Hi,
I just did a quick search in the forum but could not see any information on the potential software/firmware differences between an Arduino Uno SMD and the newer R3.
I have installed the Camera + SD card sketch from the Radio Shack site - http://www.radioshack.com/graphics/uc/r ... 760248.zip
This uses serial communication for the camera and SDI to the Seeed Studio SD Shield v3.1 - http://www.seeedstudio.com/wiki/SD_Card_Shield_V3.0
I set the device select pin to be '10' and upload the sketch to the Arduino Uno SMD - this works just fine, I can see the serial communication and the SD card gets a fresh JPG image every time the motion detect routine fires.
I upload the same sketch to the UNO R3 and nothing happens, no serial comms, no JPG image.
Is there a resource anywhere that outlines potential differences between these two devices?
Was anything changed in the R3 to affect how SDI or serial comms works?

Re: SD + Camera sketch working on Uno SMD, not on R3
I am not aware of any backward compatibility issues with the UNO R3. The R3 has 2 extra header pins on each side, but these are duplicates of existing UNO pins.
The R3 uses a 16U2 for USB/Serial communication instead of the 8U2 used in earlier versions. But I have not experienced or heard of any incompatibilities in operation.

Thanks for the confirmation, I will do some more digging into what could be going wrong and post back if I find something useful.
I've been using Arduino's for years, and never seen this before.
It could, of course, be a faulty 'duino.
