Grafisch programmieren, messen und steuern mit Processing
Ein Blick in die einschlägigen Internetforen zeigt, dass das Programmieren immer noch in der Gruppe der beliebten Hobbys rangiert. Wo dem Hobbyprogrammierer früher eine Reihe bekannter und populärer Programmiersprachen zur Verfügung standen, ist es heute relativ übersichtlich geworden: Außer C++, Java und Visual Basic gibt es wenig bekannte und beliebte Programmiersprachen. Was fehlt, ist eine Programmiersprache, die für Laien fast so einfach zu handhaben ist wie die alten BASIC-Versionen, deren Leistung und Features dennoch an die Möglichkeiten und die Power moderner Windows-Rechner angepasst sind. Diese Programmiersprache existiert und heißt Processing.Das vorliegende Buch führt den Leser in diese visuelle Programmiersprache ein. Das Buch richtet sich an Leser, die bereits allgemeine Erfahrungen im Umgang mit Programmiersprachen besitzen und wissen, worum es sich bei Strings, Arrays oder Schleifen handelt. Der Autor zeigt anhand vieler kurzer Programmbeispiele, wie einfach es ist, mit Processing auch leistungsfähige Software zu programmieren und sich dabei auf eine nur geringe Anzahl von Befehlen, Anweisungen und Funktionen zu beschränken.Die in diesem Buch vorgestellten Programme sind zum Teil Hardware-orientiert, wobei auch die Erfassung von Daten und die Steuerung von Hardware mittels des bekannten Mikrocontrollers Arduino einer Rolle spielt. Kurz und gut: Ein Buch für alle, die eine schnell und einfach zu programmierende Software mit elektronischer Hardware kombinieren und das Ganze über maßgeschneiderte Benutzeroberflächen steuern möchten.Kurt Diedrich ist gelernter Geologe und gehört zu den langjährigen freien Mitarbeitern des ElektorVerlags. Neben dem nun schon seit über 25 Jahren erfolgreichen "Dauerbrenner" Operationsverstärker gar nicht schwer stammen auch verschiedene Bücher zum Thema Programmierung aus seiner Feder. Auf seiner Webseite www.subroutine. info veröffentlicht er in unregelmäßigen Abständen die neuesten Ergebnisse seiner Arbeit.
Programming the Finite State Machine with 8-Bit PICs in Assembly and C
This practical guide is aimed at electronics students and hobbyists. It is intended to be a valuable aid in writing programs using Finite State Machines (FSMs) in assembly language using 8-bit PIC microcontrollers. The last two chapters introduce the use of the C programming language and make a direct comparison with development in Assembly.An FSM is a way of writing a program to make it easier to produce and modify. The machine is abstract in that it is just the structure of the program. This abstract machine can be represented by drawing a diagram on paper. The diagram is independent of the programming language used. The FSM chart gives a complete description of what the program does. It can then be implemented as source code.The book should appeal to those with an interest in the combination of electronics and software and have an interest in how things work. The book will describe writing code for two particular microcontrollers: The 12F1822 and 16F1823. Both are mid-range and inexpensive. To read and write the programs to and from the PICs, all that is required is an FTDI TTL level USB lead (TTL-232R-5V-WE) in addition to two programs that are both available for free download as executable files and source code from Elektor. Microsoft Windows or Linux can be used.The PIC programs are written in assembly language. This goes against the conventional wisdom of using a higher-level language such as C. One reason for this is that assembly is a good way of learning what is happening at the lowest level. This is important as microcontroller programming requires an understanding of the chip. Another reason for using the finite state machine approach is that it makes assembly programs surprisingly easy to follow. One of the main obstacles in the way of getting started with embedded programming is the installation and learning of new software tools.The emphasis of this book is on making things straightforward with as little complication as possible. Therefore you can concentrate on understanding the code. Real projects aren't just about coding: our software has to do something real. As a consequence, a chapter deals with a method of circuit board construction.All coding is done in a text editor of your choosing. The command line is used for running programs. If you are a Windows user, you might look at this as old fashioned. This is actually an efficient way of doing things: simple scripts for repetitive tasks save lots of mouse clicks. The last two chapters give an introduction to programming in C using the XC8 compiler. Again this is done using a text editor and the command line.The intention has been to achieve results using an inexpensive microcontroller with simple command line tools. Much emphasis is placed on using Microchip's datasheet as this is the best place to get correct detailed informationAndrew Pratt served for 25 years in the Royal Air Force as an Aircraft Technician. He holds a Higher National Certificate in electrical and electronicengineering and an Honours Degree from the Open University. He continued his career working in industrial controls.

Arduino Software Internals
It’s not enough to just build your Arduino projects; it’s time to actually learn how things work! This book will take you through not only how to use the Arduino software and hardware, but more importantly show you how it all works and how the software relates to the hardware.Arduino Software Internals takes a detailed dive into the Arduino environment. We’ll cover the Arduino language, hardware features, and how makers can finally ease themselves away from the hand holding of the Arduino environment and move towards coding in plain AVR C++ and talk to the microcontroller in its native language.What You’ll Learn:* How the Arduino Language interfaces with the hardware, as well as how it actually works in C++;* How the compilation system works, and how kit can be altered to suit personal requirements;* A small amount of AVR Assembly Language;* Exactly how to set up and use the various hardware features of the AVR without needing to try and decode the data sheets – which are often bug ridden and unclear;* Alternatives to the Arduino IDE which might give them a better workflow;* How to build their own Arduino clone from scratch.Who This Book Is For:No expertise is required for this book! All you need is an interest in learning about what you’re making with Arduinos and how they work. This book is also useful for those looking to understand the AVR microcontroller used in the Arduino boards. In other words, all Makers are welcome! Norman Dunbar is an Oracle Database Administrator. Norman has had a long running relationship with Electronics since childhood and computers since the late 1970s, and the Arduino was a perfect marriage of the two interests. With a love of learning new things, examining and explaining the Arduino Language and the hardware became a bit of a hobby, and as piles of notes expanded, Norman has now decided to publish his work.1.

Beginning Game Programming with Pygame Zero
Make fun games while learning to code. Focused on making games rather than teaching programming theory, in this book you're more likely to see code on how gravity affects a missiles trajectory instead of the most efficient way to search through data. Even then the code is kept simple as games should be about playability rather than complex physics. There are links to the official documentation when you need to lookup information that isn't included in the book.Start with a simple text based game to grasp the basics of programming in Python. Then moves on to creating simple graphical games in Pygame Zero. Not only will you learn object oriented programming to make it easier to make more complex games, you'll also work to create your own graphics and sounds. 3D graphics are a little complex. So we focus on 2D games, including spins on some classic boardgames and arcade games. All the games are designed to run on a Raspberry Pi. They will work on any Raspberry Pi, but will also work on any other computer that supports Python 3 along with Pygame Zero.The games you make will be playable and hopefully fun to play. And by the end of the book, you can step beyond the provided source code to develop your own unique games and programs.WHAT YOU'LL LEARN* Code in Python* Generate sounds and graphics for 2D games* Grasp object oriented programming with Pygame Zero WHO THIS BOOK IS FORBeginning game developers interested in working with low-cost and easy-to-learn solutions like Pygame Zero and the Raspberry Pi.STEWART WATKISS is a keen maker, programmer, and author of Learn Electronics with Raspberry Pi.
