hi,
D.narender Reddy said:
i need to write a floating point type number into EEPROM. how do u do this. iam using C language and ke*il u vison to write the program.
What is about to store float number byte-by-byte? void Write_float_to_EEPROM (float number)
{
// make some temporal variables
unsigned char x, a, *ptr;
// do loop for all bytes of float number via its address location
for (x=sizeof(float), ptr=(unsigned char *)&number; x>0; x--)
{
a = *ptr++;
Write_byte_to_EEPROM(a);
}
}Seems it should work?
