基于arduino+TM1637的计时器程序（包含倒计时、暂停功能）Proteus仿真

基于arduino的计时器（包涵倒计时、暂停、重置），在proteus8中仿真通过。用了两组1673的时钟芯片。
仿真原理图如下（proteus仿真工程文件可到本帖附件中下载）

Arduino代码如下：

#include <SevenSegmentTM1637.h>
#include <SevenSegmentExtended.h>
volatile int minute;
volatile int second;
volatile int order;
volatile int full;
volatile int empty;
volatile int setvalue;
volatile int topvalue;
boolean timerState=LOW;
SevenSegmentExtended display(8,9);
void setup(){
pinMode(2, INPUT);
minute = 0;
second = 0;
order = 0;
full = 0;
empty = 0;
setvalue = 5;
topvalue = 0;
display.begin();
order = 0;
// 倒计时时sencond与minute从full开始计时,顺计时从empty开始计时
if (order == 0) {
empty = 0;
full = 59;
minute = setvalue;
second = 0;
topvalue = 0;
} else {
empty = 59;
full = 0;
minute = 0;
// 设置为x分钟，加上秒钟走59，实际多走了一分钟，所以减一
topvalue = setvalue - 1;
}
attachInterrupt(digitalPinToInterrupt(2),interruptFun,LOW);
}
void loop(){
// 决定顺计时倒计时0为倒计时，1为顺计时
// 设置计时的最大数值
// 倒计时时topvalue=0时minute重置为setvalue
// 顺计时topvalue=setvalue值时被重置
// minute=0
if(timerState)
{
display.printTime(minute,second,true);
delayMicroseconds(1);
if (second == empty && minute == topvalue) {
if (order == 0) {
// 当minute达到设定的值则
minute = setvalue;
second = empty;
} else {
// 当minute达到设定的值则
minute = full;
second = full;
}
} else if (second == empty) {
if (order == 0) {
second = 59;
minute = minute - 1;
} else {
second = 0;
minute = minute + 1;
}
} else {
if (order == 0) {
second = second - 1;
} else {
second = second + 1;
}
}
}
}
void interruptFun()
{
timerState=!timerState;
digitalWrite(5,timerState);
// Inside the attached function, delay() won't work and the value returned by millis() will not increment.
// delay(5000);
}
