Hi,
I am using a Feather M0 with a datalogging firewing (RTC + SD card).
I have tried many sample sketches and many libraries, I have read various formums trying different solutions
but I was unable to write and read any data on the SD card.
I tried using the example sketches, first with
an arduino ONE
and later with an arduino DUE
and everything works perfectly.
At this point, I assume there is something wrong with the libraries.
any suggestions?
Thank you
Eric
