# cyw43-pio
|
||||
|
||||
RP2040 PIO driver for the nonstandard half-duplex SPI used in the Pico W. The PIO driver offloads SPI communication with the WiFi chip and improves throughput.
|
||||
|
||||
## Minimum supported Rust version (MSRV)
|
||||
|
||||
Embassy is guaranteed to compile on the latest stable Rust version at the time of release. It might compile with older versions but that may change in any new patch release.

= Best Practices
|
||||
|
||||
Over time, a couple of best practices have emerged. The following list should serve as a guideline for developers writing embedded software in _Rust_, especially in the context of the _Embassy_ framework.
|
||||
|
||||
== Passing Buffers by Reference
|
||||
It may be tempting to pass arrays or wrappers, like link:https://docs.rs/heapless/latest/heapless/[`heapless::Vec`], to a function or return one just like you would with a `std::Vec`. However, in most embedded applications you don't want to spend ressources on an allocator and end up placing buffers on the stack.
|
||||
This, however, can easily blow up your stack if you are not careful.
|
||||
|
||||
Consider the following example:
|
||||
[,rust]
|
||||
----
|
||||
fn process_buffer(mut buf: [u8; 1024]) -> [u8; 1024] {
|
||||
// do stuff and return new buffer
|
||||
for elem in buf.iter_mut() {
|
||||
*elem = 0;
|
||||
}
|
||||
buf
|
||||
}
|
||||
|
||||
pub fn main() -> () {
|
||||
let buf = [1u8; 1024];
|
||||
let buf_new = process_buffer(buf);
|
||||
// do stuff with buf_new
|
||||
()
|
||||
}
|
||||
----
|
||||
When calling `process_buffer` in your program, a copy of the buffer you pass to the function will be created,
|
||||
consuming another 1024 bytes.
|
||||
After the processing, another 1024 byte buffer will be placed on the stack to be returned to the caller.
|
||||
(You can check the assembly, there will be two memcopy operations, e.g., `bl __aeabi_memcpy` when compiling for a Cortex-M processor.)
|
||||
|
||||
*Possible Solution:*
|
||||
|
||||
Pass the data by reference and not by value on both, the way in and the way out.
|
||||
For example, you could return a slice of the input buffer as the output.
|
||||
Requiring the lifetime of the input slice and the output slice to be the same, the memory safetly of this procedure will be enforced by the compiler.
|
||||
|
||||
[,rust]
|
||||
----
|
||||
fn process_buffer<'a>(buf: &'a mut [u8]) -> &'a mut[u8] {
|
||||
for elem in buf.iter_mut() {
|
||||
*elem = 0;
|
||||
}
|
||||
buf
|
||||
}
|
||||
|
||||
pub fn main() -> () {
|
||||
let mut buf = [1u8; 1024];
|
||||
let buf_new = process_buffer(&mut buf);
|
||||
// do stuff with buf_new
|
||||
()
|
||||
}

@ -45,8 +45,6 @@ The BOOTLOADER_STATE partition must be big enough to store one word per page in
|
||||
|
||||
The bootloader has a platform-agnostic part, which implements the power fail safe swapping algorithm given the boundaries set by the partitions. The platform-specific part is a minimal shim that provides additional functionality such as watchdogs or supporting the nRF52 softdevice.
|
||||
|
||||
NOTE: The linker scripts for the application and bootloader look similar, but the FLASH region must point to the BOOTLOADER partition for the bootloader, and the ACTIVE partition for the application.
|
||||
|
||||
=== FirmwareUpdater
|
||||
|
||||
The `FirmwareUpdater` is an object for conveniently flashing firmware to the DFU partition and subsequently marking it as being ready for swapping with the active partition on the next reset. Its principle methods are `write_firmware`, which is called once per the size of the flash "write block" (typically 4KiB), and `mark_updated`, which is the final call.

= Delaying a Task
|
||||
|
||||
In an embedded program, delaying a task is one of the most common actions taken. In an event loop, delays will need to be inserted to ensure
|
||||
that other tasks have a chance to run before the next iteration of the loop is called, if no other I/O is performed. Embassy provides an abstraction
|
||||
to delay the current task for a specified interval of time.
|
||||
|
||||
Timing is serviced by the `embassy::time::Timer` struct, which provides two timing methods.
|
||||
|
||||
`Timer::at` creates a future that completes at the specified `Instant`, relative to the system boot time.
|
||||
`Timer::after` creates a future that completes after the specified `Duration`, relative to when the future was created.
|
||||
|
||||
An example of a delay is provided as follows:
|
||||
|
||||
[,rust]
|
||||
----
|
||||
use embassy::executor::{task, Executor};

||||

||||
// async sleep primitive, suspends the task for 500ms.

||||
Timer::after(Duration::from_millis(500)).await;

You are likely missing some features of the `embassy-executor` crate.
|
||||
|
||||
For Cortex-M targets, consider making sure that ALL of the following features are active in your `Cargo.toml` for the `embassy-executor` crate:
|
||||
|
||||
* `arch-cortex-m`
|
||||
* `executor-thread`
|
||||
* `nightly`
|
||||
|
||||
For ESP32, consider using the executors and `#[main]` macro provided by your appropriate link:https://crates.io/crates/esp-hal-common[HAL crate].

== Why is my binary so big?
|
||||
|
||||
The first step to managing your binary size is to set up your link:https://doc.rust-lang.org/cargo/reference/profiles.html[profiles].
|
||||
|
||||
[source,toml]
|
||||
----
|
||||
[profile.release]
|
||||
debug = false
|
||||
lto = true
|
||||
opt-level = "s"
|
||||
incremental = false
|
||||
codegen-units = 1
|
||||
----
|
||||
|
||||
All of these flags are elaborated on in the Rust Book page linked above.
|
||||
|
||||
=== My binary is still big... filled with `std::fmt` stuff!
|
||||
|
||||
This means your code is sufficiently complex that `panic!` invocation's formatting requirements could not be optimized out, despite your usage of `panic-halt` or `panic-reset`.
|
||||
|
||||
You can remedy this by adding the following to your `.cargo/config.toml`:
|
||||
|
||||
[source,toml]
|
||||
----
|
||||
[unstable]
|
||||
build-std = ["core"]
|
||||
build-std-features = ["panic_immediate_abort"]
|
||||
----
|
||||
|
||||
This replaces all panics with a `UDF` (undefined) instruction.
|
||||
|
||||
Depending on your chipset, this will exhibit different behavior.
|
||||
|
||||
Refer to the spec for your chipset, but for `thumbv6m`, it results in a hardfault. Which can be configured like so:
|
||||
|
||||
[source,rust]
|
||||
----
|
||||
#[exception]
|
||||
unsafe fn HardFault(_frame: &ExceptionFrame) -> ! {
|
||||
SCB::sys_reset() // <- you could do something other than reset
|
||||
}
|
||||

== Error: `Only one package in the dependency graph may specify the same links value.`
|

|

You have multiple versions of the same crate in your dependency tree. This means that some of your
|
||||
embassy crates are coming from crates.io, and some from git, each of them pulling in a different set
|
||||
of dependencies.
|
||||
|
||||
To resolve this issue, make sure to only use a single source for all your embassy crates! To do this,
|
||||
you should patch your dependencies to use git sources using `[patch.crates.io]` and maybe `[patch.'https://github.com/embassy-rs/embassy.git']`.

||||
|
||||

== How can I optimize the speed of my embassy-stm32 program?
|
||||
|
||||
* Make sure RCC is set up to go as fast as possible
|
||||
* Make sure link:https://docs.rs/cortex-m/latest/cortex_m/peripheral/struct.SCB.html[flash cache] is enabled
|
||||
* build with `--release`
|
||||
* Set the following keys for the release profile in your `Cargo.toml`:
|
||||
** `opt-level = "s"`
|
||||
** `lto = "fat"`
|
||||
* Set the following keys in the `[unstable]` section of your `.cargo/config.toml`
|
||||
** `build-std = ["core"]`
|
||||
** `build-std-features = ["panic_immediate_abort"]`
|
||||
* Enable feature `embassy-time/generic-queue`, disable feature `embassy-executor/integrated-timers`
|
||||
* When using `InterruptExecutor`:
|
||||
** disable `executor-thread`
|
||||
** make `main`` spawn everything, then enable link:https://docs.rs/cortex-m/latest/cortex_m/peripheral/struct.SCB.html#method.set_sleeponexit[SCB.SLEEPONEXIT] and `loop { cortex_m::asm::wfi() }`
|
||||
** *Note:* If you need 2 priority levels, using 2 interrupt executors is better than 1 thread executor + 1 interrupt executor.

== What is async?
|

When handling I/O, software must call functions that block program execution until the I/O operation completes. When running inside of an OS such as Linux, such functions generally transfer control to the kernel so that another task (known as a “thread”) can be executed if available, or the CPU can be put to sleep until another task is ready.

When running inside of an OS such as Linux, such functions generally transfer control to the kernel so that another task, known as a thread, can be executed if available, or the CPU can be put to sleep until another such task is ready to perform more work. Because an OS cannot presume that threads will behave cooperatively, threads are relatively resource-intensive, and may be forcibly interrupted they do not transfer control back to the kernel within an allotted time. But if tasks could be presumed to behave cooperatively, or at least not maliciously, it would be possible to create tasks that appear to be almost free when compared to a traditional OS thread. In Rust, these lightweight tasks, known as 'coroutines' or 'goroutines' in other languages, are implemented with async.

In other programming languages, these lightweight tasks are known as “coroutines” or ”goroutines”. In Rust, they are implemented with async. Async-await works by transforming each async function into an object called a future. When a future blocks on I/O the future yields, and the scheduler, called an executor, can select a different future to execute.
|
||||
|
||||
Compared to alternatives such as an RTOS, async can yield better performance and lower power consumption because the executor doesn't have to guess when a future is ready to execute. However, program size may be higher than other alternatives, which may be a problem for certain space-constrained devices with very low memory. On the devices Embassy supports, such as stm32 and nrf, memory is generally large enough to accommodate the modestly-increased program size.

== What is Embassy?
|
||||
|
||||
The Embassy project consists of several crates that you can use together or independently:
|
||||
|
||||
=== Executor
|
||||
The link:https://docs.embassy.dev/embassy-executor/[embassy-executor] is an async/await executor that generally executes a fixed number of tasks, allocated at startup, though more can be added later. The executor may also provide a system timer that you can use for both async and blocking delays. For less than one microsecond, blocking delays should be used because the cost of context-switching is too high and the executor will be unable to provide accurate timing.
|
||||
|
||||
=== Hardware Abstraction Layers
|
||||
HALs implement safe Rust API which let you use peripherals such as USART, UART, I2C, SPI, CAN, and USB without having to directly manipulate registers.
|
||||
|
||||
Embassy provides implementations of both async and blocking APIs where it makes sense. DMA (Direct Memory Access) is an example where async is a good fit, whereas GPIO states are a better fit for a blocking API.
|
||||
|
||||
The Embassy project maintains HALs for select hardware, but you can still use HALs from other projects with Embassy.

||||

||||

For less than one microsecond, blocking delays should be used because the cost of context-switching is too high and the executor will be unable to provide accurate timing.
|
||||

|
||||
NOTE: A common question is if one can use the Embassy HALs standalone. Yes, it is possible! There are no dependency on the executor within the HALs. You can even use them without async,
|
||||
as they implement both the link:https://github.com/rust-embedded/embedded-hal[Embedded HAL] blocking and async traits.

||||
|
||||
=== Networking
|
||||
The link:https://docs.embassy.dev/embassy-net/[embassy-net] network stack implements extensive networking functionality, including Ethernet, IP, TCP, UDP, ICMP and DHCP. Async drastically simplifies managing timeouts and serving multiple connections concurrently. Several drivers for WiFi and Ethernet chips can be found.

|
||||
=== Bootloader and DFU
|
||||
link:https://github.com/embassy-rs/embassy/tree/master/embassy-boot[embassy-boot] is a lightweight bootloader supporting firmware application upgrades in a power-fail-safe way, with trial boots and rollbacks.
|
||||
|
||||
== What is DMA?
|
||||
|
||||
For most I/O in embedded devices, the peripheral doesn't directly support the transmission of multiple bits at once, with CAN being a notable exception. Instead, the MCU must write each byte, one at a time, and then wait until the peripheral is ready to send the next. For high I/O rates, this can pose a problem if the MCU must devote an increasing portion of its time handling each byte. The solution to this problem is to use the Direct Memory Access controller.
|
||||
|
||||
The Direct Memory Access controller (DMA) is a controller that is present in MCUs that Embassy supports, including stm32 and nrf. The DMA allows the MCU to set up a transfer, either send or receive, and then wait for the transfer to complete. With DMA, once started, no MCU intervention is required until the transfer is complete, meaning that the MCU can perform other computation, or set up other I/O while the transfer is in progress. For high I/O rates, DMA can cut the time that the MCU spends handling I/O by over half. However, because DMA is more complex to set-up, it is less widely used in the embedded community. Embassy aims to change that by making DMA the first choice rather than the last. Using Embassy, there's no additional tuning required once I/O rates increase because your application is already set-up to handle them.

= Starting a new Embassy project
|
||||
|
||||
Once you’ve successfully xref:getting_started.adoc[run some example projects], the next step is to make a standalone Embassy project. The easiest way to do this is to adapt an example for a similar chip to the one you’re targeting.
|
||||
|
||||
As an example, let’s create a new embassy project from scratch for a STM32G474. The same instructions are applicable for any supported chip with some minor changes.
|
||||
|
||||
Run:
|
||||
|
||||
[source,bash]
|
||||
----
|
||||
cargo new stm32g474-example
|
||||
cd stm32g474-example
|
||||
----
|
||||
|
||||
to create an empty rust project:
|
||||
|
||||
[source]
|
||||
----
|
||||
stm32g474-example
|
||||
├── Cargo.toml
|
||||
└── src
|
||||
└── main.rs
|
||||
----
|
||||
|
||||
Looking in link:https://github.com/embassy-rs/embassy/tree/main/examples[the Embassy examples], we can see there’s a `stm32g4` folder. Find `src/blinky.rs` and copy its contents into our `src/main.rs`.
|
||||
|
||||
== .cargo/config.toml
|
||||
|
||||
Currently, we’d need to provide cargo with a target triple every time we run `cargo build` or `cargo run`. Let’s spare ourselves that work by copying `.cargo/config.toml` from `examples/stm32g4` into our project.
|
||||
|
||||

|
||||
└── main.rs
|
||||
----
|
||||
|
||||
In addition to a target triple, `.cargo/config.toml` contains a `runner` key which allows us to conveniently run our project on hardware with `cargo run` via probe-rs. In order for this to work, we need to provide the correct chip ID. We can do this by checking `probe-rs chip list`:
|
||||
|
||||
[source,bash]
|
||||
----
|
||||
$ probe-rs chip list | grep -i stm32g474re
|
||||
STM32G474RETx
|
||||
----
|
||||
|
||||
and copying `STM32G474RETx` into `.cargo/config.toml` as so:
|
||||
|
||||
[source,toml]
|
||||
----
|
||||
[target.'cfg(all(target_arch = "arm", target_os = "none"))']
|
||||
# replace STM32G071C8Rx with your chip as listed in `probe-rs chip list`
|
||||
runner = "probe-rs run --chip STM32G474RETx"
|
||||
----
|
||||
|
||||
== Cargo.toml
|
||||
|
||||
Now that cargo knows what target to compile for (and probe-rs knows what chip to run it on), we’re ready to add some dependencies.
|
||||
|
||||
Looking in `examples/stm32g4/Cargo.toml`, we can see that the examples require a number of embassy crates. For blinky, we’ll only need three of them: `embassy-stm32`, `embassy-executor` and `embassy-time`.
|
||||
|
||||
At the time of writing, the latest version of embassy isn‘t available on crates.io, so we need to install it straight from the git repository. The recommended way of doing so is as follows:
|
||||
|
||||
* Copy the required `embassy-*` lines from the example `Cargo.toml`
|
||||
* Make any necessary changes to `features`, e.g. requiring the `stm32g474re` feature of `embassy-stm32`
|
||||
* Remove the `path = ""` keys in the `embassy-*` entries
|
||||
* Create a `[patch.crates-io]` section, with entries for each embassy crate we need. These should all contain identical values: a link to the git repository, and a reference to the commit we’re checking out. Assuming you want the latest commit, you can find it by running `git ls-remote https://github.com/embassy-rs/embassy.git HEAD`
|
||||
|
||||
NOTE: When using this method, it’s necessary that the `version` keys in `[dependencies]` match up with the versions defined in each crate’s `Cargo.toml` in the specificed `rev` under `[patch.crates.io]`. This means that when updating, you have to a pick a new revision, change everything in `[patch.crates.io]` to match it, and then correct any versions under `[dependencies]` which have changed. Hopefully this will no longer be necessary once embassy is released on crates.io!
|
||||
|
||||
At the time of writing, this method produces the following results:
|
||||
|
||||
[source,toml]
|
||||
----
|
||||
[dependencies]
|
||||
embassy-stm32 = {version = "0.1.0", features = ["defmt", "time-driver-any", "stm32g474re", "memory-x", "unstable-pac", "exti"]}
|
||||
embassy-executor = { version = "0.3.3", features = ["nightly", "arch-cortex-m", "executor-thread", "defmt", "integrated-timers"] }
|
||||
embassy-time = { version = "0.2", features = ["defmt", "defmt-timestamp-uptime", "tick-hz-32_768"] }
|
||||
|
||||
[patch.crates-io]
|
||||
embassy-time = { git = "https://github.com/embassy-rs/embassy", rev = "7703f47c1ecac029f603033b7977d9a2becef48c" }
|
||||
embassy-executor = { git = "https://github.com/embassy-rs/embassy", rev = "7703f47c1ecac029f603033b7977d9a2becef48c" }
|
||||
embassy-stm32 = { git = "https://github.com/embassy-rs/embassy", rev = "7703f47c1ecac029f603033b7977d9a2becef48c" }
|
||||
----
|
||||
|
||||
There are a few other dependencies we need to build the project, but fortunately they’re much simpler to install. Copy their lines from the example `Cargo.toml` to the the `[dependencies]` section in the new `Cargo.toml`:
|
||||
|
||||
[source,toml]
|
||||
----
|
||||
defmt = "0.3.5"
|
||||
defmt-rtt = "0.4.0"
|
||||
cortex-m = {version = "0.7.7", features = ["critical-section-single-core"]}
|
||||
cortex-m-rt = "0.7.3"
|
||||
panic-probe = "0.3.1"
|
||||
----
|
||||
|
||||
These are the bare minimum dependencies required to run `blinky.rs`, but it’s worth taking a look at the other dependencies specified in the example `Cargo.toml`, and noting what features are required for use with embassy – for example `futures = { version = "0.3.17", default-features = false, features = ["async-await"] }`.
|
||||
|
||||
Finally, copy the `[profile.release]` section from the example `Cargo.toml` into ours.
|
||||
|
||||
[source,toml]
|
||||
----
|
||||
[profile.release]

||||
debug = 2
|
||||
----
|
||||
|
||||
== rust-toolchain.toml
|
||||
|
||||
Before we can build our project, we need to add an additional file to tell cargo to use the nightly toolchain. Copy the `rust-toolchain.toml` from the embassy repo to ours, and trim the list of targets down to only the target triple relevent for our project — in this case, `thumbv7em-none-eabi`:

There are many ways to configure embassy and its components for your exact application. The link:https://github.com/embassy-rs/embassy/tree/main/examples[examples] directory for each chipset demonstrates how your project structure should look. Let's break it down:

|

By design, the bootloader does not provide any network capabilities. Networking capabilities for fetching new firmware can be provided by the user application, using the bootloader as a library for updating the firmware, or by using the bootloader as a library and adding this capability yourself.
|
||||
|
||||
## Overview
|
||||
|
||||
The bootloader divides the storage into 4 main partitions, configurable when creating the bootloader instance or via linker scripts:
|
||||
|
||||
* BOOTLOADER - Where the bootloader is placed. The bootloader itself consumes about 8kB of flash, but if you need to debug it and have space available, increasing this to 24kB will allow you to run the bootloader with probe-rs.
|
||||
* ACTIVE - Where the main application is placed. The bootloader will attempt to load the application at the start of this partition. The minimum size required for this partition is the size of your application.
|
||||
* DFU - Where the application-to-be-swapped is placed. This partition is written to by the application. This partition must be at least 1 page bigger than the ACTIVE partition.
|
||||
* BOOTLOADER STATE - Where the bootloader stores the current state describing if the active and dfu partitions need to be swapped.
|
||||
|
||||
For any partition, the following preconditions are required:
|
||||
|
||||
* Partitions must be aligned on the page size.
|
||||
* Partitions must be a multiple of the page size.
|
||||
|
||||
The linker scripts for the application and bootloader look similar, but the FLASH region must point to the BOOTLOADER partition for the bootloader, and the ACTIVE partition for the application.
|
||||
|
||||
For more details on the bootloader, see [the documentation](https://embassy.dev/book/dev/bootloader.html).
|
||||

## Unreleased
|
||||
|
||||
## 0.4.0 - 2023-12-05
|
||||
|
||||
- Removed `arch-xtensa`. Use the executor provided by the HAL crate (`esp-hal`, `esp32s3-hal`, etc...) instead.
|
||||
- Added an arena allocator for tasks, allowing using the `main` and `task` macros on Rust 1.75 stable. (it is only used if the `nightly` feature is not enabled. When `nightly` is enabled, `type_alias_impl_trait` is used to statically allocate tasks, as before).
|
||||
|
||||
## 0.3.3 - 2023-11-15
|
||||
|
||||
- Add `main` macro reexport for Xtensa arch.
|
||||
- Remove use of `atomic-polyfill`. The executor now has multiple implementations of its internal data structures for cases where the target supports atomics or doesn't.
|
||||
|
||||
## 0.3.2 - 2023-11-06
|
||||
|
||||
- Use `atomic-polyfill` for `riscv32`
|
||||
- Removed unused dependencies (static_cell, futures-util)
|
||||
|
||||
## 0.3.1 - 2023-11-01
|
||||
|
||||
- Fix spurious "Found waker not created by the Embassy executor" error in recent nightlies.
|
||||
|
||||
## 0.3.0 - 2023-08-25
|
||||
|
||||
- Replaced Pender. Implementations now must define an extern function called `__pender`.

An async/await executor designed for embedded usage.

|
||||
- No `alloc`, no heap needed.
|
||||
- With nightly Rust, task futures can be fully statically allocated.
|
||||
- No `alloc`, no heap needed. Task futures are statically allocated.
|
||||
- No "fixed capacity" data structures, executor works with 1 or 1000 tasks without needing config/tuning.
|
||||
- Integrated timer queue: sleeping is easy, just do `Timer::after_secs(1).await;`.
|
||||
- No busy-loop polling: CPU sleeps when there's no work to do, using interrupts or `WFE/SEV`.
|
||||
- Efficient polling: a wake will only poll the woken task, not all of them.
|
||||
- Fair: a task can't monopolize CPU time even if it's constantly being woken. All other tasks get a chance to run before a given task gets polled for the second time.
|
||||
- Creating multiple executor instances is supported, to run tasks with multiple priority levels. This allows higher-priority tasks to preempt lower-priority tasks.
|
||||
|
||||
## Task arena
|
||||
|
||||
When the `nightly` Cargo feature is not enabled, `embassy-executor` allocates tasks out of an arena (a very simple bump allocator).
|
||||
|
||||
If the task arena gets full, the program will panic at runtime. To guarantee this doesn't happen, you must set the size to the sum of sizes of all tasks.
|
||||
|
||||
Tasks are allocated from the arena when spawned for the first time. If the task exists, the allocation is not released to the arena, but can be reused to spawn the task again. For multiple-instance tasks (like `#[embassy_executor::task(pool_size = 4)]`), the first spawn will allocate memory for all instances. This is done for performance and to increase predictability (for example, spawning at least 1 instance of every task at boot guarantees an immediate panic if the arena is too small, while allocating instances on-demand could delay the panic to only when the program is under load).
|
||||
|
||||
The arena size can be configured in two ways:
|
||||
|
||||
- Via Cargo features: enable a Cargo feature like `task-arena-size-8192`. Only a selection of values
|
||||
is available, check `Cargo.toml` for the list.
|
||||
- Via environment variables at build time: set the variable named `EMBASSY_EXECUTOR_TASK_ARENA_SIZE`. For example
|
||||
`EMBASSY_EXECUTOR_TASK_ARENA_SIZE=4321 cargo build`. You can also set them in the `[env]` section of `.cargo/config.toml`.
|
||||
Any value can be set, unlike with Cargo features.
|
||||
|
||||
Environment variables take precedence over Cargo features. If two Cargo features are enabled for the same setting
|
||||
with different values, compilation fails.
|
||||
|
||||
## Statically allocating tasks
|
||||
|
||||
When using nightly Rust, enable the `nightly` Cargo feature. This will make `embassy-executor` use the `type_alias_impl_trait` feature to allocate all tasks in `static`s. Each task gets its own `static`, with the exact size to hold the task (or multiple instances of it, if using `pool_size`) calculated automatically at compile time. If tasks don't fit in RAM, this is detected at compile time by the linker. Runtime panics due to running out of memory are not possible.
|
||||
|
||||
The configured arena size is ignored, no arena is used at all.

# embassy-macros
|
||||
|
||||
An [Embassy](https://embassy.dev) project.
|
||||
|
||||
Macros for creating the main entry point and tasks that can be spawned by `embassy-executor`.
|
||||
|
||||
NOTE: The macros are re-exported by the `embassy-executor` crate which should be used instead of adding a direct dependency on the `embassy-macros` crate.
|
||||
|
||||
## Minimum supported Rust version (MSRV)
|
||||
|
||||
The `task` and `main` macros require the type alias impl trait (TAIT) nightly feature in order to compile.
