8 | ff.c FatFs module.\r | |
9 | diskio.h Common include file for FatFs and disk I/O module.\r | |
10 | diskio.c An example of glue function to attach existing disk I/O module to FatFs.\r | |
11 | integer.h Integer type definitions for FatFs.\r | |
12 | option Optional external functions.\r | |
13 | \r | |
14 | Low level disk I/O module is not included in this archive because the FatFs\r | |
15 | module is only a generic file system layer and not depend on any specific\r | |
16 | storage device. You have to provide a low level disk I/O module that written\r | |
17 | to control your storage device.\r | |
