Show HN: Cantools – an extensive set of CAN bus tools
Has anyone taken canbus and deployed it on a greenfield non-automotive system? If so, what was the thought process to justify use of this protocol vs. something like ethernet? The selling point seems to be 'save copper' but the associated overheads (tooling, training, reduced throughput[0], larger connectors, multidrop bus debug drawbacks, etc.) seem like they would <i>far</i> outweigh any nominal savings in all but the highest volume production scenarios.<p>[0] <a href="https://en.wikipedia.org/wiki/ELM327#Protocols_supported_by_ELM327" rel="nofollow">https://en.wikipedia.org/wiki/ELM327#Protocols_supported_by_...</a>
