void
Eeprom_Write(
char
address,
char
data);
Description
Writes data to the specified address. Parameter
address
is of byte type, which means it
can address only 256 locations. For PIC18 micros with more EEPROM data locations, it
is programmer’s responsibility to set SFR EEADRH register appropriately.
Be aware that all interrupts will be disabled during execution of EEPROM_Write rou-
tine (GIE bit of INTCON register will be cleared). Routine will set this bit on exit.
Requires
Requires EEPROM module.
Ensure minimum 20ms delay between successive use of routines
Eeprom_Write
and
Eeprom_Read
. Although PIC will write the correct value,
Eeprom_Read
might return
an undefined result.
Example
Eeprom_Write(0x32);
Eeprom_Read
unsigned short
i = 0, j = 0;
void
main() {
PORTB = 0;
TRISB = 0;
j = 4;
for
(i = 0; i < 20u; i++)
Eeprom_Write(i, j++);
for
(i = 0; i < 20u; i++) {
PORTB = Eeprom_Read(i);
Delay_ms(500);
}
