Buongiorno e buona domenica a tutti,
sto provando a far comunicare un arduino (master) con altri 3 arduino (slave) mediante seriale. In pratica il master fa da smistatore dei dati che riceve sulla seriale hw (Pin 0 e 1) e le trasmette ai tre slave tram...

the image link is broken somehow

I don't know how I missed that

Everyone is blind for his/her own code,
and the chance the error would occur is very small otherwise test runs would have shown it .

You were doing so good. Too bad you had to spoil it.

You're right, it is not the best, but do it before and it's quite simple.
On linux then I think we can run w...

The GS3 and the Nexus 7 can both recognize the Due with ADK 2012, I've tested with both. Are you running a custom ROM or kernel? Perhaps one that leaves out USB accessory...

I don't know for sure. I don't have a Due, so I suggest you email the makers (or suppliers) of the board.

The .h you posted here was just a copy of the cpp file it seems, post the actual .h as I can only make guesses now.

Re: Arbitrary precision (big number) library port for Arduino

Posted: 20 Jan 2013 01:04 AM PST

You might have to show your code. By default the big number library gives you no decimal places. Read this thread:

http://www.gammon.com.au/forum/?id=11519

Scroll down to where it talks about "setScale" which lets you set the number of decimal places.

Oh ok, I note that !
There is same part of the composant name erased on the 2 transistor (I think, but I'm not sure, that they are same)... I could be "S9...14" or "SW14" or "S9914". It realy difficult to read, even with wen.

Prossimi eventi: Workshop Base e Maker Faire – The European Edition

Posted: 19 Jan 2013 05:50 AM PST

Al periodico appuntamento con l'elettronica amatoriale presso Modena Fiere, che oggi e domani (19-20 Gennaio) ospita Expo Elettronica, i makers e gli hobbysti emiliano-romagnoli non possono rimanere delusi per il calibro degli ospiti in programma. Officine Arduino, assieme ai ragazzi del FabLab di Reggio Emilia, offrono un'occasione unica per confrontarsi con il mondo dei makers e con la prototipazione DIY, grazie a numerose varianti di stampanti 3D esposte e funzionanti, assieme alla possibilità di provare e "toccare con mano" alcune delle novità più interessanti del mondo Arduino, come l'Arduino DUE.

Lo stand del FabLab di Reggio Emilia.

Alcune delle novità più interessanti riguardano i prossimi eventi in programma, fra cui troviamo l'importante "Makre Faire – The European Edition", che verrà ospitata per la prima volta in Italia nei giorni 3-6 Ottobre 2013 a Roma e che vedrà coinvolta l'intera comunità di makers provenienti da tutta Europa. Fra gli eventi in programma vi saranno conferenze, workshop hands-on e numerosi speech, in aggiunta alla fiera "vera e propria" che si terrà nel week-end.

Per partecipare come espositori, a partire dal 18 Febbraio si aprirà una "Call for makers" alla quale chiunque sia interessato potrà inviare la propria candidatura e i propri progetti, che verranno accuratamente selezionati per costituire il programma delle numerose esposizioni previste. Stay tuned sull'home page della fiera per i prossimi aggiornamenti!

Costantino e Davide presentano la Maker Faire di Roma.

Fra gli imminenti eventi in calendario elenchiamo il prossimo Workshop Base di Arduino che si terrà i giorni 26-27 Gennaio a Reggio Emilia, presso il FabLab "Spazio Gerra". Le iscrizioni sono ancora aperte, ma i posti ancora disponibili sono limitati! Accorrete numerosi! :-)

Enabling F-bus communications with Arduino

Posted: 19 Jan 2013 12:00 AM PST

It's always nice to see how creative makers approach communication issues in DIY projects, and today we would like to highlight the approach followed by Alex, from InsideGadgets.

On his website, he provides a detailed tutorial on how to use an old Nokia 6110 (or any derivatives) to send SMS messages by exploiting the Nokia's F-bus, a simple bi-directional and full-duplex serial protocol.

After considerable reverse engineering work, made possible by useful online documentation, Alex finally managed to send a SMS from his Arduino board, connected to the phone, thanks to AVR libraries made available by AVRFreaks.

More information can be found on InsideGadget.
