method not found in `AtomicBool` #29

Closed pdgilbert closed 2 years ago

pdgilbert commented 2 years ago

(Related to #4 and #17.) Using shared-bus v0.2.0 I have several examples building on several device HALs but with stm32f0xx I have a problem with .compare_exchange. (Also happening with git shared-bus #0f429435.)

Compiling shared-bus v0.2.2 (https://github.com/Rahix/shared-bus#0f429435)
error[E0599]: no method named `compare_exchange` found for struct `AtomicBool` in the current scope

CI with examples working on other device HALs is at https://github.com/pdgilbert/rust-integration-testing/runs/4998981227?check_suite_focus=true. (stm32f030 is a job at the bottom.)

That's a thumbv6 platform, right? I think we need to use atomic-polyfill as a workaround...

pdgilbert commented 2 years ago

Yes, thumbv6m-none-eabi. I suppose I would have the same problem testing on stm32l0xx-hal but I have that disabled for other reasons.

Rahix commented 2 years ago

Do you want to look into integrating atomic-polyfill or should I take care of it?

pdgilbert commented 2 years ago

@Rahix could you please take care of it. (It is somewhat beyond my current state of understanding and I am already stretched pretty thin.)

Rahix commented 2 years ago

No problem, I'll do it.
