The File System Component allows your embedded applications to create, save, read, and modify files in storage devices such as RAM, Flash, SD/SDHC/MMC memory cards, or USB memory devices. It is part of MDK-Professional.
File System Overview
The File System Component is structured as follows:
- Storage devices are referenced as drives which can be accessed by the user.
- Multiple instances of the same storage device can be implemented (for example you might want to have two SD cards attached to your system).
- The File System CORE supports thread-safe operation and uses an Embedded File System (for NOR and SPI Flashes) or a FAT File System which is available in two variants:
- The Long File Name variant supports up to 255 characters.
- The Short File Name variant is limited to 8.3 file name support.
- The Core allows simultaneous access to multiple storage devices (for example backing up data from internal flash to an external USB device).
- For accessing the drives appropriate drivers are in place to support
