Embedded Firmware &
Software Engineering,
with the hardware

CRATUS develops embedded firmware for Arm Cortex-M microcontrollers and embedded Linux processors. That covers drivers and board support packages, bootloaders, bare-metal and RTOS firmware, communication stacks, low-power modes, secure boot and over-the-air updates, plus the tests and documentation to maintain it.

CRATUS builds the software around connected devices: edge data pipelines (including ASSET-Rx EDGE), cloud dashboards and device management, REST and MQTT APIs, desktop and mobile commissioning apps, AI models, and end-of-line test and calibration software.

Yes. We bring up firmware on existing boards, port code to new microcontrollers, and take over or stabilize existing codebases. A code and architecture review comes first so we can tell you what to keep, fix or rewrite.

Yes. CRATUS works as a Team-in-a-Box: electronics, PCB layout, FPGA, mechanics, firmware and software. Hardware and firmware built together means optimized timing, lower latency and faster iterations, with no hand-off delays between vendors.

From Arm Cortex-M microcontrollers to NVIDIA Jetson-class single-board computers. We select the platform for your requirements on performance, power, cost and supply, or work with the one you already use.

Bare-metal suits small, strictly deterministic devices. An RTOS such as FreeRTOS or Zephyr suits firmware with several concurrent tasks and communication stacks. Embedded Linux suits application processors that need networking, storage, displays or AI workloads. We recommend one after reviewing your requirements.

CAN and CAN FD, CANopen, SAE J1939, MODBUS RTU/TCP, RS-485, IO-Link, Bluetooth, Wi-Fi, LoRa, NB-IoT, MQTT and OPC UA. We also write protocol bridges and gateways when two systems don’t share a protocol.

With a secure bootloader, signed images, A/B partitions and automatic rollback if an update fails, plus staged roll-outs across a device fleet. Updates are versioned and logged, so you always know what is running in the field.

Yes. We build device management, dashboards, alerts and data pipelines, the APIs that connect them, and desktop or mobile apps for commissioning and service. ASSET-Rx EDGE and INTERCAL8 EMS give many projects a proven starting point.

Yes, over OPC UA, MQTT, MODBUS TCP and REST APIs, to your SCADA, historian, MES or ERP and to your choice of cloud or on-premises servers.

Yes. Compact anomaly-detection and classification models run on Cortex-M microcontrollers next to the sensor; the INTERCAL8 ICL8-TM116, for example, computes predictive thermal insight on-device. Vision and LiDAR workloads run on NVIDIA Jetson-class computers.

Yes: model training and evaluation, annotated and ground-truth reference data for machine learning, analytics pipelines, and natural-language interfaces such as the INTERCAL8 AI Assistant, which lets operators manage power hardware in plain language.

Unit tests on the host, hardware-in-the-loop rigs on real boards, static analysis and MISRA C checks, and continuous integration on every change. For production we write end-of-line test software, and we deliver test reports with each release.

Secure boot, signed over-the-air updates with rollback, encrypted transport, unique device identity and least-privilege access, following IEC 62443-4-1 secure development practices.

Send us a message through our contact form with what you’re building, where it will operate and your timeline. We’ll schedule a technical discovery call, then send a scoped, phased proposal, so you can begin with an architecture study or prototype and commit to production later.

Yes. We can own the whole system as a Team-in-a-Box, or take a defined piece (the power stage, the firmware, the cloud pipeline, the AI model) and work inside your repositories, toolchains and design reviews.

Yes. We carry designs from prototype through DFM and DFT reviews, test-fixture and end-of-line test development, pilot builds and full-scale production support.
