我有一个 DS3231 RTC 模块,我正在尝试使用我的 Arduino UNO 通过 I2C 读取它的时间。我正在使用库提供的示例代码,但它似乎不起作用。
我从串行监视器中得到的唯一结果是:
20165-85-165 25:165:165
Temperature=254
我对另一个 RTC 模块也得到了同样的结果,我的猜测(可能不是真的)是它们可能已经溢出,尽管似乎没有复位引脚。
#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(hour,DEC);

Serial.print("Temperature=");
Serial.print(temperature);
Serial.print('\n');

void loop() {ReadDS3231();delay(1000);}
