µC/FS
µC/FS is a compact, reliable, high-performance file system. It offers full-featured file and directory access with flexible device and volume management including support for partitions.

Source Code: µC/FS is provided in ANSI-C source to licensees. The source code is written to an exacting coding standard that emphasizes cleanness and readability. Moreover, extensive comments pepper the code to elucidate its logic and describe global variables and functions. Where appropriate, the code directly references standards and supporting documents.

Device Drivers: Device drivers are available for most common media including SD/MMC cards, NAND flash, NOR flash. Each of these is written with a clear, layered structure so that it can easily be ported to your hardware. The device driver structure is simple—basically just initialization, read and write functions—so that µC/FS can easily be ported to a new medium.

Devices and Volumes: Multiple media can be accessed simultaneously, including multiple instances of the same type of medium (since all drivers are re-entrant). DOS partitions are supported, so more than one volume can be located on a device. In addition, the logical device driver allows a single volume to span several (typically identical) devices, such as a bank of flash chips.

FAT: All standard FAT variants and features are supported including FAT12/FAT16/FAT32 and long file names, which encompasses Unicode file names. Files can be up to 4-GB and volumes up to 8-TB (the standard maximum). An optional journaling module provides total power fail-safety to the FAT system driver.

Application Programming Interface (API): µC/FS provides two APIs for file and directory access. A proprietary API with parallel argument placement and meaningful return error codes is provided, with functions like FSFile_Wr(), FSFile_Rd() and FSFile_PosSet(). Alternatively, a standard POSIX-like API is provided, including functions like fs_fwrite(), fs_fread() and fs_fsetpos
