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.

Floating inputs matters
[@C++ land] BTW, I have a library called avrIO that allows a better syntax that is type safe and without overhead if compared to avr-libc:
-
[C++@AVR8] Operations on I/O registers and I/O port pins
I have created a guide to help someone eventually interested to do a contribution to support a new MCU: https://github.com/ricardocosme/avrIO/blob/main/CONTRIBUTING.org
-
[C++] Operations on I/O registers and I/O port pins
I've updated avrIO to allow operations on multiple pins and also actions on registers and its respective bits.
-
[C++] Exploring type safety and expressiveness on IO registers
With avrIO the programmer can write:
-
[AVR8] C++20 Concepts and traits class to help abstract I/O port pins
Yes, I know it, but this snippet is from a C++11/17/20 library: avrIO.

C++ version to avr/interrupt.h and util/atomic.h
I wrote a C++ version to the the C headers avr/interrupt.h and util/atomi.h from AVR Libc. Nothing especial here, I'm using RAII to implement an atomic scope to execute a block of code instead the clever macro ATOMIC_BLOCK that uses a for loop and the GCC attribute cleanup. The macro functions cli/sei() were replaced by always_inline functions defined inside a namespace:
