DS3231-RTC Library The great C++ Library for the DS3231 real-time clock (RTC) module. Description The library provides easy-to-use methods to: set and read the current date and time; set, clear, and detect two, independent, Time-of-Day alarms; perform certain conversions and calculations ...
DS1307/DS3231 RTC x 1 范例说明 这个范例里会使用NTP来对DS1307/DS3231 RTC模组做时间校正我们需要这几个library: DS1307RTC library:https://github.com/ambiot/amb1_arduino/raw/master/Arduino_libraries/DS1307RTC-1.0.0.zip Time library:https://github.com/ambiot/amb1_arduino/raw/master/Arduino_lib...
这个范例里使用DS1307/DS3231 RTC模组当作时间的来源。 DS1307与DS3231都是RTC模组,主要差异是DS3231的精准度较高。我们需要的library有Time:https://github.com/ambiot/amb1_arduino/raw/master/Arduino_libraries/Time-1.0.1.zip DS1307RTC:https://github.com/ambiot/amb1_arduino/raw/master/Arduino_librarie...
