mikro c v5.6.1
pic 18f4550
20MHz oscilator(15pf)

Hello. I can't get lcd to work.He always shows squares. Frequency is set to 48 MHz.
Diplay is ok because he worked with pic 16f887.When I try 18f with led's(using diferent delays) he works ok.
here is code:

Code:
  // LCD module connections
sbit LCD_RS at latb4_bit;
sbit LCD_EN at latb5_bit;
sbit LCD_D4 at latb0_bit;
sbit LCD_D5 at latb1_bit;
sbit LCD_D6 at latb2_bit;
sbit LCD_D7 at latb3_bit;

sbit LCD_RS_Direction at TRISB4_bit;
sbit LCD_EN_Direction at TRISB5_bit;
sbit LCD_D4_Direction at TRISB0_bit;
sbit LCD_D5_Direction at TRISB1_bit;
sbit LCD_D6_Direction at TRISB2_bit;
sbit LCD_D7_Direction at TRISB3_bit;
// End LCD module connections


char txt1[] = "mikroElektronika";
char txt2[] = "EasyPIC6";
char txt3[] = "Lcd4bit";
char txt4[] = "example";

char i;                              // Loop variable

void Move_Delay() {                  // Function used for text moving
  Delay_ms(500);                     // You can change the moving speed here
}

void main(){
  adcon1=0x07;                        // Configure AN pins as digital I/O

  
  trisb=0;
  trisd=0;
  PORTB=0;
  Delay_ms(2000);
  portd=255;

  Lcd_Init();                        // Initialize LCD
  Delay_ms(2000);
  Lcd_Cmd(_LCD_CLEAR);               // Clear display
  Lcd_Cmd(_LCD_CURSOR_OFF);          // Cursor off
  Lcd_Out(1,6,txt3);                 // Write text in first row

  Lcd_Out(2,6,txt4);                 // Write text in second row
  Delay_ms(2000);
  Lcd_Cmd(_LCD_CLEAR);               // Clear display

  Lcd_Out(1,1,txt1);                 // Write text in first row
  Lcd_Out(2,5,txt2);                 // Write text in second row

  Delay_ms(2000);

  // Moving text
  for(i=0; i<4; i++) {               // Move text to the right 4 times
    Lcd_Cmd(_LCD_SHIFT_RIGHT);
    Move_Delay();
  }

  while(1) {                         // Endless loop
    for(i=0; i<8; i++) {             // Move text to the left 7 times
      Lcd_Cmd(_LCD_SHIFT_LEFT);
      Move_Delay();
    }

    for(i=0; i<8; i++) {             // Move text to the right 7 times
      Lcd_Cmd(_LCD_SHIFT_RIGHT);
      Move_Delay();
    }
  }
}
