Arduino Due [A000062]

Insgesamt ist es ein solides Arduino Board mit vielen Funktionen fürs schnelle Protoyping. Beispielsweise die beiden DAC Kanäle sind sehr vom Vorteil, wenn man analoge Schaltungen ansteuern möchte. Auch Funktionen, wie natives High-Speed USB, eine (relativ) hohe Taktfrequenz, mehrere Serielle Schnittstellen, usw. Somit ist es ein ideales Board für jeden Maker, Hobbyist, etc. im Bereich des Prototypenbaus. Jedoch ist der Preis sehr happig mit um die 42 Euro. Dafür gibt es schon von anderen Herstellern bessere Boards für kleineres Geld, welche dann bestimmte Funktionen des Due drauf haben. Der Due hat sie aber alle. Somit kann dieses Board ein absoluter Schatz im Prototypenbau sein, würde aber von einer Serienfertigung mit diesem Board abraten, da der Preis ja wie beschrieben doch etwas höher liegt...

The Due from arduino.cc (the original Arduino group) has been discontinued, but Arduino.org (you can read up on the issues between the .cc and .org groups) made this Due board. That would be the only difference. The number of pins and amount of memory make this board especially useful. And as an added plus, it works with the Arduino Yun Shield (see the arduino.cc website) which allows the Due to communicate via Bridge.h to the Yun (which runs Linux and includes wifi and ethernet connectivity). Just add this to your Due sketch: #include <BridgeClient.h> // Arduino Due to Yun Shield communication BridgeClient client; You can also access Linux processes by including: #include <Process.h> which, for example, will allow the Due to get the current system date and time from the Yun. Over-the-air programming is the nicest feature of the Due-Yun combination which allows programs to be upload to the Due when it is connected to wifi. To enable this functionality, you first upload a sketch to the Due via USB with the setup() containing the line 'checkForRemoteSketchUpdate()' as shown below: void setup() { checkForRemoteSketchUpdate(); // use for Due when programming over Yun Shield } void loop() { // put your main code here, to run repeatedly: } After that, sketches can be uploaded by just including 'checkForRemoteSketchUpdate();' as the first line in the setup. From [...] DUE boards special note This board can be programmed remotely, but the way it interacts with the Yún shield requires a specific procedure that it is initialized by the checkForRemoteSketchUpdate() function. As suggested by the name this instruction is responsible to check if there is a new sketch to upload on the board. This is required only on the Due because you need to erase the flash before uploading a new sketch. The same action is performed automatically when you upload a sketch using any of the USB ports. Check the example called RemoteDueBlink includedin the Bridge library (Example -> Bridge -> RemoteDueBlink), which introduces you on how to use the checkForRemoteSketchUpdate() function. You must first load such a sketch via USB and also remember that any remotely loaded sketch must have that instruction to maintain the remote upload functionality. In order to enable the remote upload feature you need to install the SAM core version 1.6.8 or greater. To ensure that remote upload works you need to power the DUE from the barrel jack or using the Native USB port.

D'abord vous devrez installer l'Arduino IDE et télécharger le paquet pour supporter les contrôleur en SAM (donc celui-ci inclus). Il suffit ensuite de brancher l'arduino en micro/mini-usb et choisir l'arduino dans l'IDE (native ou programming port et le port COM). Fonctionne très bien, pléthore de pins comparés au raspberry pi. Il y a beaucoup plus de ressources que sur les modèles précédents même si cela ne reste pas glorieux (n'imaginez pas faire tourner linux ou autre dessus, pour cela il faut voir le yùn). Attention les pins ne supporteront pas plus de 3.3V, auquel cas vous risqueriez de détruire un pin voir le processeur entier.

Preso “per sbaglio” (non avevo ancora capito la differenza tra il Due e il Mega) senza neppure conoscerne pregi, difetti, caratteristiche, funzioni… Arduino Due non è esattamente “compatibile” con le librerie utilizzate da Uno (Nano, Mega…) e in rete non è semplice trovare “la pappa pronta” (sempre non si chieda a ChatGPT :P ) e il fatto che i suoi pin supportino solo tensioni inferiori o uguali a 3,3volt (a differenza degli altri Arduino che accettano fino si 5volt) lo rende “meno compatibile” alle “periferiche” (shield) che si possono collegare. Prodotto ottimo per chi ha voglia di apprendere nuove cose e si accinga alla prototipazione di un suo progetto elettronico, meccanico, motive, di domotica… (siamo circondati ed utilizziamo ogni giorno un prodotto che contiene una scheda simil Arduino). Le potenzialità sono davvero incredibili soprattutto perché, essendo open source, crescono assieme alle persone che utilizzano questo sistema. Ogni scheda Arduino ha i suoi pregi e i suoi difetti ed è più o meno indicata per le proprie finalità (esattamente come accade per i computer). Contentissimo del mio acquisto arrivato nei tempi prestabiliti ed abbandonato sul vialetto di casa da un corriere troppo sbrigativo (poteva almeno suonare il campanello)

I needed a Due very specifically for a project. I didn't want a clone, or something "close". This was a very good price, and bonus - came with a clear 'case back' that protects the back of the board when you use it without the rest of a case getting in the way. Perfect for shield-based projects.
