Die Programmiersprache „Python“ hat in den letzten Jahren einen enormen Aufschwung erlebt. Nicht zuletzt haben verschiedene Einplatinensysteme wie der Raspberry Pi zu deren Bekanntheitsgrad beigetragen. Aber auch in anderen Gebieten, wie der Künstlichen Intelligenz oder dem Machine Learning, hat Python weite Verbreitung gefunden. Es ist daher naheliegend, Python bzw. die Variante „MicroPython“ auch für den Einsatz in SoCs (Systems on Chip) zu verwenden. Leistungsfähige Controller wie der ESP32 der Firma Espressif Systems bieten eine hervorragende Performance sowie Wi-Fi- und Bluetooth-Funktionalität zu einem günstigen Preis. Mit diesen Eigenschaften wurde die Maker-Szene im Sturm erobert. Im Vergleich zu anderen Controllern weist der ESP32 einen deutlich größeren Flash und SRAM-Speicher, sowie eine wesentlich höhere CPU-Geschwindigkeit auf. Aufgrund dieser Leistungsmerkmale eignet sich der Chip nicht nur für klassische C-Anwendungen, sondern insbesondere auch für die Programmierung mit MicroPython. Das vorliegende Buch führt in die Anwendung der modernen Ein-Chip-Systeme ein. Neben den technischen Hintergründen steht vor allem MicroPython selbst im Vordergrund. Nach der Einführung in die Sprache werden die erlernten Programmierkenntnisse umgehend in die Praxis umgesetzt. Die einzelnen Projekte sind sowohl für den Einsatz im Labor als auch für Alltagsanwendungen geeignet. Neben dem eigentlichen Lerneffekt steht also auch die Freude am Aufbau kompletter und nützlicher Geräte im Vordergrund. Durch die Verwendung von Laborsteckboards können Schaltungen aller Art mit geringem Aufwand realisiert werden, sodass das Austesten der selbstgebauten Geräte zum lehrreichen Vergnügen wird. Durch die verschiedenen Anwendungen wie Wetterstationen, Digitalvoltmeter, Ultraschall-Entfernungsmesser, RFID-Kartenleser oder Funktionsgeneratoren sind die vorgestellten Projekte auch für Praktika oder Fach- und Studienarbeiten in den Naturwissenschaften bzw. im Natur- und Technikunterricht bestens geeignet.

This book is intended as a highly-practical guide for Hobbyists, Engineers and Scientists wishing to build measurement and control systems to be controlled by a local or remote Personal Computer running the Linux operating system. Both hardware and software aspects of designing typical embedded systems are covered in detail with schematics, code listings and full descriptions. Numerous examples have been designed to show clearly how straightforward it can be to create the interfaces between digital and analog electronics, with programming techniques for creating control software for both local and remote systems. Hardware developers will appreciate the variety of circuits, including a novel, low cost modulated wireless link and will discover how using Matlab® overcomes the need for specialist programming skills. Software developers will appreciate how a better understanding of circuits plus the freedom offered by Linux to directly control at the register level enables them to optimize related programs. There is no need to buy special equipment or expensive software tools in order to create embedded projects covered in this book. You can build such quality systems quickly using popular low-cost electronic components and free distributed or low-cost software tools. Some knowledge of basic electronics plus the very basics of C programming only is required. Many projects in this book are developed using Matlab® being a very popular worldwide computational tool for research in engineering and science. The book provides a detailed description of how to combine the power of Matlab® with practical electronics. With an emphasis on learning by doing, readers are encouraged by examples to program with ease; the book provides clear guidelines as to the appropriate programming techniques “on the fly”. Complete and well-documented source code is provided for all projects. If you want to learn how to quickly build Linux-based applications able to collect, process and display data on a PC from various analog and digital sensors, how to control circuitry attached to a computer, then even how to pass data via a network or control your embedded system wirelessly and more – then this is the book for you! Features of this Book Use the power, flexibility and control offered only by a Linux operating system on a PC. Use a free, distributed downloadable GNU C compiler Use (optional) a low-cost Student Version of Matlab®. Use low-cost electronic sub-assemblies for projects.

Developing CoAP applications for Thread networks with Zephyr This book will guide you through the operation of Thread, the setup of a Thread network, and the creation of your own Zephyr-based OpenThread applications to use it. You’ll acquire knowledge on: The capture of network packets on Thread networks using Wireshark and the nRF Sniffer for 802.15.4. Network simulation with the OpenThread Network Simulator. Connecting a Thread network to a non-Thread network using a Thread Border Router. The basics of Thread networking, including device roles and types, as well as the diverse types of unicast and multicast IPv6 addresses used in a Thread network. The mechanisms behind network discovery, DNS queries, NAT64, and multicast addresses. The process of joining a Thread network using network commissioning. CoAP servers and clients and their OpenThread API. Service registration and discovery. Securing CoAP messages with DTLS, using a pre-shared key or X.509 certificates. Investigating and optimizing a Thread device’s power consumption. Once you‘ve set up a Thread network with some devices and tried connecting and disconnecting them, you’ll have gained a good insight into the functionality of a Thread network, including its self-healing capabilities. After you’ve experimented with all code examples in this book, you’ll also have gained useful programming experience using the OpenThread API and CoAP.

Clever Tricks with ATmega328 Pro Mini Boards With a simple Pro Mini board and a few other components, projects that 20 or 30 years ago were unthinkable (or would have cost a small fortune) are realized easily and affordably in this book: From simple LED effects to a full battery charging and testing station that will put a rechargeable through its paces, there’s something for everyone. All the projects are based on the ATmega328 microcontroller, which offers endless measuring, switching, and control options with its 20 input and output lines. For example, with a 7-segment display and a few resistors, you can build a voltmeter or an NTC-based thermometer. The Arduino platform offers the perfect development environment for programming this range of boards. Besides these very practical projects, the book also provides the necessary knowledge for you to create projects based on your own ideas. How to measure, and what? Which transistor is suitable for switching a certain load? When is it better to use an IC? How do you switch mains voltage? Even LilyPad-based battery-operated projects are discussed in detail, as well as many different motors, from simple DC motors to stepper motors. Sensors are another exciting topic: For example, a simple infrared receiver that can give disused remote controls a new lease on life controlling your home, and a tiny component that can actually measure the difference in air pressure between floor and table height!

The software simulation of gauges, control-knobs, meters and indicators which behave just like real hardware components on a PC’s screen is known as virtual instrumentation. In this book, the Delphi program is used to create these mimics and PIC based external sensors are connected via a USB/RS232 converter communication link to a PC. Detailed case studies in this Book include a virtual compass displayed on the PC’s screen, a virtual digital storage oscilloscope, virtual -50 to +125 degree C thermometer, and FFT sound analyser, a joystick mouse and many examples detailing virtual instrumentation Delphi components. Arizona’s embedded microcontrollers – the PIC's are used in the projects and include PIC16F84A, PIC16C71, DSPIC30F6012A, PIC16F877, PIC12F629 and the PIC16F887. Much use is made of Microchip’s 44 pin development board (a virtual instrument ‘engine)’, equipped with a PIC16F887 with an onboard potentiometer in conjunction with the PIC’s ADC to simulate the generation of a variable voltage from a sensor/transducer, a UART to enable PC RS232 communications and a bank of 8 LED's to monitor received data is also equipped with an ISP connector to which the ‘PICKIT 2’ programmer may easily be connected. Full source code examples are provided both for several different PIC’s, both in assembler and C, together with the Pascal code for the Delphi programs which use different 3rd party Delphi virtual components.
