Embedded Systems Development Services
Embedded systems and embedded firmware development by an engineering team that speaks silicon — from bare-metal C to RTOS-based products.
What embedded systems with CodeCaracal includes
Embedded systems development is firmware written close to the silicon: bare-metal C, RTOS-based applications, device drivers, bootloaders and power management, with kilobytes of RAM and no operating system to hide behind. Getting it wrong surfaces months later as field failures, battery drain or security holes.
Our embedded engineers work on STM32, ESP32, Raspberry Pi RP2040 and custom MCU platforms. We treat power budgets, watchdog design, hardware-in-the-loop testing and secure firmware updates as the baseline — not extras. We also review schematics and layouts so the firmware and hardware agree before you spin a board.
Embedded systems & firmware development services
Types of projects we support
Embedded Systems covers more than one shape of project. These are the engagements we take on most often.
Industrial controllers
Firmware for PLC-adjacent and Modbus-based equipment with deterministic timing.
Medical and safety-adjacent devices
Firmware written with certification constraints and documentation in mind.
Battery / energy-harvesting devices
Sub-microamp sleep design and power-optimised firmware for multi-year life.
Custom board bring-up
First boot, peripheral validation, driver development and production test support.
Legacy firmware rescue
Auditing and fixing inherited firmware for memory safety, reliability and security.

Frequently asked questions
Practical answers to the questions clients ask before starting a embedded systems project.
What microcontrollers do you develop for?+
STM32 (all major families), ESP32 and ESP8266, Raspberry Pi RP2040/Pico, nRF52, and common PIC/AVR parts. We also develop for custom ASIC-adjacent MCU platforms on request.
Do you write firmware for products that need certification?+
Yes — we design with FCC, CE, and safety-critical constraints in mind, keep the documentation auditors need, and support hardware-in-the-loop evidence for compliance.
Can you optimise an existing firmware codebase?+
We regularly audit inherited firmware for power consumption, memory safety, boot reliability and security, then fix the issues that would otherwise surface in the field.
What is the difference between bare-metal and RTOS firmware?+
Bare-metal firmware runs a single main loop and is ideal for simple, deterministic devices. An RTOS (FreeRTOS, Zephyr) lets you split work into scheduled tasks with safe inter-task communication — essential when firmware juggles radios, sensors and control loops. We choose based on your complexity, not fashion.
Do you review our hardware schematics and layout?+
Yes — firmware and hardware must agree before you spin a board. We review schematics and layouts for power integrity, decoupling, boot configuration and peripheral conflicts, and we flag issues before they become a PCB revision.
Can you work with a hardware team that is not CodeCaracal?+
Yes. We regularly join projects where another firm designed the board. You share schematics and the target MCU, and we write, test and debug the firmware against the real hardware.
