3.13 Reading Serial Number

The driver supports reading the SAM device serial number (128 bit).‌

The SAMD51 function for reading SAM device serial number is DSCSAM_SerialNumberRead.‌

Step-By-Step Instructions

The user should call the function DSCSAM_SerialNumberRead() with an address of a integer buffer of size 128 bits as argument. Since size of integer is 32 bits, user can pass the address of an integer array of size four as argument.

...

ERRPARAMS errparams;  // structure for returning error code and error string
int serialnumber[4];
int index;

...

//Reading serial number

if( DSCSAM_SerialNumberRead(serialnumber) != DE_NONE )
{
		DSCGetLastError ( &errparams );
		printf ( "DSCSAM_SerialNumberRead error: %s %s\n", DSCGetErrorString ( errparams.ErrCode ), errparams.errstring );
		return 0;
}

// Printing serial number

printf("SAM Serial Number is:\n");		

for(index =0 ; index < 4;index++)
{
		printf("0x%x ",serialnumber[index]);
}
