Canadensis: A Cyphal implementation
This project implements (most of) Cyphal (previously called UAVCAN v1.0). As the Cyphal website explains, "Cyphal is an open technology for real-time intravehicular distributed computing and communication based on modern networking standards (Ethernet, CAN FD, etc.). It was created to address the challenge of on-board deterministic computing and data distribution in next-generation intelligent vehicles: manned and unmanned aircraft, spacecraft, robots, and cars."
This is currently an independent project, not affiliated with the Cyphal Consortium.
Submodule note
This repository uses a submodule for the public regulated data types.
When cloning, use git clone --recursive. If you have already cloned the repository without the
recursive option, run git submodule init followed by git submodule update. Otherwise, some tests will fail.

Other crates (canadensis_bit_length_set, canadensis_core, canadensis_derive_register_block,
canadensis_dsdl_frontend, canadensis_dsdl_parser, canadensis_encoding, and
canadensis_filter_config) are re-exported in various places, so you normally will not need to depend on them directly.
Status
This code is intended to conform to version 1.0-beta of the Cyphal specification.
Most of the functionality works. Some parts are incomplete:
- There are some tests, but there are probably several bugs in areas that have not been tested.
- The amount of dynamic memory allocation can be reduced, or at least documented better.
- It needs better documentation
Principles
- Runs on embedded devices
- Uses dynamic memory allocation, but only when necessary
- Supports Cyphal/CAN (classic CAN and CAN FD)
- Supports Cyphal/Serial and Cyphal/UDP (these transports are not fully specified yet, but the canadensis
implementations were compatible with
pycyphalwhen they were released)
