Mmc_Fat_InitmikroC - C Compiler for Microchip PIC microcontrollers
Prototype | unsigned short Mmc_Fat_Init(unsigned short *port, unsigned short |
| pin); |
|
|
Returns | Returns 0 if MMC card is present and successfully initialized, otherwise returns 1. |
|
|
Description | Initializes hardware SPI communication; designated CS line for communication is RC2. |
| The function returns 0 if MMC card is present and successfully initialized, otherwise |
| returns 1. |
| This function needs to be called before using other functions of MMC FAT library. |
|
|
Example | // Loop until MMC FAT is initialized at RC2 |
| while (Mmc_Fat_Init(&PORTC, 2)) ; |
|
|
Prototype | void Mmc_Fat_Assign(char *filename); |
Description This routine designates (“assigns”) the file we’ll be working with. Function looks for the file specified by the filename in the root directory. If the file is found, routine will initialize it by getting its start sector, size, etc. If the file is not found, an empty file will be created with the given name. The filename must be 8 + 3 characters in uppercase.
Requires | Library needs to be initialized; see Mmc_Fat_Init. | |
|
|
|
Example | // | Assign the file "EXAMPLE1.TXT" in the root directory of MMC. |
| // | If the file is not found, routine will create one. |
| Mmc_Fat_Assign("EXAMPLE1TXT"); | |
