RV-1805 Real Time Clock

Qwiic System
1

Hi,

I have 2 RV-1805s scheduled to arrive tomorrow, and am trying to prepare. I read through the examples on Git Hub as well as the IC datasheet. While there are examples shown to read the complete time, I am trying to read each unit individually, such as hours, minutes, seconds, and 100 ths of seconds. What commands should I use to read and write these?

Thanks,

Mark

The functions and such for the Arduino library are listed here https://learn.sparkfun.com/tutorials/qw … y-overview where you can re-arrange/incorporate the specific lines as needed

The application manual might also come in handy https://cdn.sparkfun.com/assets/0/8/4/2 … Manual.pdf, but I’d start with that 1st link
