Part Number: Memory Disk Drive File System for PIC18 PIC24 dsPIC PIC32

MEMORY DISK DRIVE FILE SYSTEM FOR PIC18 PIC24 DSPIC PIC32

  • Based on ISO/IEC 9293 specifications
  • Provides a method of interfacing to files and directories on FAT12, FAT16 and FAT32 file systems
  • FAT16 and FAT32 allow access to up to 2 gigabytes and 2 terabytes of memory, respectively
    • FAT 16 standard used for most SecureDigital (SD) cards, CompactFlash® (CF) cards and MMCs MultiMedia Cards sized below 2 gigabytes (GBs)
    • FAT32 standard can be used to address memory sized between 2 gigabytes and 2 terabytes
  • Most popular file system with SD cards, CF cards and USB thumb drives
  • Hardware evaluation supported by PICtail Plus® SD & MMC Daughter Card (AC164122) and USB PICtail Plus Daughter Card (AC164131)
  • MDD file system library supports the 8-bit PIC18 devices as well as the 16-bit PIC24F, PIC24H, dsPIC30 and dsPIC33 devices and 32-bit PIC32 devices

Overview

Microchip’s Memory Disk Drive (MDD) file system interface library brings the ability to transfer and share portable memory devices between and embedded system and a personal computer. The MDD library provides a method to read and/or write to these storage devices through a microcontroller. The data of these storage devices can be read by a PC, and the data written by a PC can be read by a microcontroller. Most operating systems (i.e., Windows® XP) support the FAT16 and FAT32 file systems.
