hello guys !
i need to interface an SD/MMC card with PIC 18F4520 , just to read/write a text file .
well , i wrote a simple code on Mikroc as a start , but i faced a problem once i use "Mmc_fat_init() " .
here is the code :
this code is working correctly on proteus , but once i uncomment the line " //MMc_Fat_init() ; " then the initialization fails in the proteus .
anyone can give a help
thanks

error = MMC_Init();
while(error == 1)
{
error = MMC_Init();
}
//MMc_Fat_Init() ;
