This code provides a generic set of routines for accessing an SD card from an AVR device. The routines are target-independent; they do not know about or depend on any hardware characteristics of the target design. All of the target-dependent hardware accesses are done in the host code (your program). Functions needed by the library code are made available through a special routine called sd. here is the code for initialization of SD card: //sdcard.h #ifndef SDCARD_H_ #define SDCARD_H_ #define GO_IDLE_STATE 0 #define SEND_OP_COND 1 #define SEND_IF_COND 8 #define SEND_CSD 9 #define STOP_TRANSMISSION 12 #define SEND_STATUS 13 #define SET_BLOCK_LEN 16 #define READ_SINGLE_BLOCK 17 #define READ_MULTIPLE_BLOCKS 18 #define WRITE_SINGLE_BLOCK 24 #define WRITE_MULTIPLE_BLOCKS 25 #define. .

As far as I know there is a problem with SD card writing - you have to write whole 512 byte blocks, you cannot write single bytes as EEPROMs usually enable. So if you want to use the whole capacity of the card you need to have a buffer 512 bytes large. So I expected 600 bytes will be more then enough to implement the SD card of which I can use the 512 bytes buffer to store collected data. Use a SD/MMC card ,much easier than compactflash Just set the AVR for SPI , and connect the SD/MMC via a cpl of voltagedividers. See www.microsyl.com (LCD sign) Carsten Reply Start a New Thread.
