02:09 <re_irc> <@j​ohn_socha:m​atrix.org> I just noticed that `embedded_hal::digital::v2::InputPin` is marked as unproven, but `OutputPin` is not. Is there a reason for this difference?

06:48 <re_irc> <@e​ldruin:m​atrix.org> `InputPin` was not considered proven when it was first added to `embedded-hal`. It will be marked as proven in the next major release and can be considered proven now as well for all practical considerations.

07:12 <re_irc> <@e​ldruin:m​atrix.org> john_socha: I could not look much into detail but I would recommend you adding integration tests as well so that you can test what is actually sent over I2C. You can use `embedded-hal-mock` for that. Here [some examples](https://github.com/eldruin/lsm303agr-rs/blob/master/tests/integration.rs) that should not be...

07:39 <re_irc> <@h​enrik_alser:m​atrix.org> john_socha: Great job! 🙌 Some naming nits: consider prefixing your setter functions with ”set_” and maybe rename the functions that write to the display with ”write_” instead? As for the internal stuff, a more idiomatic way, that also provides a safe api would be to use enums (with value) instead...

Or if you wanna keep it as you have now with u8 at least semantically these functions should be marked as unsafe.
