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.

Polo 6r 2013 can hacking, any suggestion?
To see what is on the CAN bus, use the example program "CAN Receive" from here: https://github.com/coryjfowler/MCP_CAN_lib

Is my canbus hardware too slow to catch messages?
(2) Make sure the SPI clock frequency is at the maximum of 8Mhz (SPI.setClockDivider(2) = 8Mhz) (3) Use hardware filtering just for a single CAN bus ID, this reduces the I/O activity and allows the MCP2515 to just react to the data you need. (4) Try using this library & example https://github.com/coryjfowler/MCP_CAN_lib/blob/master/examples/CAN_receive/CAN_receive.ino

need help designing a system for a van
Can bus modules are easy to get and this library works well.

MCP2515 issues with GMLAN w/ Photos
try coreyjfowlers library with 500k can instead: https://github.com/coryjfowler/MCP_CAN_lib

Variable question
Could be either an enum or an int - check the header file in whichever CAN library you're using (apparently not this one or this one or this one - which one are you using?).
What are some alternatives?
arduino-esp32 - Arduino core for the ESP32
arduino-mcp2515 - Arduino MCP2515 CAN interface library
arduino-canhacker - CanHacker (lawicel) CAN adapter on Arduino + MCP2515
arduino-CAN - An Arduino library for sending and receiving data using CAN bus.
arduino-canbus-monitor - Can bus monitoring tool based on arduino and can bus shield. Implements CAN ASCII/SLCAN protocol compatible with Lawicel CAN232/CANUSB. Can be used for monitoring low speed CAN (interior can bus of most cars, less than 500kbps). For higher speeds serial port can become a bottleneck in case data density is high.
ArduinoJson - 📟 JSON library for Arduino and embedded C++. Simple and efficient.
arduino-MCP2515-nb - Arduino MCP2515 library, supporting non-blocking write operations.
