Firmware Development
Development of low-level software that controls embedded hardware.
What We Do
Firmware is the bridge between the physical hardware and the functional behavior of a product. We develop clean, modular, and well-documented firmware that maximizes hardware capabilities while remaining rock-solid under stress.
Capabilities
- Bare-metal firmware development
- RTOS-based firmware (FreeRTOS)
- Custom bootloaders
- Over-The-Air (OTA) update mechanisms
- Peripheral driver development
- Communication stacks (TCP/IP, MQTT, Modbus)
- Sensor data processing and filtering
- Power management and ultra-low-power firmware
Technologies
Our Engineering Process
- Requirements: Defining state machines and application flow.
- Architecture: Structuring tasks, memory mapping, and interface definitions.
- Module Development: Writing isolated driver and application modules.
- Unit Testing: Verifying logic independently of hardware where possible.
- Integration: Flashing code to target hardware and debugging interfaces.
- Hardware Validation: Stress testing the system in real-world conditions.
- Production: Finalizing release binaries and programming procedures.
Applications
Motor control firmware, sensor data acquisition, communication gateways, industrial automation controllers, and IoT edge devices.
Frequently Asked Questions
Do you write bare-metal code or use an RTOS?
We do both, depending on the complexity of the application. For simple tasks, bare-metal is sufficient. For complex, multi-threaded applications, we typically use FreeRTOS or Zephyr RTOS.
Can you implement Over-The-Air (OTA) updates?
Yes, for connected edge devices (ESP32, Nordic nRF, Cellular/Wi-Fi modules), we routinely implement secure encrypted OTA update mechanisms with dual-bank fail-safe rollback.
Do you write custom peripheral drivers?
Yes, while we leverage vendor HALs where appropriate, we frequently write custom register-level drivers for specialized sensors, displays, or timing-critical interfaces.
How do you handle power optimization in firmware?
We utilize MCU sleep modes, peripheral clock gating, and interrupt-driven architectures to minimize active time and reduce power consumption for battery-operated devices.
Can you fix or optimize existing firmware?
Yes, we can audit existing codebases, identify bottlenecks, fix bugs, and refactor code for better maintainability and performance.
