51单片机开发板实验P0口显示加法P1口显示减法运算结果

这是一个基于51单片机开发板的实验，旨在展示如何在P0口和P1口分别显示加法和减法运算结果。本实验使用KEIL作为开发环境，编程语言为C语言。下面是程序源代码：

//头文件

#include

//定义P0口和P1口

sbit P0_0 = P0^0;

sbit P0_1 = P0^1;

sbit P0_2 = P0^2;

sbit P0_3 = P0^3;

sbit P0_4 = P0^4;

sbit P0_5 = P0^5;

sbit P0_6 = P0^6;

sbit P0_7 = P0^7;

sbit P1_0 = P1^0;

sbit P1_1 = P1^1;

sbit P1_2 = P1^2;

sbit P1_3 = P1^3;

sbit P1_4 = P1^4;

sbit P1_5 = P1^5;

sbit P1_6 = P1^6;

sbit P1_7 = P1^7;

//主函数

void main()

{

int a = 5;

int b = 3;

int sum = a + b;

int diff = a - b;

//P0口显示加法结果

P0_0 = sum & 0x01;

P0_1 = (sum>>1) & 0x01;

P0_2 = (sum>>2) & 0x01;

P0_3 = (sum>>3) & 0x01;

P0_4 = (sum>>4) & 0x01;

P0_5 = (sum>>5) & 0x01;

P0_6 = (sum>>6) & 0x01;

P0_7 = (sum>>7) & 0x01;

//P1口显示减法结果

P1_0 = diff & 0x01;

P1_1 = (diff>>1) & 0x01;

P1_2 = (diff>>2) & 0x01;

P1_3 = (diff>>3) & 0x01;

P1_4 = (diff>>4) & 0x01;

P1_5 = (diff>>5) & 0x01;

P1_6 = (diff>>6) & 0x01;

P1_7 = (diff>>7) & 0x01;
