Yes, I love ST reference manuals. Sometimes it's easier to poke registers directly using the definitions in the CMSIS headers when you're doing something more complicated with the ST reference manual as your reference. The layer of indirection introduced by a HAL makes working off the ref manual more difficult, and sometimes impossible without poking at least a couple of registers directly. Typically I'd do that as a first cut, and look to add some abstraction once it's already working. I haven't gone down the Rust rabbit hole so far, mostly due to lack of time. Hopefully the embedded support will have matured nicely by the time I do. I see there are a couple of viable looking RTOSs making good progress.
