Introduction
This is the rp2040-hal package - a library crate of high-level Rust drivers
for the Raspberry Silicon RP2040 microcontroller, along with a collection of
non-board specific example programs for you to study. You should use this crate
in your application if you want to write code for the RP2040 microcontroller.
The HAL in the name standards for Hardware Abstraction Layer, and comes from
the fact that many of the drivers included implement the generic
hardware-abstraction interfaces defined in the Rust Embedded Working Group's
embedded-hal crate.
We also provide a series of Board Support Package (BSP) crates, which take
this HAL crate and pre-configure the pins according to a specific PCB design. If
you are using on of the supported boards, you should use one of those crates in
preference, and return here to see documentation about specific peripherals on
the RP2040 and how to use them. See the boards folder in
https://github.com/rp-rs/rp-hal/ for more details.
Getting Started
To include this crate in your project, amend your Cargo.toml file to include
rp2040-hal = "0.3"
To obtain a copy of the source code (e.g. if you want to propose a bug-fix or new feature, or simply to study the code), run:
$ git clone https://github.com/rp-rs/rp-hal.git
For details on how to program an RP2040 microcontroller, see the top-level rp-hal README.
Roadmap
NOTE This HAL is under active development. As such, it is likely to remain volatile until a 1.0.0 release.
See the open issues for a list of proposed features (and known issues).
Support for embedded-hal 1.0
We plan to support embedded-hal 1.0 soon after it is released.
For now, there is preliminary support for alpha versions of embedded-hal, which can
be enabled with the feature eh1_0_alpha. Please note that this support does not
provide any semver compatibility guarantees: With that feature activated, there
will be breaking changes even in minor versions of rp2040-hal.
Support for embedded-hal 1.0(-alpha) exists in parallel to support for embedded-hal 0.2: Traits of both versions are implemented and can be used at the same time.
