This example demonstrates using the EEPROM Library with ATmega16 MCU.

First, some data is written to EEPROM in byte and block mode; then the data is read
from the same locations and displayed on PORTA, PORTB and PORTC.

program EEPROM

dim counter as byte   

' loop variable

main:

DDRA = 0xFF

DDRB = 0xFF

DDRC = 0xFF

for counter = 0 to 31                   

' Fill data buffer

EEPROM_Write(0x100 + counter, counter)     

' Write data to

address 0x100+counter

next counter

EEPROM_Write(0x02,0xAA)

' Write some data at address 2

EEPROM_Write(0x150,0x55) ' Write some data at address 0x150

Delay_ms(1000)          ' Blink PORTA and PORTB diodes
PORTA = 0xFF        

'   to indicate reading start

PORTB = 0xFF
Delay_ms(1000)
PORTA = 0x00

PORTB = 0x00
Delay_ms(1000)

PORTA = EEPROM_Read(0x02)                      ' Read data from

address 2 and display it on PORTA

PORTB = EEPROM_Read(0x150)                     ' Read data from

address 0x150 and display it on PORTB

Delay_ms(1000)

for counter = 0 to 31 

' Read 32 bytes block from address 0x100

PORTC = EEPROM_Read(0x100+counter)          '   and display

data on PORTC

Delay_ms(100)

next counter

end.
