I was wondering if there is any way to keep the internal RTC clock of the TinyScreen+ to keep the time and date while the TinyScreen+ is off. My TinyScreen+ has a battery on it, so ideally the battery would keep the RTC going.

Thank you! I actually did not know that there was a tutorial on that subject. Thank you very much!
