Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Examples for Dual-mode I2C on newer AVR-0 parts?
Did you browse the examples here: https://github.com/SpenceKonde/DxCore/tree/master/megaavr/libraries/Wire/examples ?
-
Trying to monitor battery voltage on ATMega 808-XFR
This looks similar to what is available on the newer Dx family. The Arduino core documents this, so it may be worth reading through the source to see how it is achieved: https://github.com/SpenceKonde/DxCore/blob/master/megaavr/extras/Ref_Analog.md

Alternatives to Atmega328P and Atmel Studio
As I mentioned upthread, there is a very good Arduino core for the Dx chips. Even if you don't use it, the documentation alone is worth reading through: (https://github.com/SpenceKonde/DxCore). The same author also maintains cores for various ATTiny families.

Swapping to AVR128DB
DxCore tells the Arduino IDE how to use the DA/DB series... https://github.com/SpenceKonde/DxCore

Building an Arduino on a breadboard - troubles I faced.
I'm a great fan of the newer AVR-DA and -DB chips as they offer much more value for money. They run at 24MHz without a crystal, have 16K SRAM and 128KB flash, more peripherals (e.g. two UARTs) and can be programmed with just a USB/serial adapter (no hardware programmer required). Available in the same 28-pin DIP package for about the same price. There's an excellent Arduino core available with full instructions: https://github.com/SpenceKonde/DxCore

Atmega2560-16au substitute?
The newer chips are really easy to use. All the chip really needs is the usual soft reset circuit (10K resistor + 100nF cap) and a 100nF cap on each power pin. Read through the readme's here: https://github.com/SpenceKonde/DxCore

What IC can I use instead of an AtMega, that can run on a 3V lithium battery? I don't want to change the system clock.
Try the new AVR-Dx family. Still familiar AVR but will run at 24MHz down to 1.8V without a crystal. You can pick up e.g. AVR128DA28 in 28 pin DIL with 16K RAM and 128K flash for a couple of pounds/dollars/euros. Put it on some strip board with a couple of capacitors and resistors.
