Oleg,

If you make your routine a generic multibyte write to eeprom, that would be more useful methinks. Apart from that, your code is 'on the money'.

something like:

void write_bytes_to_eeprom(char *ptr,char num_bytes);


so to write a floating point number would be:

write_bytes_to_eeprom((char *)&float,sizeof(float));

writing a string would be:

write_bytes_to_eeprom(&string,strlen(string));

You would also have a corresponding read routine.
