Firmware Development

We have proven experience across several embedded platforms. We primarily work with STM32 (STMicroelectronics) microcontrollers for industrial and automotive applications, ESP32 (Espressif) for IoT and wireless solutions, and Microchip platforms including advanced SoCs like PolarFire SoC (Multi-Core RISC-V + FPGA) for high-complexity applications. The platform choice is made together with the client based on project requirements: performance, power consumption, connectivity, and cost.

Firmware optimizes the microcontroller's resources to ensure real-time responses and reduced power consumption. It is critical in embedded applications where efficiency, reliability, and battery life are priorities. Well-designed firmware manages efficient peripheral drivers, implements power management strategies, and ensures long-term scalability and updatability of the system.

A real-time operating system (RTOS) is recommended when the firmware must handle multiple concurrent tasks with precise timing constraints, such as communications, data acquisition, and actuator control in parallel. For simpler applications or those with strict latency and power consumption requirements, a bare-metal approach can be more efficient and deterministic.

Yes, secure and reliable over-the-air (OTA) firmware update systems can be implemented, particularly useful for IoT devices distributed in the field. The approach includes bootloaders with integrity verification, automatic rollback on failure, and encrypted update packages to ensure process security.

Scalable firmware is designed with a modular architecture, separating hardware (HAL), middleware, and application layers. Security is ensured through verified bootloader mechanisms, encrypted communications, and memory protection. Updatability is implemented via secure update systems (OTA or physical interface) with automatic rollback, enabling bug fixes and feature additions on devices already deployed in the field.
