Library Example
The following program tests MMC FAT routines. It creates 5 different files in the root of MMC
card, and fills them with some data. You can check the file dates which should be different.
char FAT_ERROR[20] = "FAT16 not found";
char file_contents[50] = "XX MMC/SD FAT16 library by Anton Rieckert";
char filename[14] = "MIKRO00xTXT"; // File names
unsigned short tmp, character, loop;
long i, size;
void main() {
PORTB = 0;
TRISB = 0;
Usart_Init(19200); // Set up USART for reading the files
if (!Mmc_Fat_Init(&PORTC, 2)) { // Try to find the FAT
tmp = 0;
while (FAT_ERROR[tmp])
Usart_Write(FAT_ERROR[tmp++]);
}
for (loop = 1; loop <= 5; loop++) { // We want 5 files on our MMC card
filename[7] = loop + 64; // Set number 1, 2, 3, 4 or 5
Mmc_Fat_Assign(&filename); // If file not found, create new file
Mmc_Fat_Rewrite(); // Clear the file, start with new data
file_contents[0] = loop / 10 + 48;
file_contents[1] = loop % 10 + 48;
Mmc_Fat_Write(file_contents, 41); // Write data to the assigned file
Mmc_Fat_Append(); // Add more data to file
Mmc_Fat_Write(file_contents, 41); // Write data to file
Delay_ms(200);
}
// Now if we want to add more data to those same files
for (loop = 1; loop <= 5; loop++) {
filename[7] = loop + 64;
Mmc_Fat_Assign(&filename); // Assign a file
Mmc_Fat_Append();
Mmc_Set_File_Date(2005,6,21,10,loop,0);
Mmc_Fat_Write(" for mikroElektronika 2005\r\n", 30);
Mmc_Fat_Append();
Mmc_Fat_Write(file_contents, 41);
Mmc_Fat_Reset(&size); // To read file, returns file size
for (i = 1; i <= size; i++) { // Write whole file to USART
Mmc_Fat_Read(&character);
Usart_Write(character);
}
Delay_ms(200);
}
