EMBEDDED RUST SYSTEMS

FAQ #

• Why Rust instead of C for embedded firmware?

  Rust gives you C-level performance with compile-time memory safety. No garbage collector, no runtime overhead. The compiler catches buffer overflows, race conditions, and use-after-free before code touches hardware — the bug classes responsible for most embedded field failures.
• Can you work with our existing C firmware?

  Yes. Rust’s C FFI lets us add new modules in Rust that integrate directly with your existing C codebase. No forced rewrite. We migrate incrementally — one peripheral, one driver, one subsystem at a time.
• Which microcontrollers and platforms do you support?

  STM32 (Cortex-M0/M3/M4/M7), ESP32 (Xtensa and RISC-V), Nordic nRF (BLE SoCs), RP2040, and custom ARM/RISC-V targets. We work with your target silicon — not a simulator.
• How do you handle real-time constraints?

  We design firmware with deterministic execution paths — interrupt priorities, DMA transfers, lock-free data structures. For hard real-time requirements, we integrate with an RTOS (FreeRTOS, Zephyr) and validate timing with logic analyzers and hardware profiling.
• What if Rust doesn’t support our specific hardware?

  If a HAL crate doesn’t exist for your MCU, we write one. Rust’s SVD-to-PAC toolchain generates register-level access code from your chip’s datasheet. We’ve built custom HALs for targets without ecosystem support.
• Do you handle wireless connectivity?

  Yes. BLE, WiFi, LoRa, MQTT, Zigbee, and CAN bus. We architect communication layers that coexist with real-time control loops — proper interrupt priorities, power management, and OTA update systems that don’t brick devices.
• Do you sign NDAs?

  Yes. We sign NDAs before any technical discussion begins, on request.
• Who owns the code after delivery?

  You do. IP, source code, firmware binaries, and hardware documentation are fully assigned to you on completion — no vendor lock-in.
• Do you work with formal contracts?

  Yes. Signed contracts with fixed scope per phase. You’re contracting with a registered entity, not an individual.
