实现米思齐的数码管图形化编程。

1.实现滚动显示自定义字符串。

#include <SevenSegmentTM1637.h>

SevenSegmentTM1637  display(5,6);

void setup(){
   display.begin();
  display.print("ABCD");
}

void loop(){

}

2.实现显示自定义时间。

#include <SevenSegmentTM1637.h>

SevenSegmentTM1637  display(5,4);

void setup(){
   display.begin();
}

void loop(){
  display.print("3689");

}

3.实现显示秒表。

#include <EEPROM.h>
#include <avr/pgmspace.h>
#include <TimerOne.h>

int8_t TimeDisp[] = {0x00,0x00,0x00,0x00};
unsigned char ClockPoint = 1;
unsigned char Update;
unsigned char microsecond_10 = 0;
unsigned char second;
unsigned char _microsecond_10 = 0;
unsigned char _second;
unsigned int eepromaddr;
boolean Flag_ReadTime;

#define ON 1
#define OFF 0

 void TimeUpdate(void){  if(ClockPoint)tm1637.point(POINT_ON);  else tm1637.point(POINT_OFF);   TimeDisp[0] = hour / 10;  TimeDisp[1] = hour % 10;  TimeDisp[2] = minute / 10;  TimeDisp[3] = minute % 10;  Update = OFF;}
void TimeUpdate2(void)
{
if(ClockPoint)tm1637.point(POINT_ON);
else tm1637.point(POINT_OFF);
TimeDisp[2] = _microsecond_10 / 10;
TimeDisp[3] = _microsecond_10 % 10;
TimeDisp[0] = _second / 10;
TimeDisp[1]= _second % 10;
Update = OFF;
}

void TimingISR()
{
halfsecond ++;
Update=ON;
if(halfsecond == 2){
second ++;
if(second==60)
{
minute ++;
if(minute == 60){
hour ++;
if(hour == 24)
hour = 0;
minute = 0;
}
second = 0;
}
halfsecond = 0;
}
ClockPoint=(~ClockPoint) & 0x01;
}
void TimingISR2()
{
microsecond_10 ++;
Update = ON;
if(microsecond_10 == 100)
{
second ++;
if(second == 60)
{
second = 0;
}
microsecond_10 = 0;
}
ClockPoint =(~ClockPoint) & 0x01;
if(Flag_ReadTime == 0)
 {_microsecond_10 = microsecond_10;
_second = second;  }
}

void readTime(){
Flag_ReadTime = 1;
if(eepromaddr == 0)
{
Serial.println("The time had been read");
_microsecond_10 = 0;
 _second = 0;
}
else{
_second = EEPROM.read(-- eepromaddr);
_microsecond_10 = EEPROM.read(-- eepromaddr);
Serial.println("List the time");
}
Update = ON;
}
void saveTime()
{EEPROM.write(eepromaddr ++,microsecond_10);
EEPROM.write(eepromaddr ++,second);
}

void stopwatchPause()
{
TCCR1B &= ~(_BV(CS10) | _BV(CS11) | _BV(CS12));
}

void stopwatchReset()
{
 stopwatchPause();
Flag_ReadTime = 0;
_microsecond_10 = 0;
_second = 0;
microsecond_10 = 0;
second = 0;
Update = ON;
}

void stopwatchStart()
{
  Flag_ReadTime = 0;
TCCR1B |=Timer1.clockSelectBits;
}

void setup(){
  tm1637.init();
Timer1.initialize(500000);
  Timer1.attachInterrupt(TimingISR);

    tm1637.set();
 tm1637.init();
Timer1.initialize(10000);
  Timer1.attachInterrupt(TimingISR2);

}

void loop(){
   if(Update == ON){TimeUpdate();tm1637.display(TimeDisp);}stopwatchStart();
  if(Update == ON)
  {
  TimeUpdate2();
  tm1637.display(TimeDisp);
  }
}
