C++ mit Visual Studio 2022 und Windows Forms-Anwendungen
Dieses Buch stellt C++ umfassend dar. Zahlreiche Beispiele veranschaulichen die Theorie. Dabei werden die Neuerungen von C++11, C++14 und C++17 von Anfang an integriert und ihre Vorteile gezeigt. Im Unterschied zu den allermeisten anderen C++-Büchern werden Windows-Programme mit einer grafischen Benutzeroberfläche entwickelt.Dieses Buch ist ein Lehrbuch, das sich an Studenten von Fachhochschulen und Universitäten richtet. Da es keine Vorkenntnisse voraussetzt, ist es auch zum Selbststudium geeignet. Es entstand aus zahlreichen Vorlesungen und Firmenseminaren. Der Aufbau, die Beispiele und Übungsaufgaben sind erprobt und bewährt.Und es ist gleichzeitig auch ein Fachbuch, das erfahrene C++-Programmierer auf den Stand von C++17 bringt. Es zeigt, wie die zahlreichen Neuerungen selbst elementare Programmiertechniken einfacher und sicherer machen. Dazu kommen neue Konzepte, die bessere und effizientere Lösungen als noch vor einigen Jahren ermöglichen. Viele dieser neuen Möglichkeiten sind in der industriellen Praxis noch nicht verbreitet.Übungsaufgaben ermöglichen dem Leser, das Gelernte zu vertiefen. Lösungen stehen auf www.rkaiser.de zum Download bereit.Dieses Buch erscheint in zwei weitgehend identischen Ausgaben:• In der vorliegenden Ausgabe werden Programme mit einer grafischen Benutzeroberfläche geschrieben, in denen alle Ein- und Aus-gaben über eine Windows-Benutzeroberfläche erfolgen.• In der anderen Ausgabe „C++ mit Visual Studio 2019“ (ISBN 978-3-662-594759) werden C++-Programme ohne eine grafische Benutzeroberfläche geschrieben. Alle Ein- und Ausgaben erfolgen mit cin und cout über die Konsole.Nach seinem Mathematikstudium an der Universität Tübingen war RICHARD KAISER einige Jahre in der Lehrerausbildung tätig, Trainer in der Industrie, Software-Entwickler (vor allem für technische Anwendungen) und Leiter der Software-Abteilung. Seit 1991 ist er Professor an der Dualen Hochschule Baden-Württemberg (Lörrach), wo er vor allem Vorlesungen über Programmiersprachen (C/C++/C#) und Mathematik hält. In den letzten Jahren hat er viele Seminare über C++ und C# für Firmen durchgeführt.Die Entwicklungsumgebung.- Steuerelemente für die Benutzeroberfläche.- Elementare Datentypen und Anweisungen in C und C++.- Sie Stringklassen string und wstring.- Arrays und Container.- Einfache selbstdefinierte Datentypen.- Zeiger, Strings und dynamisch erzeugte Variablen.- Überladene Funktionen und Operatoren.- Objektorientierte Programmierung.- Namensbereiche.- Exception-Handling.- Containerklassen der C++-Standardbibliothek.- Dateibearbeitung mit den Stream-Klassen.- Funktionsobjekte und Lambda-Ausdrücke.- Templates und STL.- C++11 Smart Pointer: shared_ptr, unique_ptr und weak_ptr.- Literatur.- Index.
STM32 - Das umfassende Praxisbuch (2. Auflg.)
ARM-Microcontroller programmieren für Embedded Systems - Das umfassende PraxisbuchMit diesem Buch erhalten Sie einen umfassenden Praxiseinstieg für die Softwareentwicklung für Embedded Systems mit der ARM-Mikrocontrollerfamilie STM32F4xx der Firma STMicroelectronics (STM). Für die Programmierung wird die Sprache C eingesetzt.Der Autor behandelt die wichtigsten Peripherie-Komponenten, dazu gehören digitale und analoge I/O-Ports (GPIOs), Timer und Counter, serielle Schnittstellen (USARTs/UARTs, SPI und I2C), ADCs und DACs, RTC (Echtzeit-Uhr) sowie Direct Memory Access (DMA).Die Programmierung dieser Komponenten zeigt der Autor anhand einfacher praktischer Anwendungsbeispiele wie z.B. die Abfrage von Uhrzeit und Datum von einer externen RTC (über I2C) sowie deren Anzeige über SPI auf einfachen Displays. Dabei entsteht im Verlauf des Buchs eine Bibliothek, deren Funktionen für eigene Projekte auf einfache Weise eingesetzt werden können.Als Entwicklungsumgebung wird STM32CubeIDE von STM verwendet. Außerdem kommt das Evaluierungsboard NUCLEO-64 für den STM32F446 zum Einsatz. Der Autor legt Wert darauf, alles »bare-metal« zu programmieren und verzichtet darauf, die HAL-Bibliothek einzusetzen. Diese Vorgehensweise erleichtert Ihnen auch den Umstieg auf Mikrocontroller anderer Hersteller. Grundlegende Kenntnisse der Programmiersprache C werden vorausgesetzt. Dennoch wird auf einige Aspekte eingegangen, die in der Bare-metal-Programmierung von Mikrocontrollern möglicherweise wichtiger sind als in der Entwicklung herkömmlicher PC-basierter Software.Aus dem Inhalt: Typische GPIO-Anwendungen (Input/Output/Alternative Funktionen)Timer: Systick/Basic/General Purpose/Advanced Control TimerPWM: Dimmen von LEDs mit TimernA/D- und D/A-WandlungSerielle Kommunikation mit UARTs/USARTs/I2C/SPIPorterweiterung mit I2C (PCF8574)/Ansteuerung von LC-Displays7-Segment-Anzeigen über SPI (MAX7219)Einsatz einer externen Echtzeituhr (RTC) DS3231 über I2CAutor: Ralf Jesse ist Diplom-Ingenieur der Elektrotechnik mit mehr als 30 Jahren beruflicher Praxis im Einsatz von Mikroprozessoren und -controllern. Nach ersten Erfahrungen als Entwicklungsingenieur in einem Maschinenbau-Unternehmen folgten mehr als 20 Jahre als Software-Ingenieur in einem großen japanischen Konzern.

Develop and Operate Your LoRaWAN IoT Nodes
LoRaWAN has developed excellently as a communication solution in the IoT. The Things Network (TTN) has contributed to this. The Things Network was upgraded to The Things Stack Community Edition (TTS (CE)). The TTN V2 clusters were closed towards the end of 2021.In this book, I will show you the necessary steps to operate LoRaWAN nodes using TTS (CE) and maybe extend the network of gateways with an own gateway. Meanwhile, there are even LoRaWAN gateways suitable for mobile use with which you can connect to the TTN server via your cell phone.I present several commercial LoRaWAN nodes and new, low-cost and battery-powered hardware for building autonomous LoRaWAN nodes.Registering LoRaWAN nodes and gateways in the TTS (CE), providing the collected data via MQTT and visualization via Node-RED, Cayenne, Thingspeak, and Datacake enable complex IoT projects and completely new applications at very low cost.This book will enable you to provide and visualize data collected with battery-powered sensors (LoRaWAN nodes) wirelessly on the Internet. You will learn the basics for smart city and IoT applications that enable, for example, the measurement of air quality, water levels, snow depths, the determination of free parking spaces (smart parking), and the intelligent control of street lighting (smart lighting), among others.Dr. Claus Kühnel studied information technology at the Technical University of Dresden. He has developed embedded systems for laboratory diagnostic devices, among others. In this interdisciplinary field he came in touch with the maker scene.

The Definitive Guide to Security in Jakarta EE
Refer to this definitive and authoritative book to understand the Jakarta EE Security Spec, with Jakarta Authentication & Authorization as its underlying official foundation. Jakarta EE Security implementations are discussed, such as Soteria and Open Liberty, along with the build-in modules and Jakarta EE Security third-party modules, such as Payara Yubikey & OIDC, and OmniFaces JWT-Auth.The book discusses Jakarta EE Security in relation to SE underpinnings and provides a detailed explanation of how client-cert authentication over HTTPS takes place, how certifications work, and how LDAP-like names are mapped to caller/user names. General (web) security best practices are presented, such as not storing passwords in plaintext, using HTTPS, sanitizing inputs to DB queries, encoding output, and explanations of various (web) attacks and common vulnerabilities are included.Practical examples of securing applications discuss common needs such as letting users explicitly log in, sign up, verify email safely, explicitly log in to access protected pages, and go direct to the log in page. Common issues are covered such as abandoning an authentication dialog halfway and later accessing protected pages again.WHAT YOU WILL LEARN* Know what Jakarta/Java EE security includes and how to get started learning and using this technology for today's and tomorrow's enterprise Java applications* Secure applications: traditional server-side web apps built with JSF (Faces) as well as applications based on client-side frameworks (such as Angular) and JAX-RS* Work with the daunting number of security APIs in Jakarta EE* Understand how EE security evolvedWHO THIS BOOK IS FORJava developers using Jakarta EE and writing applications that need to be secured (every application).
