RTC S3031 (DFR1103) - How to enable 1Hz SQW on INT pin ?
Hello,
I am using modul DFR1103 ("Gravity: GNSS Position & Timing Module") with RTC chip SD3031.
I am able to configure/use 1sec pps output from gps module as interrupt, but I can't find how to enable RTC 1Hz SQW output to use it as 1sec interrupt for ESP32.
How can be 1Hz SQW output enabled on this module?
br,
Michal
