Announcing canadensis (another Rust implementation of UAVCAN v1)

I recently released version 0.2 of canadensis, which implements UAVCAN v1 in Rust. This version fixes many of the limitations and inconvenient aspects of the previous version.

Major new features in version 0.2 include:

  • A pure-Rust DSDL parser and code generator that produces Rust data types and serialization/deserialization code
    • A procedural macro that you can put in your Rust code to generate code from data types as part of the normal build process
  • Experimental UAVCAN/UDP and UAVCAN/Serial transports (these transports are not yet fully specified, but the canadensis implementations are compatible with pyuavcan)

The core functionality, UAVCAN/CAN transport, and UAVCAN/Serial transport work on microcontrollers with #![no_std], although they do use dynamic memory allocation. All functions that allocate memory return errors if memory allocation fails, instead of aborting or calling the global allocation error handler.

The UAVCAN/CAN transport is reasonably stable, and I have been using it successfully on some microcontrollers communicating over classic CAN.

There are some examples that run on Linux to show some ways to use different parts of canadensis.

Like all non-trivial software, canadensis contains bugs. Issues and pull requests are welcome in the canadensis repository.
