* feat: improve nrf54 support using new nrf-pacUlf Lilleengen2025-10-281-951/+0
| | | | | | | | | | | | | * 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.

| | | | | | | This change modifies UART initialization throughout Embassy to take pins before interrupts. Related to #1304.

| | | | | One possible future fix for this could be refactoring at least ppi arguments into separate struct.

* nrf: fix wrong order configuring gpios.Dario Nieuwenhuis2024-06-251-0/+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.

* 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]>
