|\ \ \ | |/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 607: stm32: Add standard crate-wide macros for pin/dma traits r=Dirbaio a=Dirbaio All drivers will declare the traits using these macros. This has a few implications: - ALL drivers will have an Instance trait, even for drivers that usually have only one instance (for example crc, eth) - It's no longer possible to have a fn configure() in pin traits, drivers will have to do that some other way In the future, build.rs will generate all the impls instead of macrotables. Pin/Dma traits are no longer explicitly sealed, since gpio::Pin and dma::Channel are already sealed, which has the same effect. This means the `af_num()` and `request()` funcs are now public, but IMO that's okay, they're unlikely to change. Co-authored-by: Dario Nieuwenhuis <[email protected]>

* stm32: Remove OptionalPinDario Nieuwenhuis2022-02-106-37/+11
| | | | | | | | | The idea behind OptionalPin has a few problems: - you need to impl the signal traits for NoPin which is a bit weird https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L413-L416 - you can pass any combination of set/unset pins, which needs checking at runtime https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L130 The replacement is to do multiple `new` constructors for each combination of pins you want to take.
* Add embassy-bootUlf Lilleengen2022-02-097-0/+180
| | | | | | | | | | Embassy-boot is a simple bootloader that works together with an application to provide firmware update capabilities with a minimal risk. The bootloader consists of a platform-independent part, which implements the swap algorithm, and a platform-dependent part (currently only for nRF) that provides addition functionality such as watchdog timers softdevice support.

|\ | | | | | | | | | | | | | | | | | | | | | | 591: PWM WS2812B example and flexible sequence config r=Dirbaio a=huntc I've permitted the PWM sequences to be mutated on stopping the PWM by associating them with a new `SingleSequencer` structure. This is so that we can perform effects on the LEDs (and other use-cases, I'm sure!). The example has been updated to illustrate the use of this by flashing a WS2812B LED. There's also a `Sequencer` structure for more sophisticated PWM interactions, along with a `pwm_double_sequence` example to illustrate. These changes should make it possible to attain all of the nRF PWM functionality available. Co-authored-by: huntc <[email protected]>

| | | | | | | | 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.
