* Reset rx_started state of nrf buffered_uarte on initftilde2023-12-291-0/+1
| | | | | | This was likely forgotten as part of c46418f12. Without this, when creating a uarte instance, dropping it and then creating another instance, this instance would never receive any bytes.

* Make interrupt module more standard.Dario Nieuwenhuis2023-06-081-6/+5
| | | | | | | | | | | | - 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`.

| | | | | | | | | | | | | | | | | | | > dirbaio: so I was checking how zephyr does UARTE RX on nRF > dirbaio: because currently we have the ugly "restart DMA on line idle to flush it" hack > dirbaio: because according to the docs "For each byte received over the RXD line, an RXDRDY event will be generated. This event is likely to occur before the corresponding data has been transferred to Data RAM." > dirbaio: so as I understood it, the only way to guarantee the data is actually transferred to RAM is to stop+restart DMA > dirbaio: well, guess what? > dirbaio: they just count RXDRDY's, and process that amount of data without restarting DMA > dirbaio: with a timer configured as counter https://github.com/zephyrproject-rtos/zephyr/blob/main/drivers/serial/uart_nrfx_uarte.c#L650-L692 > dirbaio: 🤔🤷⁉️ > dirbaio: someone saying you can do the "hook up rxdrdy to a counter" trick, someone else saying it's wrong 🤪 https://devzone.nordicsemi.com/f/nordic-q-a/28420/uarte-in-circular-mode So we're going to do just that! - BufferedUarte is lock-free now. No PeripheralMutex. - The "restart DMA on line idle to flush it" hack is GONE. This means - It'll work correctly without RTS/CTS now. - It'll have better throughput when using RTS/CTS.

|\ | | | | | | | | | | | | | | 958: Implement proper `Drop` for `BufferedUarte` r=lulf a=ZoeyR The drop method in `BufferedUarte` was prone to hanging indefinitely and also didn't actually disable the peripheral. I mostly copied over the drop method from `Uarte` with some modifications since `BufferedUarte` could have a transmit lasting indefinitely. Co-authored-by: Zoey Riordan <[email protected]>

* common/PeripheralMutex: remove unsafe API. (#802)Dario Nieuwenhuis2022-06-091-16/+14

* Provides AsyncWrite with flushhuntc2021-12-101-0/+14
| | | | As per Tokio and others, this commit provides a `poll_flush` method on `AsyncWrite` so that a best-effort attempt at wakening once all bytes are flushed can be made.

| | | | Applies the Nordic workaround found in the `Uarte` for the nRF9160 and nRF5340 to the `BufferedUarte`.
* Rationale for uarte usagehuntc2021-12-011-0/+4
|
* Removed unsafe from uartehuntc2021-12-011-16/+17
| | | | The constructors themselves are not strictly unsafe. Interactions with DMA can be generally unsafe if a future is dropped, but that's a separate issue. It is important that we use the `unsafe` keyword diligently as it can lead to confusion otherwise.
