Embedded Systems & Firmware Engineering Services
Reliable smart hardware requires rock-solid firmware that never freezes, leaks memory, or drains batteries prematurely. Exelon Circuits architects low-power embedded software and RTOS firmware for industrial, medical, and consumer electronics.
From bare-metal C/C++ drivers on STM32 and ESP32 microcontrollers to secure bootloaders and reliable wireless communications, our Surathkal engineering lab delivers certified, production-ready embedded firmware.
Embedded engineering capabilities
Comprehensive technical solutions engineered for security, reliability and measurable business outcomes.
Microcontroller Firmware (STM32, ESP32, nRF52)
Writing memory-safe, optimized bare-metal C and modern C++ firmware tailored to silicon register architectures.
Real-Time Operating Systems (FreeRTOS, Zephyr)
Structuring multi-threaded task scheduling, mutex synchronization, and deterministic interrupt handling.
Ultra-Low Power & Sleep Optimization
Configuring deep sleep modes and sensor wake-on-interrupt triggers for multi-year battery lifespans.
Secure Boot & Flash Encryption
Implementing hardware root-of-trust, firmware signature verification, and anti-tamper protections.
Fail-Safe Over-the-Air (OTA) Bootloaders
Building dual-partition flash memory architectures that automatically roll back if new firmware fails verification.
Industrial Sensor Bus Protocols
Programming fault-tolerant communication drivers for CAN 2.0B/CAN-FD, Modbus RTU/TCP, RS-485, and UART.
Wireless RF Stacks (BLE, LoRaWAN, Wi-Fi)
Integrating Bluetooth Low Energy GATT profiles, LoRaWAN Class A/C stacks, and Wi-Fi provisioning.
Automated Hardware-in-the-Loop (HIL) Testing
Validating edge cases with automated stimulus injection to catch corner-case memory faults before manufacturing.
