1.DS3231模块初次使用时需用adjust(constDateTime &dt)函数设置时间。 2.DS3231模块自带纽扣电池,在断电后仍可继续计时,确保数据不丢失。 下面介绍如何为DS3231设置时间以及电池失效后的处理方法。 adjust(constDateTime &dt) 功能:为DS3231模块设置日期 参数:DataTime对象 具体用法如下 第11行的rtc.adjust(DataTime(...
DateTime now = rtc.now(); // 获取 rtc 时间并在显示中打印 lcd.clear(); lcd.setCursor(0, 0); lcd.print("时间:"); lcd.setCursor(6, 0); lcd.print(nowHr = now.hour(), DEC); lcd.print(":"); lcd.print(nowMin = now.minute(), DEC); lcd.print(":"); lcd.print(nowSec = n...
