Filesystem

We use FatFS as the file system handler. Have a look at the API and examples on the FatFS site fore usage information.

The FatFS module will be initialized by the micro-SD deck driver when the deck is detected. After that the API calls can be used such as f_mount, f_open, f_read, f_close etc.
