A simple SPI SD card interface for the Stellaris Launchpad [rewrite in progress]

stellaris-sd v0.1

A simple SPI SD card interface for the Stellaris Launchpad, written in C with TI's driverlib.

info

This provides a basic read/write interface to an SD card attached to (currently) the SSI0 peripheral. Pins used are detailed in mmc.h, and #defines can be changed from there - this is not pervasive, and there remain a few hardcoded constant. This will change.

This library uses TI's proprietarily licensed uartstdio software, and as of such I cannot include it in this "virally licensed" distribution. By default any code that uses it is #define'd out, but this can be changed. Simply uncomment __UART_DEBUG, and place uartstdio.c and uartstdio.h in the source directory.

A Makefile will be added as soon as I clean it up a bit.

Eventually this library should provide all the necessary functionality to run Chan's FAT-fs filesystem.

Otherwise, the code is commented decently, and everything should work with non-SDHC cards. As always, ymmv.
