* hal-internal: remove impl DerefMut for PeripheralRef.Dario Nieuwenhuis2024-02-201-4/+4
| | | | | | | | | if you have `PeripheralRef<'a, AnyPIn>` for pin A, and `AnyPin` (owned) for pin B, you can `mem::swap` them. so, getting access forever to pin A, just by "sacrificing" pin B this defeats the point of PeripheralRef, which is if you got a `PeripheralRef<'a, T>` then you're only allowed to use the peripheral for `'a`. Also some drivers rely on the fact only one instance of a singleton exists for soundness, so this is a soundness fix for those.

| * Add a STM32/DMARingBuffer::read_exact helperAlex Ferro2023-07-221-3/+41
| | | | | | | | | | | | | | | | | | | | This provides a helper function with an async implementation, that will only return (or error) when it was able to read that many bytes, sleeping until ready. Additionally, corrected the documentation for Ringbuffer functions to use "elements" instead of "bytes" as the types were already generic over the word/element size.

* Make interrupt module more standard.Dario Nieuwenhuis2023-06-081-3/+3
| | | | | | | | | | | | - 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`.

* stm32: Refactor DMA interruptsGrant Miller2022-03-081-16/+20
| | | | | | | | Previously, every dma interrupt handler called the same `on_irq` function which had to check the state of every dma channel. Now, each dma interrupt handler only calls an `on_irq` method for its corresponding channel or channels.
* stm32: exclude spammy files from docs by prefixing with `_`.Dario Nieuwenhuis2022-03-041-2/+2
| | | | | | | These files end up containing chip-specific info, so they deduplicate really badly when building docs for all 1200 chips. The doc generator removes files starting with `_`.
