Các vấn đề với C30

Cho mình hỏi

/* defines for segment data transfer direction */
#define SEG1_50_SEG51_100     0x39  /* SEG1->SEG50 ,SEG51->SEG100 */
#define SEG1_50_SEG100_51     0x3d  /* SEG1->SEG50 ,SEG100->SEG51 */
#define SEG100_51_SEG50_1     0x3b  /* SEG100->SEG51,SEG50->SEG1 */
#define SEG100_51_SEG1_50     0x3f  /* SEG100->SEG51,SEG1->SEG50 */

/* defines for COM data transfer direction */

#define COM1_COM16            0x3e  /* Data transfer direction is COM1 to COM16 */

#define COM16_COM1            0x3f  /* Data transfer direction is COM16 to COM1 */

2 cái difine này có tác dụng j thế hả bạn

Mình sửa file xlcd.h để giao tiếp 4 bit với LCD như này

các phần sau thì giống file gốc

chương trình chính mình viết giống như bạn chỉ thay 8 bit thành 4 bit

#include <p30f4011.h>
#include "xlcd.h"

_FOSC(CSW_FSCM_OFF & FRC_PLL4);
_FWDT(WDT_OFF);
_FBORPOR(PBOR_ON & BORV_27 & PWRT_16 & MCLR_DIS);
_FGS(CODE_PROT_OFF);

void main()
{
    OpenXLCD(FOUR_BIT & TWO_LINE & SEG1_50_SEG51_100
             & COM1_COM16);    //Khoi tao lcd
    PutsXLCD("Hello world");   //Hien thi mot xau tren dong thu nhat
	
    SetDDRamAddr(0x40);        //Dua con tro ve dau dong thu hai
    PutsXLCD("30f4011-LCD");	//Hien thi mot xau tren dong thu hai
    
    while(1);
    return 0; 
}

Khi dịch ra thì báo là

Mình vẫn ko hiển thị dc lên LCD, phần in đậm là lỗi j thế

[0509592]

các bác ơi!
sao em không thấy ai bàn về chủ đề PIC24????
em muốn nghiên cứu về PIC24 nhưng không biết dòng PIC24 nào phổ biến????
tìm trên diễn đàn thì không thấy bàn về PIC24???
các bác giúp em với????
thanks!
