FreeRTOS+FAT: DOS Compatible Embedded FAT File System

FreeRTOS+FAT is an open source, thread aware and scalable FAT12/FAT16/FAT32 DOS /Windows compatible embedded FAT file system which was recently acquired by Real Time Engineers ltd. for use with and without FreeRTOS.

FreeRTOS+FAT is already used in commercial products, and is the file system used in the FTP and HTTP server examples that are documented on the FreeRTOS+TCP pages.

The standard C library style API includes a thread local errno value, and the lower level native API provides a rich set of detailed error codes.

For more details, please visit FreeRTOS+FAT page.
