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;

var counter : byte;                               // loop variable
begin

DDRA := 0xFF;
DDRB := 0xFF;

DDRC := 0xFF;

for counter := 0 to 31 do

// Fill data buffer

EEPROM_Write(0x100 + counter, counter);         // Write data to address

0x100+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;

procedure EEPROM_Write(address: word; wrdata: byte);

Nothing. 

Writes wrdata to specified address. 

Parameters : 

- 

address

: address of the EEPROM memory location to be written. 

- 

wrdata

: data to be written. 

Note: Specified memory location will be erased before writing starts.

Nothing.

var eeWrite : byte;

wrAddr : word;

...
address := 0x02;

wrdata := 0xAA;

EEPROM_Write(wrAddr, eeWrite);
