Embedded Software Development
We develop reliable, efficient, and scalable embedded software across a wide range of platforms from bare-metal microcontrollers to embedded Linux and Android-based systems. Our expertise covers everything from low-level driver development and real-time control loops to full-stack integration with mobile apps, cloud platforms, and OTA infrastructures. Whether you're building a sensor node, industrial controller, smart appliance, or multimedia system, we engineer embedded software that is robust, secure, and production-ready.
KEY HIGHLIGHTS
Bare-Metal & RTOS Firmware
Development of firmware for ARM Cortex-M, RISC-V, and proprietary MCUs using bare-metal or RTOS platforms like FreeRTOS, Zephyr, and ThreadX. We implement deterministic control loops, ISR handling, and event-driven multitasking for real-time reliability.
Peripheral Driver Development
Register-level drivers for I2C, SPI, UART, CAN, USB, PWM, ADC, DMA, and GPIO interfaces. Optimized for speed, low latency, and memory efficiency with modular APIs for reusability and portability across platforms.
Power Optimization & Sleep Strategies
Advanced power management for battery-based devices using dynamic frequency scaling, deep sleep modes, and sensor-triggered wake-ups. Firmware is tuned to achieve energy efficiency for wearables, IoT nodes, and portable systems.
Bootloaders & OTA Update Frameworks
Secure bootloaders with USB, UART, SD card, or wireless update support. We build OTA systems featuring rollback protection, version tracking, and cryptographic validation for safe and scalable deployments.
Embedded Linux Development
Complete board bring-up with kernel configuration, device tree setup, and custom driver development. Includes root filesystem tuning, middleware integration, and service management using systemd.
