Hi,
I wish to use this library for my CT-ARM project too. But unfortunately, it has compilation error too. The sketch I am using is dataLogger, can be found in the 'examples' folder.
This library is better than SD.h in data logging, I am sure by making SdFat.h available for CT-ARM will be beneficial to others too
Looking forward. Thanks.
