DS3231

Open Phisatho opened this issue 6 years ago • 4 comments

I am not able to use DS3231 RTC along with sleep. Is there a way to avoid the sleep mode messing with DS3231 library?

To be precise, the RTClock.h is causing the trouble.

I believe that this library uses the RTC that is inside the STM32F103, not an extern RTC. The board must have the 32768kHz crystal like a BluePill board.

I am using Bluepill, but I wanted an accurate RTC like DS3231. I wonder if there is a way to use DS3231 for the same purpose that the internal RTC serves for this library.

Maybe this library https://github.com/flank1er/DS3231SQW but then you need to sleep and wake up on a pin interrupt
