EEPROM Library

EEPROM Library

EEPROM data memory is available with a number of PIC MCUs. mikroC PRO for PIC includes library for comfortable work with EEPROM.

Library Routines

• EEPROM_Read
• EEPROM_Write
• Library Example

EEPROM_Read

// for PIC16
unsigned short EEPROM_Read(unsigned short address);

// for PIC18
unsigned short EEPROM_Read(unsigned int address);

unsigned short take;
...
take = EEPROM_Read(0x3F);

EEPROM_Write

// for PIC16
void EEPROM_Write(unsigned short address, unsigned short data);

// for PIC18
void EEPROM_Write(unsigned int address, unsigned short data);

EEPROM_Write(0x32, 19);

Library Example 

char ii;                                 // loop variable

void main(){
  ANSEL =  0;                            // Configure AN pins as digital I/O
  ANSELH = 0;
  C1ON_bit = 0;                          // Disable comparators
  C2ON_bit = 0;

  PORTB = 0;
  PORTC = 0;
  PORTD = 0;

  TRISB = 0;
  TRISC = 0;
  TRISD = 0;
   
  for(ii = 0; ii < 32; ii++)             // Fill data buffer
    EEPROM_Write(0x80+ii, ii);           // Write data to address 0x80+ii

  EEPROM_Write(0x02,0xAA);               // Write some data at address 2
  EEPROM_Write(0x50,0x55);               // Write some data at address 0150

  Delay_ms(1000);                        // Blink PORTB and PORTC LEDs
  PORTB = 0xFF;                          //   to indicate reading start
  PORTC = 0xFF;
  Delay_ms(1000);
  PORTB = 0x00;
  PORTC = 0x00;
  Delay_ms(1000);

  PORTB = EEPROM_Read(0x02);             // Read data from address 2 and display it on PORTB
  PORTC = EEPROM_Read(0x50);             // Read data from address 0x50 and display it on PORTC

  Delay_ms(1000);

  for(ii = 0; ii < 32; ii++) {           // Read 32 bytes block from address 0x80
    PORTD = EEPROM_Read(0x80+ii);        //   and display data on PORTD
    Delay_ms(250);
    }
