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.

-mfpu option unnecessary
You can see the startup assembly I use here: https://github.com/blippy/rpi/blob/master/stm32f411re/cmsis/01-blink/startup_stm32f411retx.s

Pico C programming without cMake, VS, etc
If you're happy about using the SDK, but don't want VS, then a simple template is here: https://github.com/blippy/rpi/tree/master/pico/0TEMPLATE
- Write to SD card in C++

SD/MMC reading/writing with C SDK
I have managed to interface to an SD card as a block device, no file system. I was able to play audio that I dumped to the card. The project is here: https://github.com/blippy/rpi/tree/master/pico/sdcard It is not feature-complete (it doesn't write to cards, and only supports version 2 cards), but hey, it is at least a proof-if-concept that it is doable.
- Look what I made: funky "bytebeat" music
- Drum sample player
- Button debouncer class

Best practices for embedded libraries / architecture overall
I am not sure if the above can be considered best practices but they were where I took the inspiration. I also tend to keep the driver API simple, usually consisting only of init, read, write, ioctl and close methods.
What are some alternatives?
