Cho mình hỏi
Code:
/* 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 */ Mình sửa file xlcd.h để giao tiếp 4 bit với LCD như này Code:
/********************************************************************/ /* Header for XLCD module library functions for */ /* P-tec PCOG1602B LCD controller */ /********************************************************************/ #if defined(__dsPIC30F__) #include <p30fxxxx.h> #elif defined(__dsPIC33F__) #include <p33Fxxxx.h> #elif defined(__PIC24H__) #include <p24Hxxxx.h> #endif #ifndef _XLCD_H #define _XLCD_H /* Comment out the following line if 4-bit interface is being used */ #define EIGHT_BIT_INTERFACE /* #defines of the data pins and the corresponding tris pins */ /* The READ_PIN_X #defines must match the corresponding DATA_PIN_X defines */ #define DATA_PIN_7 LATDbits.LATD3 #define DATA_PIN_6 LATDbits.LATD1 #define DATA_PIN_5 LATEbits.LATE8 #define DATA_PIN_4 LATCbits.LATC14 #define READ_PIN_7 PORTDbits.RD3 #define READ_PIN_6 PORTDbits.RD1 #define READ_PIN_5 PORTEbits.RE8 #define READ_PIN_4 PORTCbits.RC14 #define TRIS_DATA_PIN_7 TRISDbits.TRISD3 #define TRIS_DATA_PIN_6 TRISDbits.TRISD1 #define TRIS_DATA_PIN_5 TRISEbits.TRISE8 #define TRIS_DATA_PIN_4 TRISCbits.TRISC14 /* #defines of the control pins and the corresponding tris pins for 30F */ #define E_PIN LATCbits.LATC13 /* PORT for E */ #define RW_PIN LATBbits.LATB8 /* PORT for RW */ #define RS_PIN LATBbits.LATB7 /* PORT for RS */ #define TRIS_E TRISCbits.TRISC13 /* TRIS for E */ #define TRIS_RW TRISBbits.TRISB8 /* TRIS for RW */ #define TRIS_RS TRISBbits.TRISB7 /* TRIS for RS */ #ifdef EIGHT_BIT_INTERFACE #define DATA_PIN_3 LATDbits.LATD3 #define DATA_PIN_2 LATDbits.LATD2 #define DATA_PIN_1 LATDbits.LATD1 #define DATA_PIN_0 LATDbits.LATD0 #define READ_PIN_3 PORTDbits.RD3 #define READ_PIN_2 PORTDbits.RD2 #define READ_PIN_1 PORTDbits.RD1 #define READ_PIN_0 PORTDbits.RD0 #endif #ifdef EIGHT_BIT_INTERFACE #define TRIS_DATA_PIN_3 TRISDbits.TRISD3 #define TRIS_DATA_PIN_2 TRISDbits.TRISD2 #define TRIS_DATA_PIN_1 TRISDbits.TRISD1 #define TRIS_DATA_PIN_0 TRISDbits.TRISD0 #endif /* Display ON/OFF Control defines */ các phần sau thì giống file gốc Code:
#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;
