Library Example

The following code tests MMC library routines. First, we fill the buffer with 512 “M” characters

and write it to sector 56; then we repeat the sequence with character “E” at sector 56. Finally, we

read the sectors 55 and 56 to check if the write was successful.

unsigned i;

unsigned short tmp;

unsigned short data[512];

void main() {

Usart_Init(9600);

// Wait until MMC is initialized

while (Mmc_Init(&PORTC, 2)) ;

// Fill the buffer with the 'M' character

for (i = 0; i <= 511; i++) data[i] = "M";

// Write it to MMC card, sector 55

tmp = Mmc_Write_Sector(55, data);

// Fill the buffer with the 'E' character

for (i = 0; i <= 511; i++) data[i] = "E";

// Write it to MMC card, sector 56

tmp = Mmc_Write_Sector(56, data);

/** Now to check sectors 55 and 56 **/

// Read from sector 55

tmp = Mmc_Read_Sector(55, data);

// Send 512 bytes from buffer to USART

if (tmp == 0)

for (i = 0; i < 512; i++) Usart_Write(data[i]);

// Read from sector 56

tmp = Mmc_Read_Sector(56, data);

// Send 512 bytes from buffer to USART

if (tmp == 0)

for (i = 0; i < 512; i++) Usart_Write(data[i]);

}
