portinit.c

本程序是LM2068R320*128的液晶显示驱动。呵呵！终于调出来了！

#include "lcdhead.h"

void PortInit( void )
{
//     P1SEL |= 0xEF;
     
     P6SEL = 0x00;
     P6DIR = 0xFF; 
     P6OUT = 0X00;
     
 //    P1DIR |= BIT4;
//     P1OUT &= ~BIT4;
//     P6OUT |= BIT0;
     
     P1SEL = 0X00;
     P1DIR |= BIT4 + BIT6 + BIT7;
     P1OUT |= BIT4;
    
//    P1DIR |= BIT6 + BIT7;
     P2SEL = 0x00;
     P2DIR |= BIT0 + BIT1 +BIT2;
//     P6SEL = 0x00;
//     P6DIR = 0xFF;
//     P6OUT = 0XFF;

     LCD_RD_HI;     
}
