portinit.c

使用msp430f448测量脉冲宽度

#include "lcdhead.h"

void PortInit( void )
{  
     P1SEL = 0x00;
     P1DIR |= BIT4 + BIT6 + BIT7;
     P1DIR &= ~BIT2;
     P1DIR |= BIT1;
     P1SEL |= BIT2 + BIT1;           //P1.2为模块使用
     P1OUT &= ~BIT4;
     
     P2SEL = 0x00;
     P2DIR |= BIT0 + BIT1 + BIT2 + BIT6;
 
     P3SEL = 0X00;
     P3DIR = 0XFF;  
     
     P4SEL = 0x00;
     P4DIR |= BIT6 + BIT7;
     
     P6SEL = 0x00;
     P6DIR = 0xFF; 
     
     LCD_RD_HI;
