ho provato e se inserisco quello che ha detto, torna il problema che gli asterischi non vengono digitati tranne il primo

Questo perché il reset lo avrai sicuramente messo dentro all'if in cui fai q++. La q la devi resettare quando esci, e se vuoi cancellare lo schermo, o comunque portare il cursore all'inizio, devi richiamare la funzione setCursor con lo 0 (zero) prima di rientrare nella digitazione della password. O, per chiarezza, settare q = 0 e chiamare di nuovo setCursor (q, 0) .

Però se fai delle modifiche, dovresti postarle, perché andare ad immaginazione non è sempre molto affidabile smiley-wink

Mi pare di capire che sei relativamente a digiuno di programmazione.

Anche se il linguaggio Arduino permette un approccio ai principianti, va ricordato che una base di programmazione (in C basta già) ci vuole per riuscire  fare un lavoro che non sia una "rattoppata" qua e là, che poi magari funziona ma fa acqua da un'altra parte. La mia non è un critica, ma un incitamento a fare le cose in modo ordinato e istruttivo. smiley-wink

Do you have a link to the vendor that shows a picture and possibly the pinouts. You said it is a serial lcd. What kind of serial ?

I don't know if it is helpful to raschemmel, but john have posted his configuration (with a classical Hitachi display) here: http://forum.arduino.cc/index.php?topic=243018.msg1742987#msg1742987

  I know what decibel are. I don't know what decibal are. Sorry

Why did you post the question if it is not related to the topic ?

Are you serious? but ok, it's because @notjohn13 used the term "decibal" more times and I wanted to kindly enlight him about his error, with a bit of sarcasm that you just killed.

BUT what's important is the message, one need to know and use the right terms. Now he knows. smiley-wink

I don't know what this means. (is this on the level or some kind of joke ?)

I don't know what decibal are, sorry.

Here let me help:

I know what decibel are. I don't know what decibal are. Sorry. smiley-mr-green

But, get back in topic now...  smiley-cool

I know the diodes are necessary if you actually  HAVE a power supply but as you pointed out I was refraining from just blurting out the answer but I couldn't hold it any longer. It was meant to be a fecetious remark implying that diodes are unnecessary as long as power is not connected. You know what I mean. I think the OP died.

Yes I get it. I thought that asking about the VS pin was sufficient... and instead. We'll see if that was the problem

What about the VS pin? He's feeling so alone there...
You need shunt diodes (shottky ones are even better).

You don't need the diodes because there is no motor power supply ....(look at the schematic).

VS is the motor power supply... smiley-wink
I was keeping myself from repeating that, to enforce amoultii to read better, as you want too
And diodes are needed, are not included in the IC, when motor will work

I am asking you (again and again) , do you or do you not know what is wrong with the schematic ?
It is a yes or no question. If you answer no , I will tell you. I am not going to tell you until you answer the above question, but I will tell you that anyone looking at your schematic would spot it immediately. I have already given you a clue. You ignored it. .

And could be even what I said earlier too... But mine was an explicit (and a bit poetic) answer, hope it is not ignored.

Da buon elettronico ingenuo mi chiedo, quando comincia ad aver senso usare ed imparare a lavorare su un RTOS?

Io con un PIC18 e qualche settimana di studio (ovviamente nel tempo che si trova), con MPLAB-X e XC8 posso scrivere in tutti i suoi 128KB di flash, anche se il codice compilato non verrà ottimizzato (XC8 è in free-mode), sfruttando un bootloader della Microchip. Un giorno mi dovrò prendere un picKit 3...  smiley-fat

Però il tutto non è arduinoso, ed è anche vero che sono un elettronico.. sarà quello smiley-grin

Magari uno più informatico può portare delle librerie ed adattarle all'ambiente. MPLAB-X è comunque supportatissimo da Microchip

Si certo lo so bene (non è neanche un problema per me...). Però mi riferivo al fatto che la ZERO porta molto più entusiasmo della DUE ma ha le stesse caratteristiche. E' dovuto al suo form factor? Solo per curiosità...
