Vorago Rust Workspace
========
Vorago VA108xx Rust Support
=========
Workspace for developing Rust code for the Vorago devices
This crate collection provided support to write Rust applications for the VA108XX family
of devices.
After cloning, run
## List of crates
This workspace contains the following released crates:
- The [`va108xx`](https://egit.irs.uni-stuttgart.de/rust/va108xx-rs/src/branch/main/va108xx) PAC
crate containing basic low-level register definition.
- The [`va108xx-hal`](https://egit.irs.uni-stuttgart.de/rust/va108xx-rs/src/branch/main/va108xx-hal)
HAL crate containing higher-level abstractions on top of the PAC register crate.
- The [`vorago-reb1`](https://egit.irs.uni-stuttgart.de/rust/va108xx-rs/src/branch/main/vorago-reb1)
BSP crate containing support for the REB1 development board.
It also contains the following helper crates:
- The `board-tests` contains an application which can be used to test the libraries on the
board.
- The `examples` crates contains various example applications for the HAL and the PAC.
## Using the `.cargo/config.toml` file
Use the following command to have a starting `config.toml` file
```sh
git submodule update --init
cp .cargo/def-config.toml .cargo/config.toml
```
# Preparing the Rust installation
You then can adapt the `config.toml` to your needs. For example, you can configure runners
to conveniently flash with `cargo run`.
## Using the sample VS Code files
Building an application for the VA108XX family requires the `thumbv6m-none-eabi`
cross-compiler toolchain. If you have not installed it yet, you can do so with
Use the following command to have a starting configuration for VS Code:
```sh
rustup target add thumbv6m-none-eabi
cp -rT vscode .vscode
```
# Debugging with VS Code
You can then adapt the files in `.vscode` to your needs.
The REB1 board features an on-board JTAG, so all that is required to flash the board is a
Micro-USB cable and an
You can debug applications on the REB1 board with a graphical user interface using VS Code with
## Flashing, running and debugging the software
You can use CLI or VS Code for flashing, running and debugging. In any case, take
care of installing the pre-requisites first.
### Pre-Requisites
1. [SEGGER J-Link tools](https://www.segger.com/downloads/jlink/) installed
2. [gdb-multiarch](https://packages.debian.org/sid/gdb-multiarch) or similar
cross-architecture debugger installed. All commands here assume `gdb-multiarch`.
### Using CLI
You can build the blinky example application with the following command
```sh
cargo build --example blinky
```
Start the GDB server first. The server needs to be started with a certain configuration and with
a JLink script to disable ROM protection.
For example, on Debian based system the following command can be used to do this (this command
is also run when running the `jlink-gdb.sh` script)
```sh
JLinkGDBServer -select USB -device Cortex-M0 -endian little -if JTAG-speed auto \
-LocalhostOnly
```
After this, you can flash and debug the application with the following command
```sh
gdb-mutliarch -q -x jlink/jlink.gdb target/thumbv6m-none-eabihf/debug/examples/blinky
```
Please note that you can automate all steps except starting the GDB server by using a cargo
runner configuration, for example with the following lines in your `.cargo/config.toml` file:
```toml
[target.'cfg(all(target_arch = "arm", target_os = "none"))']
runner = "gdb-multiarch -q -x jlink/jlink.gdb"
```
After that, you can simply use `cargo run --example blinky` to flash the blinky
example.
### Using VS Code
Assuming a working debug connection to your VA108xx board, you can debug using VS Code with
the [`Cortex-Debug` plugin](https://marketplace.visualstudio.com/items?itemName=marus25.cortex-debug).
Some sample configuration files for VS code were provided as well. You can simply use `Run and Debug`
Some sample configuration files for VS code were provided and can be used by running
`cp -rT vscode .vscode` like specified above. After that, you can use `Run and Debug`
to automatically rebuild and flash your application.
The `tasks.json` and the `launch.json` files are generic and you can use them immediately by
opening the folder in VS code or adding it to a workspace.
If you would like to use a custom GDB application, you can specify the gdb binary in the following
configuration variables in your `settings.json`:

defmt Testapp
======
`defmt` is clunky to use without probe-rs and requires special configuration inside the
`.cargo/config.toml` file.
`probe-rs` is currently problematic for usage with the VA108xx , so it is not the default tool
recommended and used for the whole workspace. This project contains an isolated, `defmt` compatible
configuration for testing with `defmt` (and `probe-rs`).

# HAL for the Vorago VA108xx MCU family
This repository contains the **H**ardware **A**bstraction **L**ayer (HAL), which is an additional
hardware abstraction on top of the [peripheral access API](https://egit.irs.uni-stuttgart.de/rust/va108xx).
It is the result of reading the datasheet for the device and encoding a type-safe layer over the
raw PAC. This crate also implements traits specified by the
[embedded-hal](https://github.com/rust-embedded/embedded-hal) project, making it compatible with
various drivers in the embedded rust ecosystem.
In contrats to other HAL implementations, there is only one chip variant available here so there
is no need to pass the chip variant as a feature.
## Supported Boards
The first way to use this HAL will probably be with the
[REB1 development board](https://www.voragotech.com/products/reb1-va108x0-development-board-0).
The BSP provided for this board also contains instructions how to flash the board.
| Crate | Version |
|:------|:--------|
[vorago-reb1](https://crates.io/crates/vorago-reb1) | [![Crates.io](https://img.shields.io/crates/v/vorago-reb1)](https://crates.io/crates/vorago-reb1) |
## Building
Building an application requires the `thumbv6m-none-eabi` cross-compiler toolchain.
If you have not installed it yet, you can do so with
```sh
rustup target add thumbv6m-none-eabi
```
After that, you can use `cargo build` to build the development version of the crate.
If you have not done this yet, it is recommended to read some of the excellent resources
available to learn Rust:
- [Rust Embedded Book](https://docs.rust-embedded.org/book/)
- [Rust Discovery Book](https://docs.rust-embedded.org/discovery/)
## Examples
Some examples, which are not specific to a particular board were provided as well.
You can build the timer example with
```sh
cargo build --example timer-ticks
```
## Setting up your own binary crate
If you have a custom board, you might be interested in setting up a new binary crate for your
project. These steps aim to provide a complete list to get a binary crate working to flash
your custom board.
The hello world of embedded development is usually to blinky a LED. This example
is contained within the
[examples folder](https://egit.irs.uni-stuttgart.de/rust/va108xx-hal/src/branch/main/examples/blinky.rs).
1. Set up your Rust cross-compiler if you have not done so yet. See more in the [build chapter](#Building)
2. Create a new binary crate with `cargo init`
3. To ensure that `cargo build` cross-compiles, it is recommended to create a `.cargo/config.toml`
file. A sample `.cargo/config.toml` file is provided in this repository as well
4. Copy the `memory.x` file into your project. This file contains information required by the linker.
5. Copy the `blinky.rs` file to the `src/main.rs` file in your binary crate
6. You need to add some dependencies to your `Cargo.toml` file
```toml
[dependencies]
cortex-m = "<Compatible Version>"
cortex-m-rt = "<Compatible Version>"
panic-halt = "<Compatible Version>"
embedded-hal = "<Compatible Version>"
[dependencies.va108xx-hal]
version = "<Most Recent Version>"
features = ["rt"]
```
6. Build the application with `cargo build`
7. Flashing the board might work differently for different boards and there is usually
more than one way. You can find example instructions for the REB1 development board
[here](https://egit.irs.uni-stuttgart.de/rust/vorago-reb1).

//! # Type-erased, value-level module for GPIO pins
//!
//! Although the type-level API is generally preferred, it is not suitable in
//! all cases. Because each pin is represented by a distinct type, it is not
//! possible to store multiple pins in a homogeneous data structure. The
//! value-level API solves this problem by erasing the type information and
//! tracking the pin at run-time.
//!
//! Value-level pins are represented by the [`DynPin`] type. [`DynPin`] has two
//! fields, `id` and `mode` with types [`DynPinId`] and [`DynPinMode`]
//! respectively. The implementation of these types closely mirrors the
//! type-level API.
//!
//! Instances of [`DynPin`] cannot be created directly. Rather, they must be
//! created from their type-level equivalents using [`From`]/[`Into`].
//!
//! ```
//! // Move a pin out of the Pins struct and convert to a DynPin
//! let pa0: DynPin = pins.pa0.into();
//! ```
//!
//! Conversions between pin modes use a value-level version of the type-level
//! API.
//!
//! ```
//! // Use one of the literal function names
//! pa0.into_floating_input();
//! // Use a method and a DynPinMode variant
//! pa0.into_mode(DYN_FLOATING_INPUT);
//! ```
//!
//! Because the pin state cannot be tracked at compile-time, many [`DynPin`]
//! operations become fallible. Run-time checks are inserted to ensure that
//! users don't try to, for example, set the output level of an input pin.
//!
//! Users may try to convert value-level pins back to their type-level
//! equivalents. However, this option is fallible, because the compiler cannot
//! guarantee the pin has the correct ID or is in the correct mode at
//! compile-time. Use [`TryFrom`](core::convert::TryFrom)/
//! [`TryInto`](core::convert::TryInto) for this conversion.
//!
//! ```
//! // Convert to a `DynPin`
//! let pa0: DynPin = pins.pa0.into();
//! // Change pin mode
//! pa0.into_floating_input();
//! // Convert back to a `Pin`
//! let pa0: Pin<PA0, FloatingInput> = pa0.try_into().unwrap();
//! ```
//!
//! # Embedded HAL traits
//!
//! This module implements all of the embedded HAL GPIO traits for [`DynPin`].
//! However, whereas the type-level API uses
//! `Error = core::convert::Infallible`, the value-level API can return a real
//! error. If the [`DynPin`] is not in the correct [`DynPinMode`] for the
//! operation, the trait functions will return
//! [`InvalidPinType`](PinError::InvalidPinType).

//! # API for the GPIO peripheral
//!
//! The implementation of this GPIO module is heavily based on the
//! [ATSAMD HAL implementation](https://docs.rs/atsamd-hal/latest/atsamd_hal/gpio/index.html).
//!
//! This API provides two different submodules, [`mod@pins`] and [`dynpins`],
//! representing two different ways to handle GPIO pins. The default, [`mod@pins`],
//! is a type-level API that tracks the state of each pin at compile-time. The
//! alternative, [`dynpins`] is a type-erased, value-level API that tracks the
//! state of each pin at run-time.
//!
//! The type-level API is strongly preferred. By representing the state of each
//! pin within the type system, the compiler can detect logic errors at
//! compile-time. Furthermore, the type-level API has absolutely zero run-time
//! cost.
//!
//! If needed, [`dynpins`] can be used to erase the type-level differences
//! between pins. However, by doing so, pins must now be tracked at run-time,
//! and each pin has a non-zero memory footprint.
//!
//! ## Examples
//!
//! - [Blinky example](https://egit.irs.uni-stuttgart.de/rust/va108xx-hal/src/branch/main/examples/blinky.rs)

//! # Type-level module for GPIO pins
//!
//! This documentation is strongly based on the
//! [atsamd documentation](https://docs.rs/atsamd-hal/latest/atsamd_hal/gpio/pin/index.html).
//!
//! This module provides a type-level API for GPIO pins. It uses the type system
//! to track the state of pins at compile-time. Representing GPIO pins in this
//! manner incurs no run-time overhead. Each [`Pin`] struct is zero-sized, so
//! there is no data to copy around. Instead, real code is generated as a side
//! effect of type transformations, and the resulting assembly is nearly
//! identical to the equivalent, hand-written C.
//!
//! To track the state of pins at compile-time, this module uses traits to
//! represent [type classes] and types as instances of those type classes. For
//! example, the trait [`InputConfig`] acts as a [type-level enum] of the
//! available input configurations, and the types [`Floating`], [`PullDown`] and
//! [`PullUp`] are its type-level variants.
//!
//! Type-level [`Pin`]s are parameterized by two type-level enums, [`PinId`] and
//! [`PinMode`].
//!
//! ```
//! pub struct Pin<I, M>
//! where
//! I: PinId,
//! M: PinMode,
//! {
//! // ...
//! }
//! ```
//!
//! A `PinId` identifies a pin by it's group (A, B, C or D) and pin number. Each
//! `PinId` instance is named according to its datasheet identifier, e.g.
//! [`PA02`].
//!
//! A `PinMode` represents the various pin modes. The available `PinMode`
//! variants are [`Disabled`], [`Input`], [`Interrupt`], [`Output`] and
//! [`Alternate`], each with its own corresponding configurations.
//!
//! It is not possible for users to create new instances of a [`Pin`]. Singleton
//! instances of each pin are made available to users through the [`Pins`]
//! struct.
//!
//! To create the [`Pins`] struct, users must supply the PAC
//! [`PORT`](crate::pac::PORT) peripheral. The [`Pins`] struct takes
//! ownership of the [`PORT`] and provides the corresponding pins. Each [`Pin`]
//! within the [`Pins`] struct can be moved out and used individually.
//!
//!
//! ```
//! let mut peripherals = Peripherals::take().unwrap();
//! let pins = Pins::new(peripherals.PORT);
//! ```
//!
//! Pins can be converted between modes using several different methods.
//!
//! ```
//! // Use one of the literal function names
//! let pa27 = pins.pa27.into_floating_input();
//! // Use a generic method and one of the `PinMode` variant types
//! let pa27 = pins.pa27.into_mode::<FloatingInput>();
//! // Specify the target type and use `From`/`Into`
//! let pa27: Pin<PA27, FloatingInput> = pins.pa27.into();
//! ```
//!
//! # Embedded HAL traits
//!
//! This module implements all of the embedded HAL GPIO traits for each [`Pin`]
//! in the corresponding [`PinMode`]s, namely: [`InputPin`], [`OutputPin`],
//! [`ToggleableOutputPin`] and [`StatefulOutputPin`].
//!
//! For example, you can control the logic level of an `OutputPin` like so
//!
//! ```
//! use atsamd_hal::pac::Peripherals;
//! use atsamd_hal::gpio::Pins;
//! use crate::ehal_02::digital::v2::OutputPin;
//!
//! let mut peripherals = Peripherals::take().unwrap();
//! let mut pins = Pins::new(peripherals.PORT);
//! pins.pa27.set_high();
//! ```
//!
//! # Type-level features
//!
//! This module also provides additional, type-level tools to work with GPIO
//! pins.
//!
//! The [`OptionalPinId`] and [`OptionalPin`] traits use the [`OptionalKind`]
//! pattern to act as type-level versions of [`Option`] for `PinId` and `Pin`
//! respectively. And the [`AnyPin`] trait defines an [`AnyKind`] type class
//! for all `Pin` types.
//!
//! [type classes]: crate::typelevel#type-classes
//! [type-level enum]: crate::typelevel#type-level-enum
//! [`OptionalKind`]: crate::typelevel#optionalkind-trait-pattern
//! [`AnyKind`]: crate::typelevel#anykind-trait-pattern

This directory is intended for project header files.
A header file is a file containing C declarations and macro definitions
to be shared between several project source files. You request the use of a
header file in your project source file (C, C++, etc) located in `src` folder
by including it, with the C preprocessing directive `#include'.
```src/main.c
#include "header.h"
int main (void)
{
...
}
```
Including a header file produces the same results as copying the header file
into each source file that needs it. Such copying would be time-consuming
and error-prone. With a header file, the related declarations appear
in only one place. If they need to be changed, they can be changed in one
place, and programs that include the header file will automatically use the
new version when next recompiled. The header file eliminates the labor of
finding and changing all the copies as well as the risk that a failure to
find one copy will result in inconsistencies within a program.
In C, the usual convention is to give header files names that end with `.h'.
It is most portable to use only letters, digits, dashes, and underscores in
header file names, and at most one dot.
Read more about using header files in official GCC documentation:
* Include Syntax
* Include Operation
* Once-Only Headers
* Computed Includes

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into executable file.
The source code of each library should be placed in a an own separate directory
("lib/your_library_name/[here are source files]").
For example, see a structure of the following two libraries `Foo` and `Bar`:
|--lib
| |
| |--Bar
| | |--docs
| | |--examples
| | |--src
| | |- Bar.c
| | |- Bar.h
| | |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
| |
| |--Foo
| | |- Foo.c
| | |- Foo.h
| |
| |- README --> THIS FILE
|
|- platformio.ini
|--src
|- main.c
and a contents of `src/main.c`:
```
#include <Foo.h>
#include <Bar.h>
int main (void)
{
...
}
```
PlatformIO Library Dependency Finder will find automatically dependent
libraries scanning project source files.

This directory is intended for PlatformIO Unit Testing and project tests.
Unit Testing is a software testing method by which individual units of
source code, sets of one or more MCU program modules together with associated
control data, usage procedures, and operating procedures, are tested to
determine whether they are fit for use. Unit testing finds problems early
in the development cycle.

# PAC for the Vorago VA108xx microcontroller family
This repository contains the Peripheral Access Crate (PAC) for
Voragos VA108xx series of Cortex-M0 based microcontrollers.
The crate was generated using [`svd2rust`](https://github.com/rust-embedded/svd2rust).
If you are interested in higher-level abstractions, it is recommended you visit
the [`va108xx-hal` HAL crate](https://egit.irs.uni-stuttgart.de/rust/va108xx-hal) and
the [`vorago-reb1` BSP crate](https://github.com/robamu-org/vorago-reb1-rs) which build on top of
this PAC and provide application examples as well.
## Usage
To use this crate, add this to your `Cargo.toml`
```toml
[dependencies.va108xx]
version = "<Most Recent Version>"
features = ["rt"]
```
The `rt` feature is optional and recommended. It brings in support for `cortex-m-rt`.
For full details on the autgenerated API, please see the
[svd2rust documentation](https://docs.rs/svd2rust/0.19.0/svd2rust/#peripheral-api).
## Regenerating the PAC
If you want to re-generate the PAC, for example if the register file `va416xx.svd` changes
or the `svd2rust` version is updated, you can do some using the following these steps:
1. Make sure all necessary tools are installed: [`svd2rust`](https://docs.rs/svd2rust/latest/svd2rust/),
[`svdtools`](https://github.com/rust-embedded/svdtools) and [`form`](https://crates.io/crates/form).
You can install all tools with `cargo`:
```sh
cargo install --locked svd2rust svdtools form
```
2. Patch the vendor-provided SVD file `svd/va41xx.svd`. This can be done using `svdtools` in
conjunction with the `svd/va108xx-patch.yml` file.
```sh
svdtools patch svd/va108xx-patch.yml
```
3. Use `svd2rust` to generate the Rust library
```sh
svd2rust -i svd/va108xx.svd.patched
```
4. Use the `form` tool to split the generated `lib.rs` into individual modules.
```sh
form -i lib.rs -o src/
```
The `gen-helper.sh` automates steps 2-4.
