Hello,

Anyone has already used the RTC DS1302 SPI - real-time clock - Waveshare 9709 ?
I cannot find a RTC library working through SPI with this clock.

Thanks,
Vincent

  • Going to urge you to use the DS3231, I2C RTC instead of the DS1302.

  • The DS3231 is far superior to the DS1302.

  • The DS1302 losses/gains too much time, minutes per month, the DS3231 is accurate to 1 or 2 seconds per month.
