LCD với PIC18f4550

[trienst]

mình mới chuyển qua PIC18f, sau khi tham khảo chán chê mê mỏi các topic thì mình viết 1 đoạn code hiển thị lcd, tuy nhiên khi mô phỏng trên proteus thì ko thấy chạy, mình viết bằng C18, mong mọi người giúp đỡ
#include <p18cxxx.h>
#include<delays.h>
#include<xlcd1.h>
#include<xlcd1.c>
#pragma config PWRT = ON,BOR = OFF,WDT = OFF,PBADEN = OFF
unsigned char FullName[] ="NGUYEN TIEN TRIEN";
unsigned char Birthday[]="Date:22/02/1991";
//////////////////
void main(void)
{
unsigned char config = 0xFF,i=0,addr=0,data=0;
ADCON1 = 0xFF;
config = EIGHT_BIT & LINES_5X7;
PORTA=0;
PORTB=0;
//******** cau hinh LCD 8bit va ma tran hien thi 5x7 *********************************
OpenXLCD(config);
while(BusyXLCD()); //cho cho toi khi LCD het ban

//*********** HIEN THI ********
while (1)
{
WriteCmdXLCD(0x06);
SetDDRamAddr(0x00); //80
while(BusyXLCD()); //cho ban
putsXLCD(FullName); //hien thi FullName
while(BusyXLCD()); //cho ban
SetDDRamAddr(0xC0); //hien thi bat dau o dong thu 2
while(BusyXLCD()); //cho ban
putsXLCD(Birthday); //hien thi Birthday
while(BusyXLCD()); //cho ban
Delay10KTCYx(1000);
}
}

/* PIC18 XLCD peripheral routines.
*
* >>>>>>>>>>> MODIFIED BY DWD FOR THE PICDEM 2 PLUS LCD SETUP
*
* Notes:
* - These libraries routines are written to support the
* Hitachi HD44780 LCD controller.
* - The user must define the following items:
* - The LCD interface type (4- or 8-bits)
* - If 4-bit mode
* - whether using the upper or lower nibble
* - The data port
* - The tris register for data port
* - The control signal ports and pins
* - The control signal port tris and pins
* - The user must provide three delay routines:
* - DelayFor18TCY() provides a 18 Tcy delay
* - DelayPORXLCD() provides at least 15ms delay
* - DelayXLCD() provides at least 5ms delay
*/
