msp430基于proteus的基本程序

1、1、LED灯、数码管、蜂鸣器的控制，闪烁的实现，流水灯的实现：程序2.1.1：#include "io430.h"int main( void ) unsigned int i; long int j,k; unsigned a=0x40,0x79,0x24,0x30,0x19,0x12,0x02,0x78,0x00,0x10,0x88,0x80,0xc6,0xc0,0x86,0x8e; /P2输出数组 / Stop watchdog timer to prevent time out reset WDTCTL = WDTPW + WDTHOLD; P2DIR=0xFF;P

2、1DIR=0x1F; while(1) for(j=0;j<200000;j+) P2OUT=a0; P1OUT=0x1F; for(j=1;j<=16;j+) for(i=0;i<j;i+) P2OUT=aj; for(k=0;k<6000/(j+1);k+) P1OUT=0xE0; for(k=0;k<6000/(j+1);k+) P1OUT=0x1F; 此程序包括了LED灯、数码管、蜂鸣器的使用。功能是当数码管显示0F时，LED灯分别闪几下，蜂鸣器分别响几下。如图2.1图2.1 数码管示数和LED灯闪烁程序2.1.2：#include "msp43
