我有一个DS3231 RTC模块,我试图通过I2C使用我的Arduino UNO读取它的时间。我正在使用随库提供的示例代码,但它似乎不起作用。我无法获得DS3231 RTC的工作
我走出串行监控的唯一的事情是这样的:
20165-85-165 25:165:165 Temperature=254
我得到同样的事情与其他RTC模块以及和我的猜测(这可能是不正确的)是尽管似乎没有重置引脚,但它们可能会飞越。
#include <DS3231.h>
#include <Wire.h>
DS3231 Clock;
bool Century=false;
bool h12;
bool PM;
byte ADay, AHour, AMinute, ASecond, ABits;
bool ADy, A12h, Apm;
byte year, month, date, DoW, hour, minute, second;
void setup() {
// Start the I2C interface
Wire.begin();
#define oneTime
#ifdef oneTime
Clock.setSecond(50);//Set the second
Clock.setMinute(59);//Set the minute
Clock.setHour(11); //Set the hour
Clock.setDoW(5); //Set the day of the week
Clock.setDate(31); //Set the date of the month
Clock.setMonth(5); //Set the month of the year
Clock.setYear(13); //Set the year (Last two digits of the year)
#endif
// Start the serial interface
Serial.begin(115200);
}
void ReadDS3231()
{
int second,minute,hour,date,month,year,temperature;
second=Clock.getSecond();
minute=Clock.getMinute();
hour=Clock.getHour(h12, PM);
date=Clock.getDate();
month=Clock.getMonth(Century);
year=Clock.getYear();
temperature=Clock.getTemperature();
Serial.print("20");
Serial.print(year,DEC);
Serial.print('-');
Serial.print(month,DEC);
Serial.print('-');
Serial.print(date,DEC);
Serial.print(' ');
Serial.print(hour,DEC);
Serial.print(':');
Serial.print(minute,DEC);
Serial.print(':');
Serial.print(second,DEC);
Serial.print('\n');
Serial.print("Temperature=");
Serial.print(temperature);
Serial.print('\n');
}
void loop() {ReadDS3231();delay(1000);}
