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.

Layout of Rust's u128 and i128 changed
I needed 128-bit and 256-bit integers on an embedded project recently.
In short, it was for fixed-point digital signal processing. The raw input and output samples were int64_t. We needed to add, subtract, multiply, and accumulate these to do filtering and linear regression with no loss of precision.
Conventional bigintegers weren't an option because the target application doesn't allow heap allocation. So we rolled our own [1] stack-allocated, fixed-width big integer class.

CRC32 algorithm match value between 96 bit wide data bus and 24 bit wide data bus
And here's an open-source implementation I wrote a few years back. You can skip the part at the end that handles variable-length trailing bytes, since you have a fixed-width input.

Questions about lattice ecp5 fpga.
My SatCat5 project also has a few options. Anything under src/vhdl/common/cfgbus_* can be connected to AXI or Wishbone with a simple adapter.

GPSDO without VCXO?
For an all-digital solution, here's an NCO that generates an arbitrary-frequency square wave from a numeric counter.

Code coverage with clang and gcovr
Have a look here: https://github.com/philips-software/amp-embedded-infra-lib/blob/modern-cmake/cmake/emil_test_helpers.cmake where we use the EMIL_ENABLE_COVERAGE flag.

Looking for well written, modern C++ (17/20) example projects for microcontrollers
I can recommend having a look at: - https://github.com/philips-software/amp-embedded-infra-lib (stl-like replacement and utility library including a HAL definition - https://github.com/philips-software/amp-hal-st (HAL implementation for STs based on EMiL HAL) - https://github.com/philips-software/amp-preview (a GUI library for STs based on above mentioned repo's)

FreeRTOS-Cpp: C++17 header-only interface to the FreeRTOS kernel API
Not to downplay your work. But, we are in the process, almost finalised, tests and all of adding this kind of support as well. But then to allow freertos to work with c++'s native threading API. https://github.com/philips-software/amp-embedded-infra-lib/tree/feature/add-osal We have a thin wrapper, and during configuration you choose: None, native, freertos or zephyr.

What criteria do you use to choose super loop over RTOS
Everything that needs to do something is scheduled using a simple EventDispatcher.schedule(lambda) construction; adding the lambda to the event queue. If you want an example of such a system: https://github.com/philips-software/amp-embedded-infra-lib/blob/modern-cmake/infra/event/EventDispatcher.hpp

Looking for a GitHub repo which contains unit tests
You can have a look at https://github.com/philips-software/amp-embedded-infra-lib it is a library project. So not an actual embedded teacher. Although the library is aimed at embedded usage.

USB HID Device Configuration using nanopb and gRPC
https://github.com/philips-software/amp-embedded-infra-lib had support for RPC over protobuf.
- Looking for modern CMake tutorials or good open spurce examples
