WitrynaOn microcontrollers with built-in SPI interfaces, an SPI control or configuration register will have bits that control the polarity and phase. Because the RTC supports either polarity, the polarity can be set as desired. The phase bit, however, must be set properly, or the RTC will not operate correctly.

Witryna6 sty 2024 · The RTC upon resetting Arduino or removing power to the RTC reverts to 1/1/2000. So when the DS3231 library code runs again, it indicates that the RTC had lost power and sets it to current date and time. This behaviour occours when there is a non-rechargeable 3v battery attached to the module.
