Develop embedded systems firmware with Rust for safety, performance, and modern tooling. #![nostd] enables bare-metal code without the standard library. The Embedded HAL provides portable hardware abstraction. cortex-m-rt handles vector table and startup. Use probe-rs for flashing and debugging. Firmware for ARM Cortex-M, RISC-V microcontrollers IoT sensor nodes and actuators Safety-critical embedded systems Replacing C/C++ with memory-safe Rust 1. Pick the board/target: install rustup target add thumbv7em-none-eabihf for Cortex-M4F or the RISC-V equivalent. 2. Configure the linker: add .cargo/config.toml with rustflags (link.x) and default build target. 3. Scaffold a nostd crate: use #![nostd] + #![nomain], add cortex-m-rt for startup and a panic handler. 4. Get a HAL: enable stm32f4xxhal (or nrf-hal, esp-hal) peripheral features matching the chip. 5. Flash & debug: use probe-rs/cargo embed (or openocd + gdb-multiarch) with the target config. 6. Verify on device: blink an LED, then exercise a sensor/UART; check binary size with cargo size. Use nostd crates for bare-metal targets. Keep memory and stack usage bounded and profiled. Use interrupts and DMA for I/O; avoid busy polling.
