FatFs module is an experimental project to implement FAT file system to small embdded systems. The FatFs module is written in compliance with ANSI C, therefore it is independent of hardware architecture. It can be implemented to most 8/16 small microcontrollers, such as PIC, AVR, H8, Z80 and etc..., without any changes. I created two modules in different configurations in consideration of various use. For read only applications, writing codes can also be eliminated to reduce the module size. To use the FatFs module, low level disk I/O functions for each media must be provided by user.
Features of FatFs Module
- Separated buffer for FAT and each file. Suitable for fast multiple file accsess.
- Low memory consumption (ex. avr-gcc)
- Module Size: 8282 bytes (R/W cfg.), 4482 bytes (R/O cfg.)
- Static Work Area: 2 bytes
- Dynamic Work Area: 544 + 540 * <files> bytes
- Supports FAT12, FAT16(+FAT64) and FAT32 (FAT64: FAT16 in 64KB/cluster)
- Supports 8.3 format file name and NT lower capital flags
- Supports two partitioning formats: FDISK (only 1st primariy partition) and SFD (only 512B/sector)
Features of Tiny-FatFs Module
- Only a common buffer for FAT and each file to reduce memory consumption.
- Low memory consumption (ex. avr-gcc), suitable for small memory system (1KB)
- Module Size: 6868 bytes (R/W cfg.), 3804 bytes (R/O cfg.)
- Static Work Area: 2 bytes
- Dynamic Work Area: 538 + 24 * <files> bytes
- Supports FAT12 and FAT16(+FAT64)
- Supports 8.3 format file name and NT lower capital flags
- Supports two partitioning formats: FDISK (only 1st primariy partition) and SFD (only 512B/sector)
