Raspberry Pi Foundation FPC Camera Cable for Raspberry Pi 5 (500 mm)
Raspberry Pi 5 provides two four-lane MIPI connectors, each of which can support either a camera or a display. These connectors use the same 22-way, 0.5 mm-pitch “mini” FPC format as the Compute Module Development Kit, and require adapter cables to connect to the 15-way, 1 mm-pitch “standard” format connectors on current Raspbery Pi camera and display products.These mini-to-standard adapter cables for cameras and displays (note that a camera cable should not be used with a display, and vice versa) are available in 200 mm, 300 mm and 500 mm lengths.

Elektor Digital Mikrocontroller-Module (PDF)
Grundlagen und Selbstbau Weshalb nicht damit beginnen, Mikrocontroller-Module selbst zu entwickeln, zumindest aber sich in Gedanken mit solchen Aufgaben zu beschäftigen? Wie Mikrocontroller-Module aufgebaut sind und wozu sie verwendet werden, soll in 'Mikrocontroller-Module – Grundlagen und Selbstbau' dargestellt werden. Das vorliegende Buch beleuchtet Mikrocontroller-Module, die vor allem zum Experimentieren, zum Lernen und zum Einarbeiten in die Entwicklung und Programmierung von Embedded Systems gedacht sind. Die Entwurfsgrundsätze, Lösungsvorschläge und Projekte, die in diesem Buch beschrieben werden, sind aus zwei Ideen hervorgegangen: Erstens können neue Entwicklungen zwischen den weit verbreiteten kostengünstigen Mikrocontroller-Modulen und der industriellen Computer- und Steuerungstechnik ihren Platz finden und zweitens ist es eine Herausforderung an sich, solche Module zu entwickeln und einzusetzen. In den ersten sieben Kapiteln dieses Buches werden die technischen Grundlagen diskutiert und anhand eigener Entwicklungen veranschaulicht. Das achte Kapitel gibt einen Überblick über diesen Modulbaukasten. Alle Fotos aus dem Buch können hier vierfarbig heruntergeladen werden.

Dit is een ideaal boek voor hobbyisten, studenten en ingenieurs die op een leuke manier C en het gebruik van een mbed ARM microcontroller willen leren, rechtstreeks op internet zonder ingewikkelde software-installatie. De projecten in dit boek zijn bedoeld voor gevorderden op het gebied van ARM microcontrollers of de programmeertaal C. Dat wil zeggen dat de kennis uit deel 1 van deze serie bekend verondersteld wordt. Cloud technologie De in dit boek gebruikte mbed NXP LPC1768 maakt gebruik van cloud-technologie, een revolutionair concept voor software-ontwikkeling. Dit houdt in dat u geen software hoeft te installeren om de mbed te kunnen programmeren! Het enige dat u nodig heeft, is een internet-browser zoals Microsoft Internet Explorer, en een USB-poort op uw PC. U kunt vanaf elke willekeurige PC waar dan ook ter wereld toegang krijgen tot uw project en er aan verder werken. Wanneer u klaar bent, kunt u met een paar eenvoudige klikjes met uw muis het programma overzetten naar uw mbed-hardware. Uiteraard kunt u de projecten ook downloaden en op uw eigen PC opslaan wanneer u dat liever heeft. In een deel van de projecten wordt Visual Basic gebruikt; dit gratis pakket is nog niet in de cloud beschikbaar en moet wel op uw PC geïnstalleerd worden. Onderwerpen die aan de orde komen Leer het programmeren van een ARM microcontroller via cloud-technologie. Geen ARM ontwikkelsoftware-installatie op uw eigen PC. Leer hoe u een ARM microcontroller met internet kunt verbinden, hoe u via internet uw ARM kunt bedienen en hoe u vanaf de ARM microcontroller tweets kunt versturen. Leer hoe u een CMUcam camera kunt aansturen en toepassen in uw applicaties, bijvoorbeeld als alarm. Leer hoe u met behulp van de gratis PC programmeertaal Visual Basic met uw ARM microcontroller kunt communiceren met gebruik van multi-threading. Voorbeelden van projecten in dit boek: internet-server, automatisch twitteren, digitaal naar analoog conversie, USB HID, automatisch metingen in een spreadsheet plaatsen, met een camera bewegingen waarnemen, seriële communicatie met een zelfgeschreven PC-programma, gebruik van een LCD en SPI en I²C communicatie.

Elektor Digital Android (NL) | E-book
Steeds vaker komen we op smartphones en tablet-computers het besturingssysteem Android tegen. Het aantal toepassingsprogramma's – de zogenaamde applicaties of kortweg apps - waarmee de apparaten individueel aan de voorkeuren en wensen van de gebruiker kunnen worden aangepast, neemt van dag tot dag toe. En de steeds betere technische uitvoering en uitrusting van de apparaten maken het nu mogelijk toepassingen te 'draaien' waarvoor een paar jaar geleden nog een desktop-PC of speciale hardware vereist was. Inmiddels kan elke smartphone de exacte (geografische) positie bepalen, video's opnemen – en nog veel meer. Maar bij het individualiseren van onze smartphone hoeven we ons niet te beperken tot kant-en-klare applicaties! Het is namelijk helemaal niet zo moeilijk om zelf Android-apparaten te programmeren en eigen apps te schrijven. Dit boek vormt een inleiding tot het programmeren van apps voor Android-apparaten. De werking van het Android-systeem wordt op begrijpelijke manier uitgelegd en we zien stap voor stap hoe applicaties kunnen worden geprogrammeerd. Aan de hand van een groot aantal voorbeelden worden allerlei toepassingsmogelijkheden getoond. Het scala loopt van eenvoudige rekenprogramma's via het uitlezen van sensoren en GPS-data tot het programmeren van applicaties voor internetcommunicatie. Naast het schrijven van applicaties in de programmeertaal Java wordt in dit boek ook besproken hoe apps met behulp van Javascript of PHP-scripts kunnen worden geprogrammeerd.
