Embedded Software Development Services
Crunch-IS provides embedded software development services for industrial, IoT, medical, and consumer hardware — scoped around your silicon, your real-time constraints, and the conditions your product will actually face.
Our AI-enabled engineering model runs agents across the software workstreams, so the build moves faster without thinning the team. You get production-ready embedded software, validated on target hardware, from architecture through field deployment.
Benefits of Embedded Software Development
Hardware constraints, timing requirements, and integration dependencies are mapped before code is written — not discovered mid-build, when changing course is expensive.
Parallel testing throughout the build and a scoped mass-production path mean fewer surprises between the prototype and volume production.
Documented architecture, clear abstraction boundaries, and a build environment that transfers reduce the cost of every future change.
HIL testing and a post-deployment hypercare window mean the product performs outside the lab, in the conditions it will actually face.
Need embedded software that holds up outside the lab?
Embedded Software Development Services We Offer
Embedded Software Design and Assessment
Before any code is written, we map your hardware platform, peripheral set, timing requirements, and integration constraints. That assessment drives an embedded software design grounded in what your product actually has to do. The architecture is documented and reviewed before the build starts, so constraints surface in planning rather than mid-project.
Custom Embedded Development
We write embedded software for your specific device, from hardware initialization and peripheral management through application logic and system state control. The choice between bare-metal and RTOS is made during architecture review, driven by your power budget and timing ceiling.
Embedded Software Testing
Embedded software testing here is not a phase bolted on at the end. Unit tests, hardware-in-the-loop validation, and boundary-condition analysis run in parallel with development, so defects are caught and resolved before they propagate into later stages.
MCU Migration and Platform Porting
When a product moves to a different microcontroller — driven by supply chain, cost, or capability — we assess what firmware carries over and what needs rewriting before any code is touched. No assumptions are made about compatibility; driver layers, clock trees, and linker configuration are reviewed first.
Embedded AI Implementation
When the application requires on-device inference, we scope and build the AI integration as part of the embedded software engagement. We cover model optimization, runtime selection, and the hardware requirements that make inference viable within the product’s power and memory budget.
Mass Production Support
When the product moves to volume, we support the full transition: production firmware variants, device programming configuration, and manufacturing test fixture development. The path from prototype to production unit is scoped from the start, not improvised at the end.
Our Capabilities
Native MCU and SoC Development
We write firmware directly against the target silicon — ARM Cortex-M, RISC-V, AVR, and vendor-specific SoC platforms — with direct access to peripherals and full control over execution behavior. This is the right approach when determinism and raw performance can’t be compromised.
RTOS Integration
We implement and tune real-time operating systems — FreeRTOS, Zephyr, ThreadX, and others — for products that need structured task scheduling, concurrent peripheral management, or guaranteed timing windows. RTOS selection follows from your requirements, not a default.
Bare-Metal Development
For products where an RTOS would consume headroom beyond the power budget or latency ceiling, we deliver optimized bare-metal firmware. Bare-metal versus RTOS is a technical decision made during architecture review.
Communication Stacks
We build and validate embedded communication interfaces across the full protocol range: UART, SPI, I2C, CAN, Ethernet, BLE, Zigbee, MQTT, and custom implementations. Each stack is validated against real bus conditions and the actual integration targets your product connects to.
Hardware-in-the-Loop Testing
HIL testing puts the embedded software through simulated electrical and environmental conditions before the device enters production. Failure modes and edge cases are resolved in a controlled setting, where the cost of catching them is still low.
Embedded Linux and BSP Development
When the product requires a full operating system, we handle Board Support Package development, kernel configuration, driver integration, and production image configuration — built and validated against your specific hardware.
AI-Enabled Engineering
AI agents run across the software workstreams — generating boilerplate, expanding test coverage, and keeping documentation current — under senior engineer review at every step. The result is faster delivery of software layers without the quality risk associated with unreviewed automation.
What You Get
A Codebase Your Team Can Own
Firmware is handed over with complete architecture documentation, clear hardware abstraction boundaries, and a build system your engineers can work with from day one. The goal is a codebase your team can extend without reverse-engineering it.
A Build Environment That Transfers
We deliver a fully configured toolchain — compiler settings, linker scripts, dependency management, and CI integration where required — so your team picks up where we left off without reconstructing how the build works.
Faster Delivery Without a Bigger Team
Our AI-enabled build model compresses timelines, so you get working embedded software sooner without paying for a scaled-up delivery team. Senior engineers stay accountable for every output.
A Defined Post-Deployment Period
The engagement doesn’t close at deployment. Every project includes a hypercare window with active monitoring, performance optimization, and rapid response to anything that surfaces in the live environment.

Embedded Software Development FAQ
What is embedded software?
Embedded software is code written for a specific hardware platform — a microcontroller, processor, or SoC — that controls a device’s behavior. It typically runs on an operating system or RTOS and handles the higher-level logic: user interface, connectivity, data processing, and business rules that turn a functioning device into a smart one.
Do you take on mass production for the devices you create?
Yes. When a project moves to volume, we support production firmware variants, device programming toolchain setup, and manufacturing test fixture development. Mass production is planned for during the initial scoping phase.
What is RTOS and why is it important for embedded systems?
An RTOS provides a task-scheduling layer that lets firmware run multiple functions concurrently with deterministic timing guarantees. It’s the architecture you reach for when specific operations must be completed within a fixed time window, and manual interrupt management alone can’t make that guarantee reliably.
What is bare-metal programming?
Bare-metal programming is firmware written directly on the hardware without an OS or scheduling layer. It’s the right approach when the power envelope or latency ceiling leaves no room for OS overhead, provided the team has the systems depth to manage that complexity explicitly.
Why might porting embedded software to a different MCU be required?
The most common drivers are component discontinuation, supply chain pressure, a silicon capability gap the current MCU can’t close, or a product expansion requiring new peripherals. Firmware rarely transfers cleanly between platforms — driver layers, clock trees, and linker configuration all need to be reviewed before migration begins.
What is hardware-in-the-loop (HIL) testing?
HIL testing connects the embedded software under development to a simulation rig that reproduces the electrical signals and environmental inputs the device will see in the field. It lets the team validate edge cases and fault conditions in a controlled environment before any hardware reaches production.
What does embedded AI require from embedded systems?
On-device inference needs sufficient SRAM for activations, flash storage for model weights, and — at higher workloads — a processor with DSP extensions or a dedicated neural processing unit. The firmware must also manage inference latency, power draw during computation, and runtime integration with the rest of the application.
What is the difference between standard software and embedded software?
Standard software runs on hardware with abundant resources and an OS managing the underlying system. Embedded software runs on constrained silicon, explicitly manages hardware peripherals, and treats timing and memory as hard requirements rather than performance considerations.
