CANbussilla

CANbussilla is a fictional open-source software framework designed to simplify development and operation of CAN bus networks. It provides a cross-platform toolchain and API for interfacing with CAN hardware, capturing and transmitting messages, simulating CAN traffic, and collecting diagnostic data. The project emphasizes modularity, portability, and reproducibility in embedded and PC environments.

Architecture and features: The core consists of a hardware abstraction layer, a protocol layer implementing CAN 2.0A/B and CAN FD, and a set of utilities for logging, time stamping, and message filtering. It supports real-time capture with precise timestamps, software-based filters, and configurable bit rates. It includes a simulated bus mode (virtual CAN) for testing, and it can import database files (DBC, LDF) to translate numeric IDs into human-readable signals. APIs exist in C/C++ with bindings for Python and other languages.

Hardware support and integration: CANbussilla works with common CAN interfaces such as MCP2515 modules, USB-CAN adapters, PCIe CAN cards, and native MCU peripherals. It provides examples and drivers for popular platforms including Linux, Windows, and macOS, and can operate in standalone embedded environments or as a data-analysis backend on a desktop. It emphasizes portability and deterministic behavior where required.

Applications and reception: The software is used in automotive diagnostics, industrial automation, robotics, and education for teaching CAN concepts and for building test rigs. The project is community-driven, with permissive licensing and ongoing contributions from volunteers and vendors. Documentation covers installation, API usage, data formats, and debugging techniques.
