BTW, CB, thanks for your first feedback. I was pretty sure there wasn't any way of getting any meaningful code off the original Uno's. But you never know who's got a miracle solution in their back pocket.  smiley

Is that thing in the upper-right corner supposed to be so tarnished-looking?  Did it overheat?  Exposed to corrosive gas?

Actually, it's the only part I'll reuse. It's a Freescale MPX5700 pressure sensor. It's encapsulated in black plastic so it looks bad in the photo. (I should re-phrase... I'll test them and if they're OK, I'll reuse them.)

I wonder how the 7805 in the middle was damaged.  And aren't they supposed to each have two capacitors?

That would have been wise... The "damage" is intentional, though! As built, there was not quite enough room for the #4 bolt holding the Uno to the other side. Nothing a hacksaw wouldn't fix.

The whole project is a scrum meter for a rugby club. They want to see how various combinations of players put pressure on their opponents. They practice against padded scrum stands that have air cylinders supporting them. The MPX5700's measure the air pressure and I'll use the result to show the peak pressure, and graph the pressure over time on a Processing display.

However it turns out, I'm certain it'll be a thousand percent better than what they had.

You're not being overly helpful, CB. (But you're confirming what I suspected. smiley-razz)

The original physical construction was a nightmare. I suspect the code might be the same. Ah well, the end user is clear about what they want. I think I'll harvest the parts and rebuild.

BTW, here's what they got originally. It took me a day just to map out the relays...

They actually paid money for this!

Hello,

I've taken over a project without any documentation. I've got no access to the original code, and I'd like to avoid re-writing the whole thing. Is there a way to read the original sketch off an Uno?

I know I wouldn't get clean code, but it would be a starting point.


Thanks...

Hello OB,

I smiled when I saw that you were writing from Chile. My wife reads Isabell Allende and we both imagine the world she describes.

Are you asking about your profile on this forum? That can be changed via your User CP page. (That should be at http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?action=mycenter if you are logged in.)

On the left hand side, under "View" in the blue title bar, are three small tabs - "Messages", "Profile", and "Posts". Click on the Profile tab, then you can click on the "Edit Profile" link to change your profile.

I'm not sure how to get to the User CP page easily. I found it when I clicked on the message notification on my log-in page.

Good luck! I hope this helps.

Success! smiley-grin

I tried to force the communication by uploading a sketch, and the IDE hung up. The troubleshooting note for that problem ( http://arduino.cc/en/Guide/Troubleshooting#toc3 ) suggested killing LVPrcSrv.exe in the Windows Task Manager. Once that was gone, there was no more trouble.

I now have a blinking LED!

OK, still no connection with a different platform using W2K Pro.

Does anyone know if a Duemilanove core file it needed? I can see in the preferences.txt file that a specific board is named. Perhaps a new parameter set is needed for the Duemilanove.

This is getting frustrating...   >smiley-sad

OK, that's one thing I won't worry about. Thanks!

I'm still mystified by why the USB connection isn't working. Besides the serial error I mentioned, when I try to force a communication (e.g. burn a new bootloader) I get a "Can't find USB device at xxxx/xxxx."

It's possible that my Gateway laptop isn't working and playing well with others, so I'll try the whole thing on a different system when I get home.

I'm  first-time Arduino user so there's probably a simple solution. However, I can't see it yet.

I have the Arduino 12 IDE, and have loaded the latest USB drivers from FT. But the Duemilanove board still doesn't appear in the boards list on the tools menu. By default, the Diecimila is chosen.

Also, when the "Serial Monitor" is active, a constant stream of "ERROR:Pin 2-5" is received.

My O/S is XP Pro (Media Centre) with SP3.
Installed drivers are version 2.4.14.0, dated October 2008 from FTDI.
The IDE is Arduino 0012 alpha.

Any help would be appreciated, I'm stumped at this point. smiley-sad

My sensors are DS18S20+.  Not sure if different code is required for the +.  

On the DS1822 datasheet, the + version is a lead-free version. The coding should be no different.
