* feat: improve nrf54 support using new nrf-pacUlf Lilleengen2025-10-281-67/+95
| | | | | | | | | | | | | * Update nrf-pac to version that modifies nrf52 register layout to match nrf54 to reduce the amount of cfg needed for nrf54 support. * Make the following peripherals available on nrf54: twim, twis, spim, spis, uart, buffered uarte, dppi, gpiote, pwm, saadc * Add examples tested on the nrf54 dk Some code is based on or copied from other pull requests, modified to match the new nrf-pac layout.

* nrf: fix wrong order configuring gpios.Dario Nieuwenhuis2024-06-251-2/+3
| | | | | Docs say "PSEL.RXD, PSEL.RTS, PSEL.RTS, and PSEL.TXD must only be configured when the UARTE is disabled." For some reason nrf52 doesn't care but nrf91 does.

* embassy-nrf: Idle detection for RX only uarteTimo Kröger2023-06-131-44/+51
| | | | | Introduce `with_idle()` to upgrade an `UarteRx` instance to `UarteRxWithIdle`. Use the method in the split constructor aswell.
* Make interrupt module more standard.Dario Nieuwenhuis2023-06-081-11/+11
| | | | | | | | | | | | - 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.

* nrf/uart: do not error on zero length transfers.Dario Nieuwenhuis2022-12-151-10/+10
| | | | | | It's a perfectly fine thing to do, should be just a noop. Erroring is really annoying when you're writing a payload to uart that might be zero-length or not.

* Removes some of the code duplication for UarteWithIdlehuntc2022-10-091-267/+131
| | | | This commit removes some of the code duplication for UarteWithIdle at the expense of requiring a split. As the example illustrates though, this expense seems worth the benefit in terms of maintenance, and the avoidance of copying over methods. My main motivation for this commit was actually due to the `event_endtx` method not having been copied across.

|
* Do not use cfg_if for embedded-hal-async feature gates.Dario Nieuwenhuis2022-08-311-49/+50
| | | | Old code used `cfg_if!` because rustc still parses code inside disabled cfg's, and Rust stable at that time couldn't parse the new GAT where-clause location. This is not the case anymore.

* nrf/uart: add support for tx-only and rx-only uart.Dario Nieuwenhuis2022-06-251-27/+149
| | | | | Allow creating UarteRx/UarteTx directly. This allows using uart unidirectionally (rx-only or tx-only), without having to 'waste' a pin for the unused direction.
* Add more API docs for embassy-cortex-m and embassy-nrfUlf Lilleengen2022-06-231-3/+3
