mikoPascal PRO for dsPIC30/33 and PIC24

Library Example
This project consists of several blocks that demonstrate various aspects of usage of the Cf_Fat16 library. These are:
- Creation of new le and writing down to it;
- Opening existing le and re-writing it (writing from start-of-le);
- Opening existing le and appending data to it (writing from end-of-le);
- Opening a le and reading data from it (sending it to USART terminal);
- Creating and modifying several les at once;
- Reading le contents;
- Deleting le(s);
- Creating the swap le (see Help for details);
