Library Example

This project consists of several blocks that demonstrate various aspects of usage of the Mmc_Fat16 library. These 

are:

- Creation of new file and writing down to it; 

- Opening existing file and re-writing it (writing from start-of-file); 

- Opening existing file and appending data to it (writing from end-of-file); 

- Opening a file and reading data from it (sending it to UART terminal); 

- Creating and modifying several files at once; 

- Reading file contents; 

- Deleting file(s); 

- Creating the swap file (see Help for details);
