Implementing file I/O functions using Microchip's memory disk drive file system library

Posted: 02 Oct 2007 ?? ?Print Version ?Bookmark and Share

Keywords:memory disk drive? SD card? MCU?

This application note covers the usage of file I/O functions using Microchip's memory disk drive file system library. Microchip's memory disk drive file system is:

  • Based on ISO/IEC 9293 specifications

  • Known as the FAT16 file system, used on earlier DOS operating systems by Microsoft Corp.

  • Most popular file system with SD card, CF card and USB thumb drive

    Most SD cards and MMCs, particularly those sized below 2Gbyte, use this standard. This application note presents a method to read and/or write to these storage devices through a microcontroller. This data can be read by a PC and data written by a PC can be read by a MCU. Most operating systems (i.e., Windows XP) support this file system.
