new component: Realtime clock RTC8563

[stefan.erni]

Hi Ben

On many M5 stack boards is the realtime clock IC RTC8563.

There is also an external module for just a few dollars.
This module also contains a 3 Volt battery.
It would be possible to use this module for example with the AppDevelopper or an ESP32 to set the time and date and then read the time with another module without wifi access. The time would be correct even with power interruption. ( I hope)

Would it be possible to make a component RTC8563 for Flowcode?

Hello,

I'll have a go, hopefully shouldn't be too tricky.

I've had a quick go and it should be available now via library updates.

Let me know how you get on if you have a go.

Hi Ben

I tested on a ESP32-S3 and it's working nice! Thank you very much.

One more question...
is it also possible to read a string like in the App-developer timestamp, which can be configured.
It would then be easy to have a time with an exact number of digits or a generated filename with other characters for separators

And what do I have to do, to set the time from the file SD mode (ESP32) so that the date and time created are correct?
