## Requirements & limits

- Needs the Linux SocketCAN subsystem and an appropriate CAN or virtual-CAN interface. The project documents native Linux and cross-compiled Android/Raspberry Pi builds using CMake.
- candump and cansniffer expose frames and changing bytes; they do not infer proprietary signal semantics. ISO-TP and J1939 commands additionally depend on the corresponding kernel support.
