* | Extend SAADC one shot supporthuntc2021-10-091-39/+136
|/ | | | | | | | One-shot mode now permits the sampling of differential pins, and the sampling of multiple pins simultaneously. A new ChannelConfig structure has been introduced so that multiple channels can be configured individually. Further, the `sample` method now accepts a buffer into which samples are written. Along the way, I've reset some default configuration to align with Nordic's settings in their nrfx saadc driver. Specifically, the channel gain defaults to 6 (from 4) and the time defaults to 10us (from 20us).

| * Remove critical sections from `PeripheralMutex` interrupt handler by ↵Liam Murphy2021-07-271-9/+11
| | | | | | | | | | | | | | | | checking the interrupt's priority on startup. Since `PeripheralMutex` is the only way to safely maintain state across interrupts, and it no longer allows setting the interrupt's priority, the priority changing isn't a concern. This also prevents other causes of UB due to the interrupt being exposed during `with`, and allowing enabling the interrupt and setting its context to a bogus pointer.

| * extras: Fix UB in `Peripheral`Liam Murphy2021-07-051-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `Peripheral` assumed that interrupts can't be preempted, when they can be preempted by higher priority interrupts. So I put the interrupt handler inside a critical section, and also added checks for whether the state had been dropped before the critical section was entered. I also added a `'static` bound to `PeripheralState`, since `Pin` only guarantees that the memory it directly references will not be invalidated. It doesn't guarantee that memory its pointee references also won't be invalidated. There were already some implementations of `PeripheralState` that weren't `'static`, though, so I added an unsafe `PeripheralStateUnchecked` trait and forwarded the `unsafe` to the constructors of the implementors.
