> It appears unsuitable for use with DMA, which I use for all runtime IO The `embedded-hal-async` traits can be implemented with DMA, the Embassy HALs do so. This is a problem with the `nb` traits only. > The APIs tend to be a mess due to heavy use of typestates This is an issue of some HAL crates implementing the traits, not with the `embedded-hal` traits themselves. I also dislike the heavy use of typestates/generics, Embassy tries to implement the traits while keeping typestates at a minimum. (disclaimer: Embassy maintainer here)
