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.

How to share data between cores on the STM32h745 using the Hardware Semaphore
Unfortunately, the data on the M7 side seems to repeat ever so often and I'm not sure why. A sample output is shown here. I'm not sure if I'm making a very obvious mistake here. I've looked around and tried all sorts of tricks. The only one that seems to have worked is Tijen Majerle's ring buffer implementation but this doesn't seem to make use of the HSEM. I'm looking for a HSEM solution partly out of curiosity and partly for performance reasons down the line.

How to implement bare metal C program to interface with multiple serial devices with minimal packet loss?
I suggest considering DMA as well. You can check this application note on using UART transfers (TX/RX) with DMA and interrupts.
