Easily build and control CANOpen nodes in Rust.

Zencan's goal is to enable rapid creation of a CANOpen node in a no_std embedded context using a TOML configuration file and code generation. It also provides utilities for communicating with the nodes from a linux environment.

This project is still in the prototype stage, so it's lacking some features and may yet go through a lot of API churn.

• zencan-node: Implements a zencan node. no_std compatible.
• zencan-build: Code generation for generating the static data associated with a node, based on a device config TOML file.
• zencan-client: Client library for communicating with nodes
• zencan-cli: Command line tools for interacting with devices
• zencan-common: Shared library used by both node and client

I like CAN, and I wanted to make it easy to build devices with lots of communication features in Rust -- mostly so I would use that, instead of like, hard-coding that one CAN message I need my device to send.

• Support embedded targets with no_std/no_alloc with statically allocated object storage
• Support enumeration of devices on a bus
• Support software version reporting and bootloading over the bus
• Support CAN-FD
• Support bulk data transfer
• Generate EDS and DBC files for integration into existing tools
• Support persistence of configuration to flash via application provided callbacks
