1 year ago Hi @kangooF. Thanks for your interest in this open source project. This issue tracker is only to be used to report bugs or feature requests specific to the project. This topic is more appropriate for the Arduino Forum. I'm sure we will be able to help you out over there:
The problems I have encountered are more than one. Hardware, to use the internal clock which could also be convenient but forces to keep the 3.3 volt line powered with a buffer battery + diode powered by the whole circuit to which it gives power to sensors, various hardware and therefore with high battery consumption. As if that were not enough it seems inaccurate (he lost about ten minutes in a day), if I try to return to the external i2c card with ds1307 it doesn't work, with the ds3231 it does not compile the IDE 2.0. How do I solve the problem?
