Make Hardware Do the Right Thing With Embedded Systems & Firmware
A circuit board is only the beginning. Firmware makes devices read sensors, control equipment, communicate securely, and respond when the real world behaves unexpectedly. SDI develops embedded software that connects hardware functions to reliable product behavior.
Firmware That Runs the Product
Does your device work in a demo but fail under real conditions?
Timing issues, unstable drivers, memory limits, dropped connections, and power drains can derail a device after the prototype looks promising. SDI designs embedded application logic, peripheral drivers, communications, startup behavior, diagnostics, and error recovery around the product’s operating requirements.
We work across hardware and software boundaries to make the device predictable, maintainable, and practical to test.
Embedded software and product engineering support is available at $35/hour for defined work.
Modern Embedded Platforms
Which firmware technologies actually fit your hardware?
Depending on the application, the stack may include C/C++, carefully scoped Rust, bare-metal development, FreeRTOS or Zephyr RTOS, embedded Linux or Yocto, and platforms built around STM32, ESP32, or Nordic nRF devices. The right choice depends on timing, power, memory, radio support, and long-term maintenance.
For connected products, secure boot, device identities, signed over-the-air updates, debug access control, and reproducible builds should be considered early—not bolted on after release.
Firmware Built for Real Devices
What should embedded software handle well?
Good firmware turns hardware capabilities into dependable behavior users rarely have to think about.
Drivers & Hardware Control
RESPOND RELIABLY
Read sensors, manage peripherals, control actuators, and coordinate tasks with the right timing and fault handling.
Connectivity & Updates
KEEP DEVICES CURRENT
Implement supported wireless or wired protocols, remote diagnostics, and secure update paths as the product requires.
Edge Intelligence
ACT LOCALLY
Evaluate efficient on-device inference, signal processing, or anomaly detection when privacy, latency, or connectivity matter.
Firmware Lifecycle & Quality
How do you keep firmware dependable beyond the first release?
SDI can establish versioned builds, hardware-in-the-loop test plans, watchdog and recovery strategies, logging, and release procedures tied to device revisions. For suitable hardware, TinyML or optimized ONNX/TensorFlow Lite models can add local intelligence without requiring every decision to travel to the cloud.
The focus stays on measurable device requirements, not adding unnecessary software complexity.
