- Move typelevel interrupts to a special-purpose mod: `embassy_xx::interrupt::typelevel`.
- Reexport the PAC interrupt enum in `embassy_xx::interrupt`.
This has a few advantages:
- The `embassy_xx::interrupt` module is now more "standard".
- It works with `cortex-m` functions for manipulating interrupts, for example.
- It works with RTIC.
- the interrupt enum allows holding value that can be "any interrupt at runtime", this can't be done with typelevel irqs.
- When "const-generics on enums" is stable, we can remove the typelevel interrupts without disruptive changes to `embassy_xx::interrupt`.
doing this setup work repeatedly, on every wait, is unnecessary. with
nothing ever disabling the interrupt it is sufficient to enable it once
during device init and never touch it again.
InputFuture did not use and check edge interrupts correctly.
InterruptTrigger should've checked for not 1,2,3,4 but 1,2,4,8 since the
inte fields are bitmasks, and not clearing INTR would have repeatedly
triggered edge interrupts early.
A while ago `OutputOpenDrain` was made to implement `InputPin`,
something that allowed drivers for various one-wire protocols to be
written, but it's been lacking a `Wait` implementation — something
that's needed to write async versions of these drivers.
This commit also adds `get_level()` to `OutputOpenDrain`, since
`is_high()` and `is_low()` were already implemented, but `get_level()`
itself was missing.
When using gpio pin changes for things like peripheral interrupts these
debug! calls flood defmt, making it difficult to find what you're
actually looking for.
This commit adds the inline attribute to the recently added async gpio
functions. This is to enable cross-crate inlining and to be consistent
with the other functions implemented for Input and Flex.
- Move Interrupt and InterruptExecutor from `embassy` to `embassy-cortex-m`.
- Move Unborrow from `embassy` to `embassy-hal-common` (nothing in `embassy` requires it anymore)
- Move PeripheralMutex from `embassy-hal-common` to `embassy-cortex-m`.
