Together with Rodrigo Castro an Arduino 1.0 update was made for - http://www.arduino.cc/playground/Main/DS1307OfTheLogshieldByMeansOfNTP -

The code should work under 0.22, 0,23 and 1.0

As always comments and remarks are welcome, in this thread.

Thanks for this.

Should the code be updated to prefer DHCP if the Arduino board supports it?

Also,

07/01/2011
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1291637975#10
shows DST function, to be integrated.

Was this integrated into the 04/01/2012 version? I'm unsure how/if I would need to handle DST for my location/project.

THANKS

no, not integrated, but you are free too.

I prefer to do my logging without DST to prevent gaps/doubles in my data set

I think there is a typo in the example sketch on the playground.

Code:

#if ARDUINO >= 100
#include <EthernetUdp.h>        // New from IDE 1.0
#else
#include <UDP.h>
#endif

UDP.h should be Udp.h
At least on my system:
sketch_apr26a.cpp:31:17: error: UDP.h: No such file or directory
I'm still using version 0023, my gentoo installation and 1.0 don't play nice. I should do something about that and switch to 1.0  

Oh, and thanks for the sketch and libraries.

updated the example, thanks for the feedback

I am using Arduino IDE 1.0.1 and I can't get UDP , I Know all about IP addressing and gateway etc...
My MAC Address don't even show up on router list....
No Compile errors....

Can this work with on v 1.0.1 ?

[Reply #6 on:]

I downloaded Arduino IDE V 1.0 and it worked!
The IDE V 1.0.1 Don't Work..... Byte Command Word ? Something changed in the compiler....

@shane
have you checked the release notes of 1.0.1?

As I have limited time now (other prio's) I cannot dive into this and redesign it to support new version. If you have patches please share them here.

Thanks,
Rob

Having originally failed continually with "No UDP available ...", I managed to get UDP working by first reading packet size by using parsePacket, and then modifying the Udp.read to use that packet size

Code:

int packetSize = Udp.parsePacket(); //<<<<<<<<<<<<NEW LINE HERE
// send an NTP packet to a time server
sendNTPpacket(timeServer);

...
Udp.read(pb, packetSize);      // New from IDE 1.0 <<<<<<<<<<<<<MODIFIED LINE

And then, if you aren't in Chile, remember to make your own adjustment to UTC in the line which reads

Code:

t4 -= (3 * 3600L);

(the notes say this is a 4 hour adjustment, but clearly it is 3 hours)

Thanks John for this improvement!

can you post your complete modified version, then I will update the playground code.

Thanks again,
