MSP430f169的led动态显示

#include<msp430f169.h>

unsigned char Tab[10]={0x3F,0x06,0x5B,0x4F,0x66,0x6D,0x7D,0x07,0x7F,0x6F};
unsigned char Pos[4]={0x0E,0x0D,0x0B,0x07};
unsigned char Buf[4]={2,0,0,8};

void main(){
unsigned int n,j;
WDTCTL=WDTPW+WOTHOLD;
P1DIR|=0xFF;
P1OUT|=0XFF;
P2DIR|=0X0F;
P2OUT|=0X0F;

while(1){
for(n=0;n<4;n++){
P2OUT=Pos[n];
P1OUT=Tab[Buf[n]];
for(i=0;i<6000;i++);
}
    }
        }

通过视觉暂留的效应，只要灯闪的足够快，就可以实现动态显示。
