General Description
The emFile component provides an interface to SD cards formatted with a FAT file system. The SD card specification includes multiple hardware interface options for communication with an SD card. This component uses the SPI interface method for communication. Up to four independent SPI interfaces can be used for communication with one SD card each. Both FAT12/16 and FAT32 file system formats are supported. This component provides the physical interface to the SD card and works with the emFile library licensed from SEGGER Microcontroller to provide a library of functions to manipulate a FAT file system.
