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.

Issues while connecting NeoPixel (WS2812B) LED strips with Raspberry Pi Pico
I'm having issues connecting the WS2812B with Raspberry Pi Pico. I'm trying to execute the example program https://github.com/JeremyGrosser/pico_examples/blob/master/ws2812_demo/src/main.adb
- What is the most low level way of setting GPIO outputs?

Designing Winterbloom's Castor & Pollux - a deep dive into the hardware design of a Roland Juno-inspired Eurorack module.
It'll all be open source eventually, but for now I've just released my driver libraries and some examples. https://github.com/JeremyGrosser/pico_examples

Programming the Raspberry Pi GPIO pins using Common Lisp?
I had a similar problem trying to use them using Ada. The solution that I found used the /sys filesystem (though u/excogitatio below says that that's deprecated). The specific paths that I found for the pins are in https://github.com/BrentSeidel/BBS-BBB-Ada/blob/master/src/bbs-embed-rpi.ads and how I used them is in https://github.com/BrentSeidel/BBS-BBB-Ada/blob/master/src/linux/bbs-embed-gpio-linux.adb. If you're willing to wade through Ada code, you may find other interesting things in that project.

December 2021 What Are You Working On?
I picked up a MCP4725 I2C DAC and an ADS1015 I2C ADC from AdaFruit and plan to write drivers for them for my personal driver library (as a side note, if anyone wants to move any of these to the Ada Driver Library, feel free). I am thinking of using these to add another module to my Raspberry Pi Mainframe Simulator so that I can have some knobs and a meter doing important looking things.
What are some alternatives?
