Good SPI sample with MMC or SD card

Portable FAT Library for MCU Applications
Ivan Sham, William Hue & Pete Rizun
The DOS FAT file system is the industry standard format for flash 
memory cards. You can use a microcontroller to read and write files on 
an SD/MMC flash memory card with the FAT system. Read on to learn how 
to build a portable FAT library for MCU applications. p.18

Keywords: DOS FAT, SD/MMC, memory card, flash, file system, MSP430
