No downstream restrictions. You may not offer or impose + any additional or different terms or conditions on, or + apply any Effective Technological Measures to, the + Licensed Material if doing so restricts exercise of the + Licensed Rights by any recipient of the Licensed + Material. + + 6.

Patent and trademark rights are not licensed under this + Public License. + + 3. To the extent possible, the Licensor waives any right to + collect royalties from You for the exercise of the Licensed + Rights, whether directly or through a collecting society + under any voluntary or waivable statutory or compulsory + licensing scheme.

You may satisfy the conditions in Section 3(a)(1) in any + reasonable manner based on the medium, means, and context in + which You Share the Licensed Material. For example, it may be + reasonable to satisfy the conditions by providing a URI or + hyperlink to a resource that includes the required + information. + + 3. If requested by the Licensor, You must remove any of the + information required by Section 3(a)(1)(A) to the extent + reasonably practicable. + + b. ShareAlike. + + In addition to the conditions in Section 3(a), if You Share + Adapted Material You produce, the following conditions also apply. + + 1. The Adapter's License You apply must be a Creative Commons + license with the same License Elements, this version or + later, or a BY-SA Compatible License. + + 2. You must include the text of, or the URI or hyperlink to, the + Adapter's License You apply. You may satisfy this condition + in any reasonable manner based on the medium, means, and + context in which You Share Adapted Material. + + 3. You may not offer or impose any additional or different terms + or conditions on, or apply any Effective Technological + Measures to, Adapted Material that restrict exercise of the + rights granted under the Adapter's License You apply. + + +Section 4 -- Sui Generis Database Rights. + +Where the Licensed Rights include Sui Generis Database Rights that +apply to Your use of the Licensed Material: + + a. for the avoidance of doubt, Section 2(a)(1) grants You the right + to extract, reuse, reproduce, and Share all or a substantial + portion of the contents of the database; + + b. if You include all or a substantial portion of the database + contents in a database in which You have Sui Generis Database + Rights, then the database in which You have Sui Generis Database + Rights (but not its individual contents) is Adapted Material, + + including for purposes of Section 3(b); and + c. You must comply with the conditions in Section 3(a) if You Share + all or a substantial portion of the contents of the database. + +For the avoidance of doubt, this Section 4 supplements and does not +replace Your obligations under this Public License where the Licensed +Rights include other Copyright and Similar Rights. + + +Section 5 -- Disclaimer of Warranties and Limitation of Liability. + + a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE + EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS + AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF + ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, + IMPLIED, STATUTORY, OR OTHER.

WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR + IN PART, THIS LIMITATION MAY NOT APPLY TO YOU. + + c. The disclaimer of warranties and limitation of liability provided + above shall be interpreted in a manner that, to the extent + possible, most closely approximates an absolute disclaimer and + waiver of all liability. + + +Section 6 -- Term and Termination. + + a. This Public License applies for the term of the Copyright and + Similar Rights licensed here. However, if You fail to comply with + this Public License, then Your rights under this Public License + terminate automatically. + + b. Where Your right to use the Licensed Material has terminated under + Section 6(a), it reinstates: + + 1. automatically as of the date the violation is cured, provided + it is cured within 30 days of Your discovery of the + violation; or + + 2. upon express reinstatement by the Licensor. + + For the avoidance of doubt, this Section 6(b) does not affect any + right the Licensor may have to seek remedies for Your violations + of this Public License. + + c. For the avoidance of doubt, the Licensor may also offer the + Licensed Material under separate terms or conditions or stop + distributing the Licensed Material at any time; however, doing so + will not terminate this Public License. + + d. Sections 1, 5, 6, 7, and 8 survive termination of this Public + License. + + +Section 7 -- Other Terms and Conditions. + + a. The Licensor shall not be bound by any additional or different + terms or conditions communicated by You unless expressly agreed. + + b. Any arrangements, understandings, or agreements regarding the + Licensed Material not stated herein are separate from and + independent of the terms and conditions of this Public License. + + +Section 8 -- Interpretation. + + a. For the avoidance of doubt, this Public License does not, and + shall not be interpreted to, reduce, limit, restrict, or impose + conditions on any use of the Licensed Material that could lawfully + be made without permission under this Public License. + + b. To the extent possible, if any provision of this Public License is + deemed unenforceable, it shall be automatically reformed to the + minimum extent necessary to make it enforceable. If the provision + cannot be reformed, it shall be severed from this Public License + without affecting the enforceability of the remaining terms and + conditions. + + c. No term or condition of this Public License will be waived and no + failure to comply consented to unless expressly agreed to by the + Licensor. + + d.

Specifically you will want to see the size of the `.data` and `.bss` sections, which together make up the total global/static memory usage. + +=== For Max Stack Usage + +Check out link:https://github.com/Dirbaio/cargo-call-stack/[`cargo-call-stack`] for statically calculating worst-case stack usage. There are some caveats and inaccuracies possible with this, but this is a good way to get the general idea. See link:https://github.com/dirbaio/cargo-call-stack#known-limitations[the README] for more details. + +== The memory definition for my STM chip seems wrong, how do I define a `memory.x` file? + +It could happen that your project compiles, flashes but fails to run. The following situation can be true for your setup: + +The `memory.x` is generated automatically when enabling the `memory-x` feature on the `embassy-stm32` crate in the `Cargo.toml` file. +This, in turn, uses `stm32-metapac` to generate the `memory.x` file for you. Unfortunately, more often than not this memory definition is not correct. + +You can override this by adding your own `memory.x` file. Such a file could look like this: +``` +MEMORY +{ + FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 1024K + RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 320K +} + +_stack_start = ORIGIN(RAM) + LENGTH(RAM); +``` + +Please refer to the STM32 documentation for the specific values suitable for your board and setup. The STM32 Cube examples often contain a linker script `.ld` file. +Look for the `MEMORY` section and try to determine the FLASH and RAM sizes and section start. + +If you find a case where the memory.x is wrong, please report it on [this Github issue](https://github.com/embassy-rs/stm32-data/issues/301) so other users are not caught by surprise. + +== The USB examples are not working on my board, is there anything else I need to configure? + +If you are trying out the USB examples and your device doesn not connect, the most common issues are listed below. + +=== Incorrect RCC config + +Check your board and crystal/oscillator, in particular make sure that `HSE` is set to the correct value, e.g. `8_000_000` Hertz if your board does indeed run on a 8 MHz oscillator. + +=== VBUS detection on STM32 platform + +The USB specification requires that all USB devices monitor the bus for detection of plugging/unplugging actions. The devices must pull-up the D+ or D- lane as soon as the host supplies VBUS. + +See the docs, for example at link:https://docs.embassy.dev/embassy-stm32/git/stm32f401vc/usb/struct.Config.html[`usb/struct.Config.html`] for information on how to enable/disable `vbus_detection`. + +When the device is powered only from the USB bus that simultaneously serves as the data connection, this is optional. (If there's no power in VBUS the device would be off anyway, so it's safe to always assume there's power in VBUS, i.e. the USB cable is always plugged in). If your device doesn't have the required connections in place to allow VBUS sensing (see below), then this option needs to be set to `false` to work. + +When the device is powered from another power source and therefore can stay powered through USB cable plug/unplug events, then this must be implemented and `vbus_detection` MUST be set to `true`. + +If your board is powered from the USB and you are unsure whether it supports `vbus_detection`, consult the schematics of your board to see if VBUS is connected to PA9 for USB Full Speed or PB13 for USB High Speed, vice versa, possibly with a voltage divider. When designing your own hardware, see ST application note AN4879 (in particular section 2.6) and the reference manual of your specific chip for more details. + +== Known issues (details and/or mitigations) + +These are issues that are commonly reported. Help wanted fixing them, or improving the UX when possible! + +=== STM32H5 and STM32H7 power issues + +STM32 chips with built-in power management (SMPS and LDO) settings often cause user problems when the configuration does not match how the board was designed. + +Settings from the examples, or even from other working boards, may not work on YOUR board, because they are wired differently. + +Additionally, some PWR settings require a full device reboot (and enough time to discharge any power capacitors!), making this hard to troubleshoot. Also, some +"wrong" power settings will ALMOST work, meaning it will sometimes work on some boots, or for a while, but crash unexpectedly. + +There is not a fix for this yet, as it is board/hardware dependant. See link:https://github.com/embassy-rs/embassy/issues/2806[this tracking issue] for more details + +=== STM32 BDMA only working out of some RAM regions + +The STM32 BDMA controller included in some STM32H7 chips has to be configured to use only certain regions of RAM, +otherwise the transfer will fail. + +If you see errors that look like this: + +[source,plain] +---- +DMA: error on BDMA@1234ABCD channel 4 +---- + +You need to set up your linker script to define a special region for this area and copy data to that region before using with BDMA. + +General steps: + +1. Find out which memory region BDMA has access to. You can get this information from the bus matrix and the memory mapping table in the STM32 datasheet. +2. Add the memory region to `memory.x`, you can modify the generated one from https://github.com/embassy-rs/stm32-data-generated/tree/main/data/chips. +3. You might need to modify `build.rs` to make cargo pick up the modified `memory.x`. +4. In your code, access the defined memory region using `#[link_section = ".xxx"]` +5. Copy data to that region before using BDMA. + +See link:https://github.com/embassy-rs/embassy/blob/main/examples/stm32h7/src/bin/spi_bdma.rs[SMT32H7 SPI BDMA example] for more details. + +== How do I switch to the `main` branch? + +Sometimes to test new changes or fixes, you'll want to switch your project to using a version from GitHub. + +You can add a section to your `Cargo.toml` file like this, you'll need to patch ALL embassy crates to the same revision: + +Using `patch` will replace all direct AND indirect dependencies. + +See the link:https://embassy.dev/book/#_starting_a_new_project[new project docs] for more details on this approach. + +[source,toml] +---- +[patch.crates-io] +# make sure to get the latest git rev from github, you can see the latest one here: +# https://github.com/embassy-rs/embassy/commits/main/ +embassy-embedded-hal = { git = "https://github.com/embassy-rs/embassy", rev = "4cade64ebd34bf93458f17cfe85c5f710d0ff13c" } +embassy-executor = { git = "https://github.com/embassy-rs/embassy", rev = "4cade64ebd34bf93458f17cfe85c5f710d0ff13c" } +embassy-rp = { git = "https://github.com/embassy-rs/embassy", rev = "4cade64ebd34bf93458f17cfe85c5f710d0ff13c" } +embassy-sync = { git = "https://github.com/embassy-rs/embassy", rev = "4cade64ebd34bf93458f17cfe85c5f710d0ff13c" } +embassy-time = { git = "https://github.com/embassy-rs/embassy", rev = "4cade64ebd34bf93458f17cfe85c5f710d0ff13c" } +embassy-usb = { git = "https://github.com/embassy-rs/embassy", rev = "4cade64ebd34bf93458f17cfe85c5f710d0ff13c" } +embassy-usb-driver = { git = "https://github.com/embassy-rs/embassy", rev = "4cade64ebd34bf93458f17cfe85c5f710d0ff13c" } +---- + +== How do I add support for a new microcontroller to embassy? + +This is particularly for cortex-m, and potentially risc-v, where there is already support for basics like interrupt handling, or even already embassy-executor support for your architecture. + +This is a *much harder path* than just using Embassy on an already supported chip. If you are a beginner, consider using embassy on an existing, well supported chip for a while, before you decide to write drivers from scratch. It's also worth reading the existing source of supported Embassy HALs, to get a feel for how drivers are implemented for various chips. You should already be comfortable reading and writing unsafe code, and understanding the responsibilities of writing safe abstractions for users of your HAL. + +This is not the only possible approach, but if you are looking for where to start, this is a reasonable way to tackle the task: + +1. First, drop by the Matrix room or search around to see if someone has already started writing drivers, either in Embassy or otherwise in Rust. You might not have to start from scratch! +2. Make sure the target is supported in probe-rs, it likely is, and if not, there is likely a cmsis-pack you can use to add support so that flashing and debugging is possible. You will definitely appreciate being able to debug with SWD or JTAG when writing drivers! +3. See if there is an SVD (or SVDs, if it's a family) available, if it is, run it through chiptool to create a PAC for low level register access. If not, there are other ways (like scraping the PDF datasheets or existing C header files), but these are more work than starting from the SVD file to define peripheral memory locations necessary for writing drivers. +4. Either make a fork of embassy repo, and add your target there, or make a repo that just contains the PAC and an empty HAL. It doesn't necessarily have to live in the embassy repo at first. +5. Get a hello world binary working on your chip, either with minimal HAL or just PAC access, use delays and blink a light or send some raw data on some interface, make sure it works and you can flash, debug with defmt + RTT, write a proper linker script, etc. +6. Get basic timer operations and timer interrupts working, upgrade your blinking application to use hardware timers and interrupts, and ensure they are accurate (with a logic analyzer or oscilloscope, if possible). +7. Implement the embassy-time driver API with your timer and timer interrupt code, so that you can use embassy-time operations in your drivers and applications. +8. Then start implementing whatever peripherals you need, like GPIOs, UART, SPI, I2C, etc. This is the largest part of the work, and will likely continue for a while! Don't feel like you need 100% coverage of all peripherals at first, this is likely to be an ongoing process over time. +9. Start implementing the embedded-hal, embedded-io, and embedded-hal-async traits on top of your HAL drivers, once you start having more features completed. This will allow users to use standard external device drivers (e.g. sensors, actuators, displays, etc.) with your HAL. +10. Discuss upstreaming the PAC/HAL for embassy support, or make sure your drivers are added to the awesome-embedded-rust list so that people can find it. + +== Multiple Tasks, or one task with multiple futures? + +Some examples end like this in main: + +[source,rust] +---- +// Run everything concurrently. +// If we had made everything `'static` above instead, we could do this using separate tasks instead. +join(usb_fut, join(echo_fut, log_fut)).await; +---- + +There are two main ways to handle concurrency in Embassy: + +1. Spawn multiple tasks, e.g. with `#[embassy_executor::task]` +2. Manage multiple futures inside ONE task using `join()` or `select()` (as shown above) + +In general, either of these approaches will work. The main differences of these approaches are: + +When using **separate tasks**, each task needs its own RAM allocation, so there's a little overhead for each task, so one task that does three things will likely be a little bit smaller than three tasks that do one thing (not a lot, probably a couple dozen bytes). In contrast, with **multiple futures in one task**, you don't need multiple task allocations, and it will generally be easier to share data, or use borrowed resources, inside of a single task. +An example showcasing some methods for sharing things between tasks link:https://github.com/embassy-rs/embassy/blob/main/examples/rp/src/bin/sharing.rs[can be found here]. + +But when it comes to "waking" tasks, for example when a data transfer is complete or a button is pressed, it's faster to wake a dedicated task, because that task does not need to check which future is actually ready. `join` and `select` must check ALL of the futures they are managing to see which one (or which ones) are ready to do more work. This is because all Rust executors (like Embassy or Tokio) only have the ability to wake tasks, not specific futures. This means you will use slightly less CPU time juggling futures when using dedicated tasks. + +Practically, there's not a LOT of difference either way - so go with what makes it easier for you and your code first, but there will be some details that are slightly different in each case. + +== splitting peripherals resources between tasks + +There are two ways to split resources between tasks, either manually assigned or by a convenient macro. See link:https://github.com/embassy-rs/embassy/blob/main/examples/rp/src/bin/assign_resources.rs[this example] + +== My code/driver works in debug mode, but not release mode (or with LTO) + +Issues like these while implementing drivers often fall into one of the following general causes, which are a good list of common errors to check for: + +1. Some kind of race condition - the faster code means you miss an interrupt or something +2. Some kind of UB, if you have unsafe code, or something like DMA with fences missing +3. Some kind of hardware errata, or some hardware misconfiguration like wrong clock speeds +4. Some issue with an interrupt handler, either enabling, disabling, or re-enabling of interrupts when necessary +5. Some kind of async issue, like not registering wakers fully before checking flags, or not registering or pending wakers at the right time diff --git a/vendor/embassy/docs/modules/ROOT/pages/getting_started.adoc b/vendor/embassy/docs/pages/getting_started.adoc similarity index 61% rename from vendor/embassy/docs/modules/ROOT/pages/getting_started.adoc rename to vendor/embassy/docs/pages/getting_started.adoc index 24bde1c..0174090 100644 --- a/vendor/embassy/docs/modules/ROOT/pages/getting_started.adoc +++ b/vendor/embassy/docs/pages/getting_started.adoc @@ -3,7 +3,7 @@ So you want to try Embassy, great!

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.

The documentation here on `docs.rs` is built for a single chip only (stm32h7, stm32h7rs55 in particular), while on the Embassy website you can pick your exact chip from the top menu. Available peripherals and their APIs change depending on the chip.
