								 Dario Nieuwenhuis | 550da471be | stm32: Remove OptionalPin 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. | 2022-02-10 02:38:10 +01:00 |  |
