Go ahead and put the information here if you could.

You can use code tags when you reply.  Just click the # button when you make a reply and put the code or lines you changed in between the tags.

Once someone can confirm it has fixed it, mantoui can possibly update his files with the changes.

2  Products / Arduino Due / SHA1/SHA256 library for DUE? on: June 12, 2013, 09:24:55 pm

I have tried to run the Cryptosuite for the Arduino DUE available from here:

Unfortunately, the library only compiles on UNO and Leonardo devices because it uses the PROGMEM.

Has anybody gotten this library to work?  I'm interested in using the library in an Arduino DUE project that connects to a MySQL database directly with Chucks code here:

Does anyone have this working or be willing to help me port this library to DUE?

Is there a guide out there on how to un-PROGMEM a project so it will run on DUE?  smiley
I understand it will take up more memory then on other platforms because we can't store a couple of the large char array values in EEPROM but I'm willing to try if anyone can help me.

Looks like a really nice library.  Also, I think you have done a great job on the documentation and examples.  I have a project in mind it would be perfect for.

Are there any limitation on the maximum amount of threads?

Thanks for the contribution.
4  Products / Arduino Due / Re: Taiji-Uino Due RTC broken? on: April 24, 2013, 06:05:13 pm
Yup, looks like the Taiji-uino clone skipped a component.  There's no crystal.

If you un-comment the line:
RTC_clock rtc_clock(RC); will work on the Taiji-uino.  Thanks for clearing that up Markus and btw, your work around here is much appreciated.  Electric house can't exactly skimp on an RTC because it's baked into the silicon!

5  Products / Arduino Due / Taiji-Uino Due RTC broken? Nope, just missing a crystal. on: April 23, 2013, 03:51:02 pm

I wanted to use Markus's really nice RTC library on my Taiji-Uino Due but the code is not working. 

Here is his library:

If I run the example "Due_RTC_Simple_Sample", I do not get anything back on the serial monitor.  However, If I plug in my Arduino brand Arduino Due, I get results like I expect from the example sketch.

I have a second Taiji-Uino and that one is having the same problem...  Maybe I got a couple of them from a bad batch?

Can someone else with a Taiji-uino Due verify what I am seeing?

Thanks for sharing your project code!  Looks to be a really nice library you got there.  What kind of applications are you using it for with sub 1ms speed?  I can imagine a few but just curious of how your using the library and what application, knowing more could get more people on board and using it and adopted further.

Thanks for the great documentation too, so many projects are just a pile of code with no instructions on how to use it, it's great that you took the time to really polish up the documentation!

I couldn't find an Eagle library for the DM9161 Ethernet PHY chip so I made my own library.  Hopefully this is a start to a PCB.

This is actually my second Eagle library I have ever created so hopefully I didn't screw it up.

Thanks for the update Palliser, I should get some of the DM9161 chips on Monday and hopefully have a home brew version of the AS-DM9161 within a week or two.  Just in time to run your API against it!

I'll post up my Eagle files here when I got them ready.
9  Products / Arduino Due / Re: Connecting an Ethernet PHY to Arduino Due on: February 06, 2013, 12:33:01 pm
Looks like I found a header that will work for the TaijiDUE, It's 1.27 mm pitch dual row:

I've been getting a little better at using Eagle recently and looking at the schematic for the AS-DM9161 it looks fairly simple and possible to build at home:

I think I might be able to recreate this in Eagle as long as the schematic is correct.  I may need you to verify Palliser.  It's basically a Ethernet magjack, the DM9161, some resistors, capacitors, an oscillator and a header for breadboard.  Anyone interested?

10  Products / Arduino Due / Re: Connecting an Ethernet PHY to Arduino Due on: February 05, 2013, 10:39:15 pm
I received a couple of the TAIJI-UINO Due models from Elechouse.  The build quality is pretty good overall but one of them had a bit of metal in the USB mini-b connector that I had to bend out with a precision screwdriver.

Let me know if you want any up close pictures of it, I'll be happy to post them up.

I don't have any pins small enough to solder into the holes for the ethernet terminal area so I'll have to figure out what size they are and order some.  They look to be the same size as the small pins next to the Due 4 pin debug post.  Anybody know what size those are?

I'm still waiting on some of the Davicom phy chips to arrive along with some 50 mhz oscillators and some extra magjacks.  I figure I'll just re-create the AS-DM9161 schematic on a breadboard since ordering them from the Russian site wasn't very apparent.
11  Products / Arduino Due / Re: RTClib DS1307 with Arduino on: February 05, 2013, 10:28:25 pm
I was able to use the DS1307 with the RTClib from jeelabs, the examples work no problem once you get the DS1307 hooked up correctly - I don't have the breakout board from Adafruit, I just have the chip and a 32 mhz oscillator and a breadboard.  Works like a champ.

Here is the link to the RTClib I used on the Due.
12  Products / Arduino Due / Re: DUE ethernet performance on W5200 with SPI and SPI+DMA on: February 03, 2013, 09:05:57 pm

Thanks for the heads up, I tried the code though and it has the same problem as the other code I have tried. 

I guess at this point I'll attempt to reach out to Jinbuhm Kim and see if he has an idea what is going on.  It seems like too many requests to the RX buffer of the W5200 is triggering a condition where it doesn't respond to any more requests.  Since all the TCP/IP stack is contained within the W5200 chip it doesn't seem like this is an Arduino problem per se and may be a bug in the W5200 itself.

WIORE, have you been able to try any of the code? Are you still having the same problem?  If so, we have a documented issue we can go to WIZnet and see if there is a fix or at least get them to acknowledge the problem.
13  Products / Arduino Due / Re: DUE ethernet performance on W5200 with SPI and SPI+DMA on: February 03, 2013, 11:03:42 am

Thanks for the link to your library.

I was able to download it and run the WebServer sketch and just like you said in another thread I was able to run 8 firefox tabs each pulling data every few seconds!  Awesome! I was never able to do that with the official Ethernet shield so that is a positive step forward.

I was still having the same problem though where if I perform too many requests (pressing F5 in browser) to the W5200 chip it will basically lock up and stop responding to any GET requests from the browser and also stop responding to ICMP (PING).  Even an hour later it still does not come out of the stuck condition.

Are you having the same problem?

I'm starting to think there may be a bug in the chip because the exact same thing happens when I have the W5200 chip hooked up to the Arduino UNO running Arduino IDE Version 1.0 with the official (from WIZnet) libraries:
If you go to the link above and click on the "Download" section there are a couple zip files containing WIZnet's updated W5100.h and W5100.cpp files so you can run the W5200 chip.  The code from WIZnet has the same problem locking up when too many requests come in.  Maybe the request Internal 32 Kbytes tx/rx buffer is getting filled and causing it to crash?

14  Products / Arduino Due / Re: Wireless SD Shield usable? on: January 29, 2013, 04:54:53 pm
They stack on top of each other like this image:

Once you have them connected together open up the Arduino IDE and go to the Wifi examples:
File > Examples > WiFi > ConnectWithWPA

There are a ton of examples in the File > Examples >WiFi section.
15  Products / Arduino Due / Re: Due EEPROM alternative? SD? on: January 25, 2013, 06:10:35 pm
Why not use an external EEPROM?

They are cheap and almost never wear out compared to the SD card and you can pick up something like the 24LC256 for very cheap.
