单片机流水灯代码

具体如下。
#include，sbitLED1=P1^0;//定义0/1变量，是因为在电路中一般为高电压以及低电压两种，也就是代表者0或1。sbitLED2=P1^1;sbitLED3=P1^2;sbitLED4=P1^3;sbitLED5=P1^4;sbitLED6=P1^5;sbitLED7=P1^6。
单片机（Microcontrollers）又称微控制器，由中央处理器、存储器、输入输出端口(包括并行I/O、串行I/O、模数转换器)、计时器和计数器等组成，具有完整数字处理功能的大规模集成电路。微控制器是一种面向控制领域嵌入式应用的集成化计算机芯片，主要用于工业控制、数据处理、信号处理、智能仪器、通信产品及民用消费产品等自动控制产品与器件中。通常也把它简称为MCU或μC，MCU配以适当的外围设备和软件就可构成一个计算机应用系统，所以也称之为单片微型计算机，简称为单片机。

#include //52系列单片机头文件
#include //_crol_ 字符循环左移
#define uint unsigned int //宏定义
#define uchar unsigned char//宏定义
void delayms(uint); //声明子函数
uchar a; //定义uchar类型的变量a
void main() //主函数
{
a=0xfe; //赋初值11111110
while(1) //大循环
{
P1=a;
delayms(500); //延时500毫秒
a=_crol_(a,1); //将a循环左移1位后再赋给a
}
}
void delayms(uint xms) //延时函数
{
uint i,j;
for(i=xms;i>0;i--) //i=xms即延时约xms毫秒
for(j=110;j>0;j--);
}
学习单片机，还需要结合实际硬件电路来编程

你从microchip官网上下一些PIC32的例程就行啦，各种外设接口的例程都有，下面是定时中断的一个例程。在Debug模式下能正常进中断，RD0接口的LED闪烁表示芯片是好的
