This is code for Keil C. Good to save a structure that you define.

Givens : The structure is called Settings
The structure is declared
bp is a pointer to a byte
NVRwrite is a function to write a byte to the eeprom
first param is address, second is the byte to write

// save the settings to EEPROM
void  Settings_Put()
{
byte   cnt, 
       *bp;
uint   addr=0;   // where to save the structure

  // point to the settings variable
  bp = (byte *)&Settings;

  // write the settings
  for (cnt = 0; cnt < sizeof(Settings); cnt++)
  {
    NVRwrite(addr++, *bp++);
  }
}

For all you know, Settings could just be a float. For an array, you need to use the strlen function to find the length of the string to save.

Again - This code is for Keil C
