EEPROM data memory is available with a number of PIC MCU models. Set of

library procedures and functions is listed below to provide you comfortable work

with EEPROM.

Basically, there are two operations that can be performed on EEPROM data mem-

ory.

function EEprom_Read(dim Address as byte) as byte

procedure EEprom_Write(dim Address as byte, dim Data as byte)

Library function EEprom_Read reads data from specified Address, while the

library procedure EEprom_Write writes Data to specified Address.

Parameter Address is of byte type, which means it can address only 256 locations.

For PIC18 MCU models with more EEPROM data locations, it is programmer's

responsibility to set SFR EEADRH register appropriately.

program EEPROMtest

dim i as byte

dim j as byte

main:

TRISB = 0

for i = 0 to 20

EEprom_write(i,i+6)

next i

for i = 0 to 20

PORTB = EEprom_read(i)

for j = 0 to 200

delay_us(500)

next j

next i

end.
