I'm using this same deek-robot logging shield and while the RTC works with the DS1307RTC library,
The SD card doesn't seem to work.
I used the cardinfo example and to my surprise, after a few runs it actually produced something
Initializing SD card...initialization failed. Things to check:
* is a card is inserted?
* Is your wiring correct?
* did you change the chipSelect pin to match your shield or module?

Card type: SD2
Volume type is FAT16
Volume size (bytes): 500948992
Volume size (Kbytes): 489208
Volume size (Mbytes): 477
Files found on the card (name, date and size in bytes):
My SD card is empty, so that output is correct.
I've set chipSelect to 10.
Why might the connection be fickle? Anyone else facing this issue?
