6e7abba9ff nrf: rename Cargo feature references from "51" to "nrf51". 
Note: the feature doesn't actually exist, references are there just in case
nrf51xx is supported in the future.

cef6158c31 Extend SAADC one shot support 
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).

trait_alias seems unused. no idea why it's there.

d5ba35424d Replace PeripheralStateUnchecked with register_interrupt_unchecked 2021-07-29 15:11:26 +10:00
Liam Murphy
079526559f Remove critical sections from PeripheralMutex interrupt handler by 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.

744e2cbb8a extras: Fix UB in Peripheral 
`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.
