c++ - 这个Arduino sleep setAlarm函数的周长是多少？

RTC.setAlarm(ALM1_MATCH_HOURS, 33, 18, 0); //set your wake-up time here
是33秒18分钟零小时吗？

自述文件引用了它的Adafruit库。从那里，我找不到实际在哪里说setAlarm的参数。

adafruit.github.io/RTClib

adafruit.github.io/RTClib/html/class_r_t_c___d_s3231.html

github.com/adafruit/RTClib

库(在草图中)如下:

#include <Wire.h>
#include <RTClibExtended.h>
#include <LowPower.h>

最佳答案

看起来它也来自另一个库。我只是搜索了代码本身，发现了这个:https://github.com/JChristensen/DS3232RTC#alarm-methods

  RTC.setAlarm(ALM1_MATCH_SECONDS, 30, 00, 0, 0);   //set your wake-up time here:
  RTC.setAlarm(ALM2_MATCH_MINUTES, 0, 10, 0, 0);  //where "xx" is minutes
  // every 00 minutes past the hour;
  // if every minute is needed change MINUTES to SECONDS (only for ALM1)
  // matches seconds AND minutes when _MINUTES is used. Sequence of time:
  // first seconds, then minutes, hours, daydate
  // or: seconds (but enter 00, is ignored), minutes then hours, daydate for ALM2
  // zero's mean: always
  // example: Set alarm1 every day at 18:33
  // RTC.setAlarm(ALM1_MATCH_HOURS, 33, 18, 0);  set your wake-up time here
  // RTC.alarmInterrupt(1, true);

因此，闹钟每天设置为18:33。
RTC.setAlarm(ALM1_MATCH_HOURS, [minute], [hour], 0);
