Simplify parallel GPIO interface and add new error variant #13

Closed andresovela closed 3 years ago

andresovela commented 3 years ago

I simplified the API for the parallel GPIO interface by grouping the bus into an array of pins rather than 8 individual pins. This allows to further simplify the set_value() function.

I also added a new variant to the DisplayError enum to represent issues that arise while asserting or de-asserting the reset pin. That is not used in these crates, but it is a useful error to have for consumers of this library.

I split this PR into #14, #15 and #16. I didn't bump the crate's version this time. I'll leave it to you for when you want to make another release.
