Ameba Arduino: [RTL8195AM] [RTL8710AF] RTC - Using DS1307/DS3231 RTC as time source

Preparation

  • Ameba x 1
  • DS1307/DS3231 RTC x 1

Example

In this example we use DS1307/DS3231 RTC module as time source. The main difference between DS1307 and DS3231 is that DS3231 provides higher precision. The following two libraries are required:
Time:

The detailed description of DS1307/DS3231 please refer to the example of DS1307/DS3231.

If you are using TinyRTC, please connect the wires as follows:

Code Reference

This example uses RTC as time source:

setSyncProvider(RTC.get)

RTC.get() returns current time in unix-like format, and the returned value would be the time source of Time library.
