產(chǎn)品概述

產(chǎn)品是一款低功耗，具有56字節(jié)非失性RAM的全BCD碼時(shí)鐘日歷實(shí)時(shí)時(shí)鐘模塊，芯片可以提供秒，分，小時(shí)等信息，每一個(gè)月的天數(shù)能自動(dòng)調(diào)整。并且有閏年補(bǔ)償功能。AM/PM 標(biāo)志位決定時(shí)鐘工作于24小時(shí)或12小時(shí)模式，芯片有一個(gè)內(nèi)置的電源感應(yīng)電路，具有掉電檢測(cè)和電池切換功能。當(dāng)單片機(jī)斷電情況下，可以通過(guò)一個(gè)電池讓單片機(jī)項(xiàng)目時(shí)間保持記錄，完善的數(shù)據(jù)記錄。

規(guī)格參數(shù)

  1. 產(chǎn)品貨號(hào)：
  2. 工作電壓 ：+5v
  3. 主控芯片：DS1307
  4. 工作溫度范圍：0°C to +70°C
  5. 接口類(lèi)型：IIC 通信接口
  6. 固定孔：4個(gè) * M3
  7. 產(chǎn)品尺寸：45mm * 25mm

接口定義

RTC時(shí)鐘模塊引腳定義：

  • SDA：I2C 數(shù)據(jù)引腳
  • SCK：I2C 時(shí)鐘引腳
  • +：電源(VCC)
  • -：地(GND)

例子程序

將下列程序上傳到 Carduino 控制器中

將下載到的壓縮文件解壓到到 Arduino IDE 軟件的 libraries 文件中（·····\arduino-1.7.6\libraries），啟動(dòng) Arduino IDE 選擇文件 -- 示例 -- RB-02S101_RTC_Module-master -- 打開(kāi) example - ds1307 例子程序，上傳到 Arduino UNO 控制器中，就可以實(shí)現(xiàn)代碼測(cè)試。操作方法下圖所示：
