Learn EMBEDDED-RUST with Real Code Examples

Install Rust via rustup

Add target for the microcontroller (e.g., `thumbv7em-none-eabihf`)

Install `cargo-binutils` and `probe-rs` for flashing/debugging

Set up project structure with `cargo new --lib` or `cargo new --bin`

Test with a simple blinky example to validate setup

Install Rust via rustup

Add target for microcontroller

Install embedded tools (probe-rs, cargo-binutils)

Clone/initialize project with Cargo

Test with a basic LED blink example

Cargo.toml - Rust project configuration

src/main.rs - main firmware entry

src/lib.rs - library modules

boards/ - board-specific configurations

.cargo/config.toml - target and toolchain config

Optional examples/ and tests/

cargo build --target <target> - Compile for embedded target

cargo run - Run on host (for simulation/testing)

cargo flash - Flash firmware to device via probe

cargo test - Run unit tests

probe-rs debug - Debug microcontroller via probe

Documentation in English primarily

Comments and code can follow any locale

Crates support multiple locales where applicable

Embedded hardware is language-agnostic

Community translations growing

Accessible via open-source Rust tooling

Remote flashing and debugging possible via probes

Documentation and examples widely available

Cross-platform host tooling (Linux, macOS, Windows)

Community resources for learning and troubleshooting

Minimal; usually no UI in bare-metal

Optional LEDs, displays, or serial console for feedback

RTIC tasks may trigger outputs to indicators

Embedded dashboards possible with external devices

Visualization typically offloaded to host or cloud

Variables and peripherals managed via ownership

RTIC or interrupt-driven frameworks manage task state

no_std requires explicit memory handling

Static variables used for global device state

Peripheral access through safe Rust abstractions

Direct memory access via PAC registers

Buffers and arrays for sensor/actuator data

Persistent storage via flash or EEPROM

Host communication via UART/SPI/I2C

Data logging via semihosting or RTT for debugging
