hi friends,

I have problem with store the int32 variable in memory...I use below function to read and write int32 variable in memory...

Code:

int32 READ_INT32_EEPROM(int32 n)
{
   int i;
   int32 data;
   restart_wdt();
   for (i = 0; i < 4; i++)
   {
        *(&data + i) = read_eeprom(i + n);//i
   }
    return(data);
}
///////////////////////////////////////////////////////////////////////////////
void WRITE_INT32_EEPROM(int32 n, int32 data)
{
    int32 i;
    restart_wdt();   
    for (i = 0; i < 4; i++)
    {
        write_eeprom(i + n, *(&data + i) ) ;
    }
}

Look at this CCS FAQ article:
http://www.ccsinfo.com/faq.php?page=write_eeprom_not_byte
Also, read some other forum posts, because a similar topic
was answered only a few hours ago.

In the write routine (in the link above) make these changes:
Quote:

Change 'WRITE_FLOAT_EXT_EEPROM' to 'Write_int32_eeprom'
Change 'float data' to 'int32 data'
Change 'write_ext_eeprom' to 'write_eeprom'


In the read routine (in the link above) make these changes:
Quote:

Change 'float READ_FLOAT_EXT_EEPROM' to 'int32 read_int32_eeprom'
Change 'float data' to 'int32 data'
Change 'read_ext_eeprom' to 'read_eeprom'


The eeprom address must be increased by 4 bytes, each time you
write a new int32 value.
