Hi @ryankurte! How does this compare to my v1.0.0-alpha.1 branch #144? Can we merge/split the effort? I mainly want to be compatible with 1.0.x for the development of #145, but have provided the changes in a separate branch if the repo wants them.

i somehow missed your PR when i made this one, they should be functionally equivalent. i haven't diffed em to check but, happy to close this in favour of yours and add the delta if there is anything missing.

[maxekman]

Sure, if that works for you @ryankurte. I'll see if I can finish it soon.

Do you think it could be useful to have a v1.0.0-dev branch for this repo so we can both merge any changes to it?

There is now some new info about how to support both 0.2.x and 1.0.0-alpha: https://github.com/rust-embedded/embedded-hal#adding-support-for-an-embedded-hal--alpha-version-in-a-hal-implementation

[ryankurte]

while it's possible to do this it's also pretty easy to build adaptors between versions, and to update things, so i definitely would not think it an expectation that both are supported.

Closed in favor of #388
