Which one is the working Due version?

another thing... my board has the IC10 between header but has other things like the other version... it seems to be a mix of the two version in the photo :open_mouth:

i mean...

franceslup:
i mean...

i have the same version.
My store was: https://shop.boxtec.ch/
Shipping was on 24. Oct

the same of the mine?

yes

instead of this... my DUE work's perfectly :smiley:

Looks for me like an first release without the RTC-crystal because the Aref labeling is missing too.

and why they sold out this board??? We bought all together at the same prize, the SAME board... but they are different...

The differences are so small that it doesn't matter.

I think a missing crystal is a huge difference. Especially for people who wanted to use the SAMs RTC.

Yes...!

Yes, well if they added the crystal I'd have to agree that it makes a difference, but they have removed it so there will not be any support for using it. Has someone actually gotten a board with the crystal? If then it's just a very small number of boards that has it.

(Don't get me wrong, I'd like the crystal too. But I'm sure they had their reasons for removing it.)

Hopefully not just saving 20 Cents. -.-

and why there are different version of the board if is still sold out and we bought the same board at the same moment :S ?

That's a good question... My Due's already arrived and I'll collect it tommorow. Now I'm really curious to see which of the versions it is...

let us know... :smiley:

All right, I'll let you know :slight_smile: (I don't grant you it will be tommorow though...)

Markus_L811:
It's an question too, where you bye it, from the Arduino Store or somewhere else, maybe there is an first pullout with different design or the first pullout to the other reseller is different to the first pullout buyed from the Arduino Store.

I bought it from this store http://www.ptrobotics.com . It's one of the stores in Arduino's Distributors page Distributors — Arduino Official Store .
From what I know I believe 5 Dues were dispatched to this store right after it went on sale. They arrived there sometime between thursday and friday on the release week.

The RTC can be used just without the cystal you can choose in the register to use external or internal clock

Good to know.

Thanks, man.

No problem.

I tried this but unfortunately it looks like the internal RC oscillator isn't nearly accurate enough. Mine is about 10% slow :frowning:

void setup()
{
  Serial.begin(9600);
}

union urtc { 
  struct {
    byte secs,mins,hrs,pad;
  } time;
  long dat;
} rtc;

byte BCD2bin(byte b){return (b&15)+((b>>4)*10);}

void loop()
{
  rtc.dat=RTC->RTC_TIMR;
  
  Serial.print("At the third stroke, it will be ");
  Serial.print(BCD2bin(rtc.time.hrs));
  Serial.print(":");
  Serial.print(BCD2bin(rtc.time.mins));
  Serial.print(":");
  Serial.print(BCD2bin(rtc.time.secs));
  Serial.println(" imprecisely.");
}

My Due (bought from arduino.cc store within minutes of the store being updated after the announcement) has IC10 between the headers, no JTAG header, and a missing RTC crystal. It arrived on Monday 29 Oct, but I just saw it today as I was away all week.

I just received two Due's in today. They were ordered from the Arduino Store the same day it was listed online. They both look just like the "current one" in the first photo.
