34a8a64bf5 stm32: make tick rate configurable 
The stm32 time drivers support arbitrary tick rates but the associated
Cargo features do not. Enabling any time driver presently enables
`embassy/time-tick-32768hz`; instead, enable only `embassy/time`.

This is a breaking change: users must now choose a tick rate. The
previous behavior is available by enabling the
`embassy/time-tick-32768hz` feature, but now users may also choose
`embassy/time-tick-1000hz` or `embassy/time-tick-1mhz` instead.

781:  embassy-net v2 r=Dirbaio a=Dirbaio

- No more `dyn`
- It's no longer a global singleton, you can create muliple net stacks at once.
  - You can't tear them down though, the Device it still has to be `'static` due to restrictions with smoltcp's "fake GAT" in the Device trait. :(
- Removed `_embassy_rand` hack, random seed is passed on creation.



785: stm32: g0: add PLL clock source r=Dirbaio a=willglynn

STM32G0 SYSCLK can be sourced from PLLRCLK. Given that the HSI runs at 16 MHz and the HSE range is 4-48 MHz, the PLL is the only way to reach 64 MHz. This commit adds `ClockSrc::PLL`.

The PLL sources from either HSI16 or HSE, divides it by `m`, and locks its VCO to multiple `n`. It then divides the VCO by `r`, `p`, and `q` to produce up to three associated clock signals:

  * PLLRCLK is one of the inputs on the SYSCLK mux. This is the main reason the user will configure the PLL, so `r` is mandatory and the output is enabled unconditionally.
  * PLLPCLK is available as a clock source for the ADC and I2S peripherals, so `p` is optional and the output is conditional.
  * PLLQCLK exists only on STM32G0B0xx, and exists only to feed the MCO and MCO2 peripherals, so `q` is optional and the output is conditional.

When the user specifies `ClockSrc::PLL(PllConfig)`, `rcc::init()` calls `PllConfig::init()` which initializes the PLL per [RM0454]. It disables the PLL, waits for it to stop, enables the source oscillator, configures the PLL, waits for it to lock, and then enables the appropriate outputs. `rcc::init()` then switches the clock source to PLLRCLK.

`rcc::init()` is now also resonsible for calculating and setting flash wait states. SYSCLCK < 24 MHz is fine in the reset state, but 24-48 MHz requires waiting 1 cycle and 48-64 MHz requires waiting 2 cycles. (This was likely a blocker for anyone using HSE >= 24 MHz, with or without the PLL.) Flash accesses are now automatically slowed down as needed before changing the clock source, and sped up as permitted after changing the clock source. The number of flash wait states also determines if flash prefetching will be profitable, so that is now handled automatically too.

fc32b3750c Remove embassy_hal_common::usb. 
The replacement is `embassy-usb`. There's a WIP driver for stm32 USBD in #709,
there's no WIP driver for stm32 USB_OTG. This means we're left without
USB_OTG support for now.

Reason for removing is I'm going to soon remove `embassy::io`, and
USB uses it. I don't want to spend time maintaining "dead" code
that is going to be removed. Volunteers welcome, either to update
old USB to the new IO, or write a USB_OTG driver fo the new USB.

743: Add PLL config support for F2 r=Dirbaio a=Gekkio

- minor changes to make the F2 RCC API a bit more flexible
- low-level PLL config with assertions based on datasheet specs. It shouldn't be very difficult to later add a "reverse API" where you pass the clocks you want to a function and it generates a `PLLConfig` struct for you
- PLL API tested on my custom board with 12 MHz HSE as source for PLL to generate max clocks for SYSCLK/AHB/APB/APB1/PLL48
- the example *should* work but is untested since I don't have the Nucleo board 😞

SMI Ethernet PHYs all share a common base set of registers that can do
90% of all tasks. The LAN8742 driver used some vendor-specific
registers to check link negotiation status, but the need for that was
debatable, so I migrated it to a generic driver instead, anybody who
wants extra functionality can copy it and impl their own on top of it.

669: Add SDMMC v1 and SDIO support r=Dirbaio a=chemicstry

SDMMC v2 peripheral is an extension of SDMMC v1 (or SDIO) so I managed to reuse most of the code, with some cfg's.

Apart from small differeces in registers, the biggest change is that v2 uses internal DMA, while v1 has to use shared DMA peripheral. This makes code a bit uglier, because DMA channel for v1 has to be passed around. Not sure if it's possible to make it any cleaner.

This also adds `TransferOptions` structure to DMA, because SDMMC v1 requires setting peripheral flow control and burst transfers. Let me know if some alternative way would be prefered.

I tested this on STM32F429ZIT6 (with sd card) and STM32H745ZIT6 (with oscilloscope).

Depends on: https://github.com/embassy-rs/stm32-data/pull/130

Now, each dma interrupt handler only calls an `on_irq` method for its
corresponding channel or channels.

652: Use new stm32-data registers and fix AHB clock calculation r=Dirbaio a=msamsonoff

This is the follow-on to my PR against stm32-data that added new register enums for the G0. I have updated the G0 RCC module to use those new enums.

I have also fixed an issue with the calculation of the AHB clock rate. 32 is not available as an AHB prescaler. The sequence jumps from 16 to 64. The original bit shifting math did not account for this gap. I have replaced it with a `match` instead.

* Multiple error flags can be set at the same time:
  Handle them all in one go intstead of re-entering the ISR for each one so that
  we do not lose any error flags on v1 hardware.
* Wake when the RX buffer becomes full: This allows fast running chips to pull data
  from the buffer before receiving the next byte.

550da471be stm32: Remove OptionalPin 
The idea behind OptionalPin has a few problems:

- you need to impl the signal traits for NoPin which is a bit weird https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L413-L416
- you can pass any combination of set/unset pins, which needs checking at runtime  https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L130

The replacement is to do multiple `new` constructors for each combination of pins you want to take.

601: [part 1/n] Change macrotables to build.rs codegen r=lulf a=Dirbaio

This PR replaces the "macrotables" (the macros like `stm32_data::peripherals!`) with a `const METADATA`.

Macrotables had some problems:

- Hard to debug
- Somewhat footgunny (typo the "pattern" and then nothing matches and the macro now expands to nothing, silently!)
- Limited power
  - Can't count, so we had to add a [special macrotable for that](f50f3f0a73/embassy-stm32/src/dma/bdma.rs (L26)).
  - Can't remove duplicates, so we had to fallback to [Rust code in build.rs](f50f3f0a73/embassy-stm32/build.rs (L105-L145))
  - Can't include the results as a listto another macro, so again [build.rs](https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/build.rs#L100-L101).

They work fine for the 95% of cases, but for the remaining 5% we need Rust code in build.rs. So we might as well do everything with Rust code, so everything is consistent.

The new approach generates a `const METADATA: Metadata = Metadata { ... }` with [these structs](https://github.com/embassy-rs/embassy/blob/unmacrotablize/stm32-metapac-gen/src/assets/metadata.rs) in `stm32-metapac`. `build.rs` can then read that and generate whatever code.

6179da6b9c stm32/dma: eagerly start transfers when calling the functions. 
`async fn`s do nothing until polled, but we want the DMA transfer to
immediately start in this case. Drivers rely on it. Some require special
orders, such as "start DMA, start SPI, then wait for DMA" which is awkward
to do without eager start.

Also use a manually-impl'd future, this allows getting rid of the "double"
Unborrow channel clone.

482: Add MCO peripheral. r=Dirbaio a=matoushybl

This PR adds an abstraction over STM32 RCC feature called MCO (Microcontroller Clock Output). The clock output can bind to several clock sources and then can be scaled using a prescaler.

Given that from the embassy ecosystem the RCC is generaly invisible to the user, the MCO was implemented as a separate peripheral bound to the pin where the clock should appear.

STM32H7: Ethernet: Disable RA in MAC filtering, fix order of MACA0 register writes. 2021-09-06 23:16:43 +01:00
Bob McWhirter
d4bf78a0c1 Don't set SAF=true, do set RA=true for Ethernet. 
Source-Address-Filtering is not helping the board to receive packets.
For unknown reasons, the Receive-All is required, when in theory

7ad6280e65 Add HAL for SubGhz peripheral for STM32 WL series 
Based on the HAL from stm32wl, the peripheral driver has been
modified to fit into embassy, using the embassy APIs, providing
operation of the radio peripheral.

The initial version does not offer any async APIs, but the example
shows how the radio IRQ can be used to perform async TX of the radio.

Older families like F1 and F4 have a consistent naming for the CAN
peripherals: CAN when there is only one instance, CAN1/CAN2/CAN2 if
there are multiple instances.
Newer families like L4 and F7 use the name CAN1 even if there is only
one instance. The number of filter banks is incorrect for those.

079526559f Remove critical sections from PeripheralMutex interrupt handler by checking the interrupt's priority on startup. 
Since `PeripheralMutex` is the only way to safely maintain state across interrupts, and it no longer allows setting the interrupt's priority, the priority changing isn't a concern.

This also prevents other causes of UB due to the interrupt being exposed during `with`, and allowing enabling the interrupt and setting its context to a bogus pointer.
