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.

CA, Bay Area Openpilot Verification on 2018 to 2020 Model Years
edit these files and try to keep KONA_EV in legacy https://github.com/commaai/panda/pull/904/commits/5518ffb6e39bc774e56dd571547141324c174fdc !<

Anyone know why the comma 3 has a blue blinky light on the front?
those are LEDs from the integrated Panda UNO board. they're to debug/signal Panda functionality https://github.com/commaai/panda/blob/master/docs/guide.pdf

Curated embedded code to learn from
Take a look at Panda module (https://github.com/commaai/panda), it a part of openpilot project. It is used to control your car over CAN bus.

Layout of Rust's u128 and i128 changed
I needed 128-bit and 256-bit integers on an embedded project recently.
In short, it was for fixed-point digital signal processing. The raw input and output samples were int64_t. We needed to add, subtract, multiply, and accumulate these to do filtering and linear regression with no loss of precision.
Conventional bigintegers weren't an option because the target application doesn't allow heap allocation. So we rolled our own [1] stack-allocated, fixed-width big integer class.

CRC32 algorithm match value between 96 bit wide data bus and 24 bit wide data bus
And here's an open-source implementation I wrote a few years back. You can skip the part at the end that handles variable-length trailing bytes, since you have a fixed-width input.

Questions about lattice ecp5 fpga.
My SatCat5 project also has a few options. Anything under src/vhdl/common/cfgbus_* can be connected to AXI or Wishbone with a simple adapter.
