Secure Digital Library
mikroC - C Compiler for Microchip PIC microcontrollers
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.
Library Routines
Sd_Init
Sd_Read_Sector
Sd_Write_Sector
Sd_Read_Cid
Sd_Read_Csd
Sd_Init
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 |
