It doesn't do what you need, without modification, right? And an Atmega328 chip on a small board with a SD card attached in some way, could also do that.

I think your questions could usefully be directed at Sparkfun. The links they give are broken. So the claim to be open source is not, right now, true.

If you could get the source, and work out how to reprogram the chip, certainly it would be a nice compact solution.

I left a couple of message in OpenLog page, I'll try by email too.

Links worked yestewrday  for me... but the "source" is a .cpp.hex file (double extension?!?) Today they all result in 404-error.

Indeed.  :)


But.... look at what I found!  :)

Found original OpenLog source:

https://github.com/magnuskarlsson/SDLogger/blob/27f5458e9e3796532fcbbf82ade138c84d72ca4a/OpenLog_v2/OpenLog_v2.pde

Can opensource be copirighted?!?

I didn't notice this line in OpenLog Sparkfun page:
Reprogrammable ATmega328 using the Arduino IDE

So it's ACTUALLY an Arduino glued to an SD card reader. :-)

Authors initially derive a right to grant a license to their work based on the legal theory that upon creation of a work the author owns the copyright in that work. What the author/licensor is granting when they grant a license to copy, modify and redistribute their work is the right to use the author's copyrights. The author still retains ownership of those copyrights, the licensee simply is allowed to use those rights, as granted in the license, so long as they maintain the obligations of the license.


My understanding is that "as owner of the copyright, I give permission for you to use my software". This permission usually includes a clause which stops the recipient from removing that permission for derived works.
