标题: 自制Arduino库-基于时间值的无延时处理
我们知道，Arduino里要多个LED灯能基于不同的延时值来亮灭，用普通的Delay是无法达到效果。一般要么上系统，要么用分时的方法，而本人基于数组和Millis()函数自制一个库，实现类似于时间继电器延时ON和OFF的功能，很方便能使用。以下为本人原创，网友可自行研究改进

一、先看库的头文件

#ifndef_DelayRun_h

#define_DelayRun_h

#defineMAX_DELAY 10

#defineIF_DELAY_OFF(a,b,c) if(DelayRun.delay_off(a,b,c))

#defineIF_DELAY_ON(a,b,c) if(DelayRun.delay_on(a,b,c))

#defineIF_DELAYUS_OFF(a,b,c) if(DelayRun.delayus_off(a,b,c))

#defineIF_DELAYUS_ON(a,b,c) if(DelayRun.delayus_on(a,b,c))

#defineIF_RUN_ONCE(a,b) if(DelayRun.once_func(a,b))

#defineIF_RUN_NORMAL(a) if(DelayRun.normal_func(a))

#defineWHILE_DELAY_OFF(a,b,c) while(DelayRun.delay_off(a,b,c))

#defineWHILE_DELAY_ON(a,b,c) while(DelayRun.delay_on(a,b,c))

#defineWHILE_DELAYUS_OFF(a,b,c) while(DelayRun.delayus_off(a,b,c))

#defineWHILE_DELAYUS_ON(a,b,c) while(DelayRun.delayus_on(a,b,c))

//For Arduino 1.0

#if ARDUINO>= 100

#include<Arduino.h>

#else

#include<WProgram.h>

#endif

#include "DelayRun.h"

uint32_t delaytick[MAX_DELAY];

//自定义延时程序

{

}

if(delaytick[index]==0)

delaytick[index]=millis()+delaytime;

if(millis()>=delaytick[index])

{

runstate[index]=0;

runstate[setindex]=1;

return 1;

}

else

{

return 0;

}

{

{

}

三、把制作的库放在ArduinoIDE的Libraries文件库里，然后在自己的Arduino里使用，见如下Sample
本示例实现数字口2、3不同的时基闪灭,互不干扰，4为按键，按下后，5延时LOW
#include <DelayRun.h>
//IF_DELAY_OFF(a,b,c)  if(DelayRun.delay_off(a,b,c))
//IF_DELAY_ON(a,b,c)  if(DelayRun.delay_on(a,b,c))
//IF_DELAYUS_OFF(a,b,c)  if(DelayRun.delayus_off(a,b,c))
//IF_DELAYUS_ON(a,b,c)  if(DelayRun.delayus_on(a,b,c))
//IF_RUN_ONCE(a,b)  if(DelayRun.once_func(a,b))
//IF_RUN_NORMAL(a)  if(DelayRun.normal_func(a))
//WHILE_DELAY_OFF(a,b,c)  while(DelayRun.delay_off(a,b,c))
//WHILE_DELAY_ON(a,b,c)  while(DelayRun.delay_on(a,b,c))
//WHILE_DELAYUS_OFF(a,b,c)  while(DelayRun.delayus_off(a,b,c))
//WHILE_DELAYUS_ON(a,b,c)  while(DelayRun.delayus_on(a,b,c))
uint8_t key2;
uint8_t runstate[MAX_DELAY];
void setup() {
  // put your setup code here, to run once:
  pinMode(2,OUTPUT);
  pinMode(3,OUTPUT);
  pinMode(4,INPUT);
  pinMode(5,OUTPUT);
  runstate[0]=1;
  runstate[2]=1;
  runstate[4]=1;
}

void loop() {
  // put your main code here, to run repeatedly:
  //if(DelayRun.delay_off(1000,0,1))
  IF_DELAY_OFF(1000,0,1)
  {
digitalWrite(2,HIGH);
  }
  IF_DELAY_OFF(1000,1,0)
  {
digitalWrite(2,LOW);
  }
  IF_DELAY_OFF(300,2,3)
  {
digitalWrite(3,HIGH);
  }
  IF_DELAY_OFF(300,3,2)
  {
digitalWrite(3,LOW);
  }
  if(digitalRead(4)==LOW)
  {
delay(10);
if(digitalRead(4)==LOW)
{
   key2=1;
}
  }
  if(key2)
  {
   IF_RUN_ONCE(4,5)
{
   digitalWrite(5,HIGH);
}
   IF_DELAY_ON(1000,5,4)
{
   digitalWrite(5,LOW);
   key2=0;
}
  }
}
