* | Improve nRF Saadc samplinghuntc2022-03-071-7/+76
| | | | | | | | | | | | | | | | | | | | Starting the sampling task prior to starting the SAADC peripheral can lead to unexpected buffer behaviour with multiple channels. We now provide an init callback at the point where the SAADC has started for the first time. This callback can be used to kick off sampling via PPI. We also need to trigger the SAADC to start sampling the next buffer when the previous one is ended so that we do not drop samples - the major benefit of double buffering. As a bonus we provide a calibrate method as it is recommended to use before starting up the sampling. The example has been updated to illustrate these new features.

|\ \ | |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | 613: Rust stable support r=Dirbaio a=Dirbaio This PR adds (limited) stable Rust support! The drawbacks are: - No `#[embassy::task]`, `#[embassy::main]`. (requires `type_alias_impl_trait`). You have to manually allocate the tasks somewhere they'll live forever. See [example](https://github.com/embassy-rs/embassy/blob/master/examples/nrf/src/bin/raw_spawn.rs) - No async trait impls (requires GATs). Note that the full API surface of HALs is still available through inherent methods: #552 #581 - Some stuff is not constructible in const (requires `const_fn_trait_bound`), although there's an (ugly) workaround for the generic `Mutex`. So it's not that bad in the end, it's fully usable for shipping production-ready firmwares. We'll still recommend nightly as the default, until GATs and `type_alias_impl_trait` are stable.

* Own the sequence bufferhuntc2022-01-291-32/+76
| | | | This approach owns the sequence buffers which, while introducing an extra move, it eliminates the need to guard the lifetime of the sequence buffer. Given ownership, the buffer will be retained until the PWM sequence task is stopped.

* Stop PWM before assigning the new sequencehuntc2022-01-251-2/+2
| | | | | | I had introduced a small bug in my last PR where I assigned the sequence before stopping the PWM. I now stop the PWM before doing that now. Also, corrected a math comment.
* Strengthen the borrowhuntc2022-01-241-1/+1
| | | | The start method is now safe. Because it has the potential of borrowing the sequence and mutating itself, the sequence must outlive the Pwm struct.
* Permit many sequences to be passedhuntc2022-01-231-30/+32
| | | | Sequences are now passed in via the start method to avoid having to stop the PWM and restart it. Sequences continue to be constrained with the same lifetime of the Pwm object itself. The pwm_sequence example has been extended to illustrate multiple sequences being passed around.
