Einführung in die SPS-Programmierung mit dem Open-Source-Projekt auf dem Raspberry Pi und Modbus-Beispiele mit dem Arduino Uno und ESP8266 Die SPS-Programmierung ist heute in der Industrie und in der Hausautomation sehr weit verbreitet. In diesem Buch beschreibt der Autor, wie der Raspberry Pi 4 als SPS eingesetzt werden kann. Angefangen mit der Softwareinstallation auf dem Raspberry Pi und dem SPS-Editor auf dem PC geht es nach einer Beschreibung der Hardware an das Programmieren. Es folgen interessante Beispiele nach IEC 61131-3 in den verschiedenen Programmiersprachen. Ausführlich wird auch erklärt, wie der SPS-Editor benutzt wird und wie die Programme auf den Raspberry Pi geladen und ausgeführt werden. Angefangen mit der Programmierung mit KOP (Kontaktplan) über ST (Structured Control Language) bis zu AS (Special Function Chart) werden alle IEC-Sprachen mit Beispielen behandelt. Diese können auf der Website des Autors heruntergeladen werden. Auch die Vernetzung kommt nicht zu kurz. Der Arduino Uno und der ESP8266 werden als ModbusRTU- bzw. ModbusTCP-Module programmiert, um Zugriff auf externe Peripherie zu erhalten. Damit ist es möglich, Sensoren einzulesen und Verbraucher zu schalten. Interessant dürften auch E/A-Schaltungen sein, die dem 24V-Industriestandard entsprechen. Befehlsübersichten für ST und KOP runden das Buch ab. Nach dem Durcharbeiten des Buches ist der Leser in der Lage, eigene SPS-Steuerungen mit dem Raspberry Pi zu verwirklichen.

Projects Using Arduino IDE and the LVGL Graphics Library The ESP32 is probably one of the most popular microcontrollers used by many people, including students, hobbyists, and professional engineers. Its low cost, coupled with rich features makes it a popular device to use in many projects. Recently, a board called the ESP32 Cheap Yellow Display (CYD for short) is available from its manufacturers. The board includes a standard ESP32 microcontroller together with a 320x240 pixel TFT display. Additionally, the board provides several connectors for interfaces such as GPIO, serial port (TX/RX), power and Ground. The inclusion of a TFT display is a real advantage as it enables users to design complex graphics-based projects without resorting to an external LCD or graphics displays. The book describes the basic hardware of the ESP32 CYD board and provides details of its on-board connectors. Many basic, simple, and intermediate-level projects are given in the book based on the ESP32 CYD, using the highly popular Arduino IDE 2.0 integrated development environment. The use of both the basic graphics functions and the use of the popular LVGL graphics library are discussed in the book and projects are given that use both types of approaches. All the projects given in the book have been tested and are working. The block diagram, circuit diagram, and the complete program listings and program descriptions of all the projects are given with explanations. Readers can use the LVGL graphics library to design highly popular eye-catching full-color graphics projects using widgets such as buttons, labels, calendars, keypads, keyboards, message boxes, spinboxes, sliders, charts, tables, menus, bars, switches, drop-down lists, animations, and many more widgets.

EAGLE – the “Easily Applicable Graphical Layout Editor“ is a professional-grade CAD (computer aided design) software package for the design and drafting of electronic schematics as well as the design and fabrication of printed circuit boards (PCBs). This Advanced User Guide provides the experienced EAGLE user with insight into using some of the more advanced features of EAGLE software. It is not a guide to teach the reader the basic concepts of EAGLE, nor does it discuss the ‘how to’ of the EAGLE interface and the simpler operations and commands of the software. That is the purpose of the author’s previous title EAGLE V6 Getting Started Guide also published by Elektor. This eBook is intended as an enduring document covering the more advanced modules, commands, and functions which make up EAGLE. It is hoped that this eBook will provide a quick, succinct reference to assist with more complex applications and uses of EAGLE – an ‘EAGLE User’s Companion’, if you like. Complementing the EAGLE Advanced User Guide, the EAGLE User Language manual is included in this eBook in unabridged form, reproduced with permission of CadSoft GmbH. At the time of writing, the material in this eBook covers version 7 of the EAGLE software suite.
