PIC und AVR verstehen In diesem Buch werden wir uns ausschließlich mit 8-Bit-Mikrocontrollern beschäftigen, und zwar mit Mikrocontrollern der 8-Bit-PIC- und der 8-Bit-AVR-Mikrocontroller-Linien. Bei der PIC-Familie handelt es sich dabei um PIC10, PIC12, PIC16 und PIC18; bei der AVR-Familie um ATtiny, ATmega und ATxmega. Die vorgestellten 8-Bit-Chips sind für sehr viele Anwendungen vollkommen ausreichend und preislich auch attraktiv. Durch die Lektüre des Buches erhalten Sie ein fundiertes Wissen über die genannten 8-Bit-Mikrocontroller, über ihre Architektur, ihre Pinbelegungen und über ihre Programmierung. Weil wir uns in diesem Buch mit den Grundlagen der Architektur der PICs und AVRs vertraut machen möchten, werden wir auch für alle PIC- und AVR-Anwendungen Assembler einsetzen, denn die Assembler-Sprache erlaubt es, die Technik im Detail kennenzulernen. Wenn man wirklich wissen möchte, was sich im Mikrocontroller abspielt, greift man zu Assembler. Damit hat man die beste Gelegenheit, sehr nah an den Kern zu kommen. Und wenn man schon einen Mikrocontroller-Typ kennengelernt und verstanden hat, ist es bei dem nächsten deutlich einfacher, auch wenn er von einem anderen Hersteller kommt. Bei anderen Programmiersprachen bleibt die Technik immer ziemlich tief versteckt. Die Assembler-Beispiele sind so einfach gestaltet, dass sie jeder mit den im Buch aufgezeigten Programmiertechniken erstellen kann. Weil es sich um einfache Beispiele handelt, werden wir sie alle auf einer universellen Lochrasterplatine realisieren. Manche sind auch auf einem Experimentier-Breadboard umsetzbar.

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.

Using the RFID Starter Kit An Arduino board has now become ‘the’ basic component in the maker community. No longer is an introduction to the world of microcontrollers the preserve of the expert. When it comes to expanding the capabilities of the basic Arduino board however, the developer is still largely on his own. If you really want to build some innovative projects it’s often necessary to get down to component level. This can present many beginners with major problems. That is exactly where this book begins. This book explains how a wide variety of practical projects can be built using items supplied in a single kit together with the Arduino board. This kit, called the 'RFID Starter Kit for Arduino' (SKU 17240) is not just limited to RFID applications but contains more than 30 components, devices and modules covering all areas of modern electronics. In addition to more simple components such as LEDs and resistors there are also complex and sophisticated modules that employ the latest technology such as: A humidity sensor A multicolor LED A large LED matrix with 64 points of light A 4-character 7-segment LED display An infra red remote-controller unit A complete LC-display module A servo A stepper motor and controller module A complete RFID reader module and security tag On top of that you will get to build precise digital thermometers, hygrometers, exposure meters and various alarm systems. There are also practical devices and applications such as a fully automatic rain sensor, a sound-controlled remote control system, a multifunctional weather station and so much more. All of the projects described can be built using the components supplied in the Elektor kit.
