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.

Beginner issues using ButterStick dev board
The overview says the onboard oscillator is 60 MHz. But, the schematic says it's 30 MHz (visible on page 6), which I confirmed with a blinking LED timing test. Can I configure its speed somehow? I read that a PLL can multiply the frequency, but I don't know how those work or how to configure or implement one, and I wasn't expecting to need to when I read that the clock is 60 MHz. I thought that maybe I can trigger on both clock edges, but I read that that doesn't work without special support from the FPGA, and mine doesn't have it (or the compiler doesn't).
What are some alternatives?
