Secure Digital (SD) is a flash memory memory card standard, based on the older
Multi Media Card (MMC) format. SD cards are currently available in sizes of up
to and including 2 GB, and are used in cell phones, mp3 players, digital cameras,
and PDAs.
mikroC provides a library for accessing data on SD Card via SPI communication.
Note: Secure Digital Library works only with PIC18 family.

Prototype
unsigned short Sd_Init(unsigned short *port, unsigned short pin);
Returns Returns 0 if SD card is present and successfully initialized, otherwise returns 1.
Description Initializes hardware SPI communication; parameters port and pin designate the CS line
used in the communication (parameter pin should be 0..7). The function returns 0 if SD
card is present and successfully initialized, otherwise returns 1. Sd_Init needs to be
called before using other functions of this library.
Example
error = Sd_Init(&PORTC, 2);
// Init with CS line at RC2
