arduino学习笔记之Tiny RTC 12C 时钟模块
之前的学习笔记中有一篇“arduino学习笔记之DS1307 RTC时钟芯片与DS18B20数字温度传感器实验”现在看来那个文章稍微有点“旧了”今天更新一个新库使用更方便
以下为控制代码:
【库文件:RTClib】
#include
#include
RTC_DS1307 RTC;
void setup () {
Serial.begin(9600);
Wire.begin();
RTC.begin();
if (! RTC.isrunning()) {
Serial.println("RTC is NOT running!");
RTC.adjust(DateTime(__DATE__, __TIME__));
}
}
void loop () {
DateTime now = RTC.now();
Serial.print(now.year(), DEC);
Serial.print('/');
Serial.print(now.month(), DEC);
Serial.print('/');
Serial.print(now.day(), DEC);
Serial.print(' ');
Serial.print(now.hour(), DEC);
Serial.print(':');
Serial.print(now.minute(), DEC);
Serial.print(':');
Serial.print(now.second(), DEC);
Serial.println();
delay(1000);
}
--end--
