基于arduino+TM1637的計(jì)時器程序（包含倒計(jì)時、暫停功能）Proteus仿真

ID:141072 · 發(fā)表于 2021-10-25 11:06

基于arduino的計(jì)時器（包涵倒計(jì)時、暫停、重置），在proteus8中仿真通過。用了兩組1673的時鐘芯片。
仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）

Arduino代碼如下：

#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;
// 倒計(jì)時時sencond與minute從full開始計(jì)時,順計(jì)時從empty開始計(jì)時
if (order == 0) {
empty = 0;
full = 59;
minute = setvalue;
second = 0;
topvalue = 0;
} else {
empty = 59;
full = 0;
minute = 0;
// 設(shè)置為x分鐘，加上秒鐘走59，實(shí)際多走了一分鐘，所以減一
topvalue = setvalue - 1;
}
attachInterrupt(digitalPinToInterrupt(2),interruptFun,LOW);
}
void loop(){
// 決定順計(jì)時倒計(jì)時0為倒計(jì)時，1為順計(jì)時
// 設(shè)置計(jì)時的最大數(shù)值
// 倒計(jì)時時topvalue=0時minute重置為setvalue
// 順計(jì)時topvalue=setvalue值時被重置
// minute=0
if(timerState)
{
display.printTime(minute,second,true);
delayMicroseconds(1);
if (second == empty && minute == topvalue) {
if (order == 0) {
// 當(dāng)minute達(dá)到設(shè)定的值則
minute = setvalue;
second = empty;
} else {
// 當(dāng)minute達(dá)到設(shè)定的值則
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);
}
