A defined firmware architecture and delivery plan
05 / Embedded systems
Embedded Firmware.
Built around the outcome.
ExaCkt develops embedded software around the actual product behaviour: reliable boot, peripherals, communications, data handling, diagnostics, and a controlled handover path.

THE DELIVERY OUTCOME
Board bring-up, drivers, and application behaviour
Validation notes, build instructions, configuration notes, and release artefacts
WHAT EXACKT CAN COVER
The work is clear.
The decisions are visible.
Every engagement is tailored to the brief, but the work is always organised around tangible engineering outputs and a transparent review path.
Board bring-up
Initial hardware validation, boot flow, clocking, interfaces, and diagnostic hooks for a new or existing board.
Product behaviour
Sensor acquisition, control logic, user interfaces, storage, alarms, communications, and device state handling.
Validation, connectivity and release
Wi-Fi, BLE, cellular, MQTT, Modbus, CAN, OTA strategy, fault handling, configuration, and documented firmware releases.
TARGET PLATFORMS & INTERFACES
The right runtime
for the real device.
We choose the platform around the product’s operating environment, compute needs, connectivity, power budget, lifecycle, and integration requirements—not a one-size-fits-all board.
Arduino & AVR
Fast prototypes, simple controls, sensors, and compact devices.
ESP32 & ESP8266
Wi-Fi, BLE, connected sensors, local interfaces, and OTA-ready products.
STM32 & ARM Cortex-M
Production controllers, motor control, industrial interfaces, and performance-critical work.
Raspberry Pi & Embedded Linux
Gateways, edge applications, camera systems, HMI, and networked products.
Nordic & low-power wireless
BLE products, battery-first devices, wearables, and wireless sensors.
Industrial device interfaces
CAN, Modbus, RS-485, UART, SPI, I²C, GPIO, and field integration.
LANGUAGES & ENGINEERING STYLE
Code that belongs
to the hardware.
Firmware is engineered against the timing, memory, interfaces, and failure modes of the physical device. The implementation can range from lightweight bare-metal control to Linux-based edge applications.

WHAT WE CAN DELIVER
Firmware in the form
your product needs.
Engagements can cover one defined layer or a complete path from first board power-on through released firmware and integration documentation.
Board bring-up
Boot, clocks, pins, power states, peripherals, diagnostics, and first-hardware validation.
Product firmware
Device behaviour, control logic, sensing, displays, storage, state management, and error handling.
Connected devices
Wi-Fi, BLE, cellular, MQTT, HTTP APIs, local provisioning, and telemetry integration.
Firmware releases
Build artefacts, configuration, update strategy, release notes, and deployment guidance.
CONNECTED FIRMWARE
From local sensor data to a reliable connected product.
We can scope provisioning, wireless connection, messaging, local storage, retries, safe update paths, and operational diagnostics around the conditions your device will actually face.

HOW THE ENGAGEMENT MOVES
A deliberate path
from brief to delivery.
We establish the technical and commercial route before work begins, then keep progress connected to the decisions that matter.
Define behaviour
We translate product scenarios into device states, interfaces, priorities, and measurable acceptance conditions.
Plan the firmware
The technical approach covers platform choice, dependencies, interfaces, testing approach, and delivery milestones.
Build and integrate
Firmware is developed against target hardware or a defined integration environment, with regular build reviews.
Validate and hand over
We validate agreed behaviours and deliver release artefacts, setup instructions, and technical notes.
REAL-WORLD FIRMWARE APPLICATIONS
Firmware that holds up
outside the lab.
The defining question is not just what the code does—it is what the device must keep doing when power, networks, sensors, or users behave imperfectly.

EV charging controller
A charging-product team needs dependable session control, status indication, safety interlocks, and remote diagnostics across a changing electrical environment.
- Charge-state and safety-interlock firmware
- Meter, relay, display, and connector interfaces
- Fault logging, recovery behaviour, and field diagnostics
HAVE A DEVICE BEHAVIOUR TO DEFINE?
Bring the operating conditions.
We’ll build the firmware path.
Share the device, interfaces, target platform, prototype status, and field conditions. ExaCkt will turn them into a scoped firmware delivery plan.
Discuss your requirement →IS THIS THE RIGHT START?
This service is useful when you need:
✓New boards requiring first firmware
✓Connected IoT and industrial devices
✓Firmware modernisation and interface integration
✓Prototype firmware that needs validation and a controlled production path
COMMON QUESTIONS
Before you begin.
A short consultation is the fastest way to establish whether this service is the right starting point.
Which platforms can you work with?+
The exact platform is selected during scoping. Common engagements involve MCU-based products, embedded Linux systems, connected gateways, and industrial interfaces.
Can firmware begin before the final PCB arrives?+
Often yes. We can plan software behaviour and work against development boards, simulators, or interface contracts while the target hardware is being prepared.
