This Real Time Clock (RTC) is the most precise you can get in a small, low power package. Communication is via i2c. The default address is 0x57. The DS3231 library is installable directly from the Arduino Library Manager. 2032 Coin cell battery NOT included Features Dimension: 38mm* 22mm...
DS1307是常見的RTC IC,像是TinyRTC就使用DS1307。如果需要高精準度的RTC,可以使用DS3231。請先下載DS1307RTC library: https://github.com/ambiot/amb1_arduino/raw/master/Arduino_libraries/DS1307RTC-1.0.0.zip 另外時間格式的部份會用到Time library: https://github.com/ambiot/amb1_arduino/raw/master/...
1.将DS1307RTC文件夹放入Arduino程序位置的库文件夹中。 从DS1307到Arduino板的接线: GND - GND VCC - Arduino上的5v SDA - 模拟引脚4 SCL - 模拟引脚5 2.运行Arduino软件。 2.现在,DS1307RTC库应显示在文件示例-DS1307RTC中 4.在File-Examples-DS1307RTC下,有一个“ReadTest”和一个“SetTime”选项。...
manage certain hardware inside the DS3231 RTC module. This document explains the installation and usage of the Library with the Arduino IDE. You do have to install the Library in your Arduino IDE environment before you can use it. Installation instructions are provided, below. ...
DS3231是低成本、高精度I2C实时时钟(RTC),具有集成的温补晶振(TCXO)和晶体。该器件包含电池输入端,断开主电源时仍可保持精确的计时。集成晶振提高了器件的长期精确度,并减少了生产线的元件数量。DS3231提供商用级和工业级温度范围,采用16引脚300mil的SO封装。RTC保存秒、分、时、星期、日期、月和年信息。少于31天...
当Arduino本身具有内置计时器时，为什么我们实际上需要为Arduino项目提供单独的RTC。好吧，原因就是RTC模块...
This is a DS3231 high precision I2C RTC library for Arduino. Library features libccompatible Read/write date/timestruct tm Set/get Unix epoch UTCtime_t Set/get time (hour, min, sec) Set/get date and time (hour, min, sec, mday, mon, year, wday) Read temperature...
DS3231 RTC Description • 100% brand new and high quality Overview: • Raspberry Pi DS3231 foreign high precision clock module • Pay attention to the module for Arduino motherboard can also be used. • The module itself can be adapted to 3.3 V and 5 V system, no level conversion...
您将需要一个库，即RTC模块的库。因此，请首先从下面的链接下载该库，然后将其添加到Arduino IDE。
Library: DS3231 This library has been made to easily interface and use the DS3231 RTC with an Arduino or chipKit. The library will also work with the DS3232 RTC chip but you will not be able to use the internal SRAM. The DS3231 is a low-cost, extremely accurate I2C realtime clock ...
