The idea behind OptionalPin has a few problems: - you need to impl the signal traits for NoPin which is a bit weird https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L413-L416 - you can pass any combination of set/unset pins, which needs checking at runtime https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L130 The replacement is to do multiple `new` constructors for each combination of pins you want to take.
