An example project demonstrating integration with Rust for the ESP32-S2 and ESP32-C3 microcontrollers.

Overview

Rust ESP32 Example

An example project demonstrating integration with Rust for the ESP32-S2 and ESP32-C3 microcontrollers.

This example starts a FreeRTOS task to call a function in Rust and display the results in C.

Setup

First, install the ESP-IDF SDK as shown in the Get Started guides. For best support of the ESP32-C3, install the SDK from the master branch.

ESP32 and ESP32-S series

To support the Xtensa instruction set, build and install custom LLVM and Rust toolchains as shown in the Rust On Xtensa guide.

ESP32-C3

Install the RISCV target for Rust:

rustup target add riscv32i-unknown-none-elf

Configure

First ensure that the environment variables for the ESP32 SDK are properly set up. If you have followed the instructions in the Getting Started guide, activate the environment with the get_idf alias:

get_idf

Next, configure the project for the desired MCU.

For the ESP32:

idf.py set-target esp32
idf.py menuconfig

For the ESP32-S2:

idf.py set-target esp32s2
idf.py menuconfig

For the ESP32-C3:

idf.py set-target esp32c3
idf.py menuconfig

Build

Build the project by running:

idf.py build

This also runs Cargo internally, building a static library out of Rust code.

Flash

Flash the compiled binary by running:

idf.py -p /dev/cu.SLAB_USBtoUART flash

Monitor

Connect to the UART over USB port to monitor the application console:

idf.py -p /dev/cu.SLABtoUART monitor

To exit the monitor, press Ctrl-].

Debugging on ESP32-WROVER-KIT

openocd -f board/esp32-wrover-kit-3.3v.cfg

  • Allow using esp-idf-svc with the CMake build

    Allow using esp-idf-svc with the CMake build

    Hi,

    Thanks for this really nice repository! We're a French company using ESP32 for our products, and we are really looking forward to being able to use embedded Rust.

    We saw both rust-esp32-example (this repo, CMake-based build) and https://github.com/ivmarkov/rust-esp32-std-hello (a nice "cargo-first" build from @ivmarkov which also allows to use the nice https://github.com/esp-rs/esp-idf-svc which gives access to nice Rust wrappers for most of ESP-IDF libraries).

    For now, because our codebase is C/C++, we'd be happy to use this CMake-based build rather than the "cargo-first" build (as we want to incrementally modify modules of our code by replacing them with Rust code), but it seems we can't use esp-idf-svc with it out-of-the-box.

    Would it be possible to update this code, or add an example of how to do a CMake-based build that also allows to use esp-idf-svc?

    The failure makes sense, since RV32I or RV32IMC don't support atomic instructions.

    This looks like https://github.com/rust-lang/rust/issues/62269, except this time in std_detect crate. I guess this is something that needs to be reported in https://github.com/rust-lang/stdarch/blob/82106e84345ee25366cd8a49a228d69fde795047/crates/std_detect/src/detect/cache.rs#L8?

  • Issues when compiling Rust library project to a static library

    Issues when compiling Rust library project to a static library

    Hi all,

    I'm trying to compile ttf-parser to a static library for another ESP-IDF C/C++ project. It has a C binding and it should just work as long as I change the target type from cdylib to staticlib (am I right? or have I forgot something?). However it didn't work somehow when opt-level is not 0 or s. Here's what I have done:

    1. I used the docker image, by docker pull espressif/idf-rust-examples then docker run -it espressif/idf-rust-examples
    2. I cloned the ttf-parser project, by: git clone https://github.com/RazrFalcon/ttf-parser
    3. Then I go to the c-api directory. I added a .cargo/config.toml, content listed below:
    [build]
    # Uncomment the relevant target for your chip here (ESP32, ESP32-S2 or ESP32-C3)
    target = "xtensa-esp32-espidf"
    #target = "xtensa-esp32s2-espidf"
    #target = "riscv32imc-esp-espidf"
    
    [target.xtensa-esp32-espidf]
    linker = "ldproxy"
    
    [target.xtensa-esp32s2-espidf]
    linker = "ldproxy"
    
    [target.riscv32imc-esp-espidf]
    linker = "ldproxy"
    
    [patch.crates-io]
    # This patch is a temporary workaround necessary until Rust 1.55 is out
    # You DON'T need it with stock nightly Rust 1.56 (but stock nightly only supports the ESP32-C3 chip)
    libc = { git = "https://github.com/ivmarkov/libc.git" }
    
    [unstable]
    configurable-env = true # No longer necessary since 1.56, as it was stabilized: https://github.com/rust-lang/cargo/blob/master/src/cargo/core/features.rs#L698
    extra-link-arg = true   # No longer necessary since 1.56, as it was stabilized: https://github.com/rust-lang/cargo/blob/master/src/cargo/core/features.rs#L695
    build-std = ["std", "panic_abort"]
    build-std-features = ["panic_immediate_abort"]
    patch-in-config = true
    
    
    1. I run cargo build --release --verbose. Then something goes wrong. Here are a few different variants:
    • If I leave the lto = true and default release opt-level (should be 3?) in the Cargo.toml, rustc constantly uses 100% CPU and never finish compiling (at least still running after 3 minutes on a machine with Ryzen 3700X, 32GB RAM)
    • If I comment lto = true out and default release opt-level (should be 3?) , rustc will not lock up. But instead it gives me this output:
    warning: Patch `libc v0.2.101 (https://github.com/ivmarkov/libc.git#7e83ba0a)` was not used in the crate graph.
    Check that the patched package version and available features are compatible
    with the dependency requirements. If the patch has a different version from
    what is locked in the Cargo.lock file, run `cargo update` to use the new
    version. This may also occur with an optional dependency that is not enabled.

  • docker: split images to idf-rust and idf-rust-examples

    docker: split images to idf-rust and idf-rust-examples

    Closes https://github.com/ivmarkov/rust-esp32-std-hello/pull/8

    The idea behind this PR is to have two images:

    • espressif/idf-rust - which contains Rust compiler and can be used in CI or base image for others
    • espressif/idf-rust-examples - images based on idf-rust which contains additional tools and examples

    Right now we have two examples:

    • "idf.py-first" approach in /opt/rust-esp32-example
    • "cargo-first" approach which dependes on cargo-pio in /opt/rust-esp32-std-hello - repo: https://github.com/ivmarkov/rust-esp32-std-hello.git

    I noticed ESP-IDF pthread.c implementation does not implement pthread_atfork. Am I right in assuming there's nothing I can do ATM? Is it a bug, pending implementation, or can't be implemented?

    In any case, this should probably be caught at compile time rather than link time. If you could point me to the right repository to where report this issue I'd appreciated it.

    Build fails

    After running the installation steps for ESP-IDF and esp-rs/rust-build as well as sourcing the environment for both esp-idf and the rust environment the build fails:

    get_idf
    source ~/esp32/rust-build/export-esp-rust.sh
    idf.py set-target esp32
    idf.py build
    

    The build fails with the following error:

    I am attempting to find a docker image that will let me build Rust apps for an Adafruit ESP32 feather. If I docker run -it espressif/idf-rust-examples it malfunctions and drops me back to the original shell.

  • Slow build time when using the Docker container

    Slow build time when using the Docker container

    Hi,

    thanks for the amazing work on Rust for embedded ESP, I've been successfully using the Docker container to build the code, but the last step of the build (the linking) seems to be very slow, taking perhaps 1h on my recent osX machine,

    do you know what could be the cause of this issue? For now this is a bit blocking, because we would love to use a containerized environment for development, but we can't have build times that are more than 1 or 2 minutes for a simple code
