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.

I finally understand enough about programming to make this simple little 3d starfield running on just an arduino
Using the lcdgfx library to handle the lowest level stuff. Implemented basic 'real 3D' rendering from this example from a buddy (for Pico8). The 3d projection math was a lot simpler than I thought it would be!

Can't read registers of PN532
I glanced thru the library and see if the rx buffer size is set too low, it will return 0 from your call, looking like it got nothing back. I think you may need to call setRxBuffer() and setTxBuffer. See here
- I think I use all usable GPIO pins. GPIO 0 is strapping pin. GPIO 34 & 35 are input only. I need to remove GPIO 2 temporary during firmware upload but it works fine.
What are some alternatives?
