@k-nowicki Thanks for your pull request. I like the idea to add an additional interface to select a different I2C (TwoWire) bus.

I started with a code review and integration test and have some findings:

1. AVR integration tests failed with build errors on include file wire.h instead of Wire.h. Maybe there is a difference between architectures.
2. For which architecture are macro's ENERGIA and __arc__ set?
3. When the build passes for AVR, ESP8266, ESP32, DUE and RP2040, the (README.md)[https://github.com/Erriez/ErriezDS3231/blob/master/README.md] and library.*should be updated.

FYI: Maintenance added to my Todo list (spare time):

1. This library was still using the old deprecated Travis which should be upgraded to use Github Actions.
2. I deprecated CMakeLists.txt for CLion a while ago as it is broken (already removed in my other libraries).
3. I'll create a footprint difference as RAM availability is limited for AVR.

Are you sure it is included in the lib? I can only see the capitalized version.

For which architecture are macro's ENERGIA and arc set?

Aren't they project specific? This lib do not need them and I have no such macros defined.

(README.md)... and library.* should be updated.

You are absolutely right. I have updated README and maked new pull request. In case of library.* files I am unsure how to update them correctly.

I am using ESP-IDF framework and toolchain on Esp32 platform.
I have not tested it on Arduino IDE nor other MCU, but changes made with this pull request should not affect platform compatibility.
