Multi Media Card Library
mikroC provides a library for accessing data on Multi Media Card via SPI communication.
Notes:
-Library works with PIC18 family only;
-Library functions create and read files from the root directory only;
-Library functions populate both FAT1 and FAT2 tables when writing to files, but the file data is being read from the FAT1 table only; i.e. there is no recovery if T1 table is corrupted.

Returns | Returns 0 if MMC card is present and successfully initialized, otherwise returns 1. |
Description Initializes MMC through hardware SPI communication, with chip select pin being given by the parameters port and pin; communication port and pins are designated by the hardware SPI settings for the respective MCU. Function returns 1 if MMC card is present and successfully initialized, otherwise returns 0.
