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.

Should a driver module include a state machine or a task?
Here’s an extreme example for AVR (Atmega): https://github.com/jnaulet/OpenPicoRTOS/blob/main/drivers/twi/twi-avr.c

OpenPicoRTOS: 'cause the world DEFINITELY needs another RTOS !
It is small, fast, preemptive and offers support for SMP. It is available here for free: https://github.com/jnaulet/OpenPicoRTOS

What are some alternatives?
lfbb - A Lock Free Bipartite Buffer Library written in standard C11
simde - Implementations of SIMD instruction sets for systems which don't natively support them.
RIOT - RIOT - The friendly OS for IoT
QuarkTS - An open-source OS for embedded applications that supports prioritized cooperative scheduling, time control, inter-task communications primitives, hierarchical state machines and CoRoutines.
iota-c-library - embedded IOTA C library
freertos-teensy - FreeRTOS port with C++ std::thread support for ARM boards Teensy 3.5, 3.6, 4.0 and 4.1 (cortex-m4f and cortex-m7f)
web-of-thing-arduino - W3C Web of Things TD 1.0 comptaible library for the Arduino IDE. Especially the ESP32
atomicx - Pure C++ non stack displacement that implements cooperative multitask library for SINGLE CORE embedded development on DSPs, Microcontrollers and Processor (ARV, RISCV, ARM(all), TENSY, ESP), while also suitable for applications on Windows, Linux and MacOs and compatible with some RTOSs as well. This library allows full event driven applications while uses SMARTs LOCKS and WAIT/NOTIFY locks to also transport messages, MESSAGE BROKER is also provided (Those uses Message type size_t message and size_t tags, where tag will give meaning to the message). That implementation also introduce thread safe QUEUE (full object) and smart_ptr (to allow better implementation on minimal environment)
