mmc + avr

Ulrich Radig source is just readonly fromm mmc/sd as far as I know.

What compiler are you using ?

speaking frankly , i did not reused this code, but suppose that it works .

Having look to mmc.h and mmc.c i noticed following functions already implemented in this projects :
(**broken link removed**)

inline U08 mmc_read_byte(void);
inline void mmc_write_byte(U08);
extern void mmc_read_block(U08 *,U08 *,U16);
extern U08 mmc_init(void);
extern U08 mmc_read_sector (U32,U08 *);
extern U08 mmc_write_sector (U32,U08 *);
extern U08 mmc_write_command (U08 *);
extern U08 mmc_read_csd (U08 *);
extern U08 mmc_read_cid (U08 *);
