The PetitFS library contains one example and it is how to read. I have looked extensively through the internet but cannot seem to find anything. Just looking for someone with experience with the library.Thanks
My earlier comment was a hint that you needed to post a link to the library. It can't be too hard to write to a file on the SC card, IF the library supports that. It is possible that the way the library is able to be so small is that it doesn't support writing, but that seems unlikely.
