THE CHALLENGEGetting STM32 Firmware Right at Scale Is Harder Than It Looks
Writing firmware that works on a dev board is one thing. Shipping firmware that runs reliably across thousands of production units, handles edge cases gracefully, updates safely in the field, and meets power budgets on battery devices is a completely different challenge. We have built production STM32 firmware for over 40 product programs, and we bring that experience to every engagement.
MCU FAMILIES WE WORK WITH
Deep Experience Across the STM32 Portfolio
STM32F4
High PerformanceOur go-to for applications that need raw processing power. Motor control, audio processing, and complex signal chains. Cortex-M4 with FPU, running up to 180 MHz with rich peripheral sets.
Common use cases: Motor drives, audio systems, industrial controllers, data loggers
STM32G4
Mixed SignalPurpose-built for analog-heavy applications. We use G4 extensively in power conversion, battery management, and precision measurement systems. The integrated comparators and op-amps reduce external component count significantly.
Common use cases: EV charging, battery management, digital power supplies, sensor hubs
STM32H7
Dual Core PerformanceWhen your application demands serious compute on the MCU itself. Dual-core Cortex-M7/M4 running at 480 MHz. We deploy H7 in applications with graphical displays, complex protocol stacks, or on-device ML inference.
Common use cases: HMI displays, gateway devices, edge inference, high-speed data acquisition
STM32L4
Ultra Low PowerBattery-powered products are where L4 shines. We engineer firmware that takes full advantage of the low-power modes, achieving years of battery life on coin cells. Every microamp matters in these designs.
Common use cases: Wearables, environmental sensors, asset trackers, medical devices
CORE CAPABILITIES
What We Build for STM32 Projects
Peripheral Driver Development
We write production-grade drivers for SPI, I2C, UART, CAN, ADC, DAC, and DMA. Every driver is built with proper error handling, timeout management, and DMA integration where it matters for throughput.
RTOS Integration
We integrate FreeRTOS and Zephyr into STM32 projects with proper task design, inter-task communication, and priority management. Our RTOS implementations are tested under load with worst-case stack analysis.
Bootloader Development
Custom bootloaders for field updates over UART, CAN, USB, or BLE. We build secure boot chains with firmware signature verification, dual-bank fallback, and encrypted image transport.
Power Optimization
We profile and optimize power consumption at the firmware level. Sleep mode management, peripheral clock gating, wake-up source configuration, and current profiling with bench-level measurement tools.
Hardware Abstraction Layers
We build HAL layers that decouple application logic from specific STM32 peripherals. This gives you portability across MCU families and makes unit testing on host machines practical.
Testing and Debugging
We work with STM32CubeIDE, ST-Link, and J-Link for development and debugging. Our firmware projects include unit tests, integration tests on hardware, and automated regression testing in CI pipelines.
INDUSTRIES
