Controller Area Network (CAN bus)

[reneherrero]

Is CAN bus communications something that is supported in rust on Cortex M? Any getting started tips/links?

All I'm finding in Google is based on Linux/SocketCAN. I can't imagine I'm the first to have this need?

Apologies if this is not the appropriate channel, I've recently fallen in love with Rust and am venturing into new territories... C is a dinosaur that needs to be turned into oil :)

The cortex-m crate only covers the Cortex-M core peripherals, while CAN peripherals would be vendor-specific. So you're asking in the wrong project :-)

embedded-hal provides an abstraction layer for vendor-specific peripherals. It doesn't support CAN as of yet, but there's been discussion and some stalled work: rust-embedded/embedded-hal#21, rust-embedded/embedded-hal#53, rust-embedded/embedded-hal#77

In addition, there might already be HAL APIs that support CAN for a specific chip. I can't think of any off the top of my head though, but maybe you can find something in the stm32-rs organization.

Thanks for the info @hannobraun, and apologies for the noise. Closing the issue.
