MMC/SD card reader
An AVR-based small test application which implements read and write support for MMC, SD and SDHC cards.
This project includes:
* low-level MMC, SD and SDHC read/write routines
* partition table support
* a simple FAT16/FAT32 read/write implementation
The software is written in pure standard ANSI-C. It implements a simple command prompt which is accessible via the UART at 9600 Baud. With commands similiar to the Unix shell you can browse different directories, read and write files, create new ones and delete them again. Not all commands are available in all software configurations.
