resolves #128

Please review diligently as I'm not overly familiar with this crate's code.

I stumbled across the same problem today and was quite pleased to this was already implemented. As a disclaimer: I got general embedded experience but in terms of idomatic rust I am quite a beginner. Still I reviewed your implementation and the tests. From my POV this looks good and I would have implemented it equally. Would like to see this upstream

I think this looks good, same kind of implementations as used in I2C.

Ok then all we need is @dbrgn to get some time and merge this.

It's been pending admin review for over half a year. I'm not holding my breathe. Instead, I've been using this from my fork's dev branch (cherry picked commits from this branch and another PR also pending review).

Yes I saw that.

Yeah, sorry, I haven't had the time to review so far. I will try again to get this project adopted by rust-embedded, in the hope that this will improve things.

@dbrgn thanks for your hard work, and thanks for adopting your baby. Hope we can gen some help from the @rust-embedded team now with the PRs. Please let us know if there is anything we can do to help.

I gotta say, I'm very glad someone is willing to carry this project forward! ❤️
