View Full Version : MMC or SD cards

Has any one interfaced MMC or SD cards to AVR?
I am building a data logger for which I want to interface 64K SRAM to mega8515.
The data is first recorded on SRAM as it comes and when it is abt to become full, the data is written to MMC card.
I have some idea abt interfacing SRAM but never worked with MMCs before.
WinAVR has library functions for accessing MMCs, but I have never used WinAVR can anyone tell me how to use it? some c code examples would be very helpful.
