c924f89ead fix: add missing impl block for async qspi multiwrite 2024-01-03 13:08:53 +01:00

3916b26b25 Reset rx_started state of nrf buffered_uarte on init 
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.

9de08d56a0 nrf: spim: Anomaly 109 workaround for SPIM peripheral (#460) 
This implements SPIM TX workaround suggested from section 3.8.1
from Anomaly 109 addendum.

In workaround case we first keep track of original maxcnt values,
then initiate "fake" transfer with zero-length maxcnt values.
Once the "fake" transfer is triggered, we handle it, fill in the
original maxcnt values and restart the transmission.

921780e6bf Make interrupt module more standard. 
- 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`.

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.

ada3d5be7c nrf: rename UARTETWISPIn -> SERIALn 
The UARTETWISPIn naming is quite horrible. With the nRF53, Nordic realized this
and renamed the interrupts to SERIALn. Let's copy that for our peripheral names, in nrf53 and nrf91.

7fa478358a nrf: warn if uicr configuration could not be written. 
If the user requests some configuration, but UICR is already programmed
to something else, detect this and warn the user.

We don't do it for the debug port settings, because if they are wrong
then the user will simply not be able to read debug logs.

3f88bf6f9b nrf: add support for UICR configuration. 
- APPROTECT enable/disable. Notably this fixes issues with nrf52-rev3 and nrf53 from locking itself at reset.
- Use NFC pins as GPIO.
- Use RESET pin as GPIO.

NFC and RESET pins singletons are made available only when usable as GPIO,
for compile-time checking.

8497f98de2 Provides a means of obtaining the current WDT config 
Obtaining the current WDT config is important so that we do not have to duplication configuration around the place. A constructor method has been introduced that returns WDT config in accordance with how the register is presently configured. The bootloader example has also been updated to show the watchdog can be obtained and used.

bffa5be2f4 nrf/uart: do not error on zero length transfers. 
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.

1049: embassy-nrf: Add I2S module r=lulf a=chris-zen

This PR adds I2S support for the nrf52 series (`nrf52832`, `nrf52833`, `nrf52840`).

We could only test it in a `nrf52840` in master mode for an output stream (see `i2s_waveform` example), using a clone of the [Adafruit I2S Stereo Decoder - UDA1334A](https://learn.adafruit.com/adafruit-i2s-stereo-decoder-uda1334a/overview).

We were wondering if this could be a welcome addition to embassy, as we are working on this very informally and don't have much free time for it.
