Media Types
Hard Disk Drives
Sample Driver and reference designs have been created for interfacing an IDE HDD to a FAT file system. Also provided in the file system are caching options which are essential when using a HDD. The caching mechanisms combined with the efficiency of SFATFS and its mainly zero-copy reads and writes gives the best possible performance when implementing a HDD on an embedded system.
MultiMedia Card and
Secure Digital Cards
This is probably the simplest method to add a DOS compatible file media to your embedded device. We provide a range of drivers for interfacing to SD and MMC cards including standard SPI implemented in either hardware or software. We provide hardware design information for implementing this.
Compact Flash Cards
Compact Flash cards require a more complex communication with a PC compatible media but offers performance advantages because of the wider data bus thus generally a higher throughput is achieved and in many cases a reduced CPU load. We also provide hardware design information and CPLD logic where appropriate.
RAM Drive
A RAM drive is provided as standard and is particularly useful in getting a system up and running without any hardware dependencies.
