in the first part of the book, the author reaches a deeper level with ‘C’ in the second part. Cheerfully alongside the official subject matter, the book presents tips & tricks, interesting measurement technology, practical aspects of microcontroller programming, as well as hands-on options for easier working, debugging and faultfinding.

If you have the right tools, designing a microprocessor shouldn’t be complicated. The Verilog hardware description language (HDL) is one such tool. It can enable you to depict, simulate, and synthesize an electronic design, and thus increase your productivity by reducing the overall workload associated with a given project.Monte Dalrymple’s Microprocessor Design Using Verilog HDL is a practical guide to processor design in the real world. It presents the Verilog HDL in a straightforward fashion and serves as a detailed introduction to reducing the computer architecture and as an instruction set to practice. You’re led through the microprocessor design process from start to finish, and essential topics ranging from writing in Verilog to debugging and testing are laid bare.The book details the following, and more: Verilog HDL Review: data types, bit widths/labeling, operations, statements, and design hierarchy Verilog Coding Style: files vs. modules, indentation, and design organization Design Work: instruction set architecture, external bus interface, and machine cycle Microarchitecture: design spreadsheet and essential worksheets (e.g., Operation, Instruction Code, and Next State) Writing in Verilog: choosing encoding, assigning states in a state machine, and files (e.g., defines.v, hierarchy.v, machine.v) Debugging, Verification, and Testing: debugging requirements, verification requirements, testing requirements, and the test bench Post Simulation: enhancements and reduction to practice Monte Dalrymple received a BSEE (with highest honors) and an MSEE from the University of California at Berkeley, where he was elected to Phi Beta Kappa. Monte started his career at Zilog, where he designed a number of successful products, including the Serial Communication Controller (SCC) family and the Universal Serial Controller (USC) family. He was also the architect and lead designer of the Z380 microprocessor. Monte started his own company, Systemyde International Corp., in 1995, and has been doing contract design work ever since. He designed all five generations of Rabbit microprocessors, a Z180 clone that is flying on the Juno mission to Jupiter, and a Z8000 clone that flies in a commercial avionics air data computer. Monte holds 16 patents as well as both amateur and commercial radio licenses. Monte wrote 10 articles for Circuit Cellar magazine between 1996 and 2010. He recently completed a side project to replace the CPU in an HP-41C calculator with a modern FPGA-based version.

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.

Valve Amplifiers are regarded by many to be the ne plus ultra when it comes to processing audio signals. The combination of classical technology and modern components has resulted in a revival of the valve amplifier. The use of toraidal-core output transformers, developed by the author over the past 15 years, has contributed to this revival. The most remarkable features of these transformers are their extremely wide frequency ranges and their very low levels of linear and nonlinear distortion. This book explains the whys and wherefores of toroidal output transformers at various technical levels, starting with elementary concepts and culminating in complete mathematical descriptions. In all of this, the interactions of the output valves, transformer and loudspeaker form the central theme. Next come the practical aspects. The schematic diagram of a valve amplifier often appears to be very simple at first glance, but anyone who has built a modern valve amplifier knows that a lot of critical details are hidden behind this apparent simplicity. These are discussed extensively, in connection with designs for amplifiers with output powers ranging from 10 to 100 watts. Finally, the author gives some attention to a number of special valve amplifiers, and to the theory and practice of negative feedback. In summary, this book offers innovative solutions for achieving perfect audio quality. Do-it-yourself builders, as well as persons who want to gain a deeper technical understanding of the complex world of audio transformers, valve amplifiers and audio signal processing, will find this book a rich and useful source of information.

Architecture, Programming and Applications The MSP430 is a popular family of microcontrollers from Texas Instruments. In this book we will work with the smallest type, which is the powerful MSP430G2553. We will look at the capabilities of this microcontroller in detail, as it is well-suited for self-made projects because it is available in a P-DIP20 package. We will take a closer look at the microcontroller and then build, step by step, some interesting applications, including a 'Hello World' blinking LED and a nice clock application, which can calculate the day of the week based on the date. You also will learn how to create code for the MSP microcontroller in assembler. In addition to that, we will work with the MSP-Arduino IDE, which makes it quite easy to create fast applications without special in-depth knowledge of the microcontrollers. All the code used in the book is available for download from the Elektor website.

Multitasking and multiprocessing have become a very important topic in microcontroller-based systems, namely in complex commercial, domestic, and industrial automation applications. As the complexity of projects grows, more functionalities are demanded from the projects. Such projects require the use of multiple inter-related tasks running on the same system and sharing the available resources, such as the CPU, memory, and input-output ports. As a result of this, the importance of multitasking operations in microcontroller-based applications has grown steadily over the last few years. Many complex automation projects now make use of some form of a multitasking kernel. This book is project-based and its main aim is to teach the basic features of multitasking using the Python 3 programming language on Raspberry Pi. Many fully tested projects are provided in the book using the multitasking modules of Python. Each project is described fully and in detail. Complete program listings are given for each project. Readers should be able to use the projects as they are, or modify them to suit their own needs. The following Python multitasking modules have been described and used in the projects: Fork Thread Threading Subprocess Multiprocessing The book includes simple multitasking projects such as independently controlling multiple LEDs, to more complex multitasking projects such as on/off temperature control, traffic lights control, 2-digit, and 4-digit 7-segment LED event counter, reaction timer, stepper motor control, keypad based projects, car park controller, and many more. The fundamental multitasking concepts such as process synchronization, process communication, and memory sharing techniques have been described in projects concerning event flags, queues, semaphores, values, and so on.
