When working with STM32 microcontrollers and external memory configurations, few things are more frustrating than STM32CubeProgrammer failing to recognize your carefully crafted external memory loader. We encountered exactly this issue—and the solution revealed fascinating insights into how STM32's toolchain parses external memory loader files. This post chronicles

How Hoomanely Leverages RTOS Abstraction to Build Unified Firmware Across Bare-Metal and FreeRTOS Introduction In modern embedded engineering, product families rarely run on a single RTOS. A hardware platform may ship as a bare-metal variant for simple, resource-constrained nodes and a FreeRTOS-based SKU for feature-rich devices, each with unique constraints,

Hoomanely Context At Hoomanely, our embedded platforms power an ecosystem of modular IoT products where reliability, uptime, and predictability matter more than raw throughput. Our System-on-Module architecture spans sensing, communication and processing nodes, all operating continuously under diverse workloads. Memory allocation is therefore not a theoretical concern. It defines real-world

Introduction Every embedded Linux engineer eventually reaches the same point: the need for a fully customized, lightweight, reproducible Linux distribution. Prebuilt OS images are bloated; build-from-scratch distros are fragile. Yocto Project solves this by giving you a structured framework to craft a Linux system that is exactly as big as

The Microchip MCP2518FD is a popular external CAN-FD controller that interfaces with the host MCU over SPI. While the device performs well under controlled conditions, its field reliability is governed almost entirely by the quality of the host-side driver. This article documents technical findings, failure signatures, and recovery patterns validated

Adaptive sampling turns your wearable into a system that feels alive—delivering the right data at the right moment while preserving battery for when it matters. Instead of locking sensor rates in firmware, we set behavior at the app layer with a small, transparent policy engine. The device advertises capabilities;

In modern imaging pipelines especially those running on edge devices every byte matters. When an embedded system captures images, those images must travel through limited memory, constrained communication buses, and strict power budgets. Large image payloads degrade system performance, slow down recovery pipelines, and create unpredictable behavior. To keep imaging

Real-world lessons from transitioning parallel to serial camera architectures in production embedded systems Imagine this: an industrial vision system built around a high-performance MCU and a 1 MP camera using the traditional parallel interface (DCMI). It worked—until you added thermal sensors, proximity modules, and wireless connectivity to the same

Monolithic firmware scales linearly in features but exponentially in complexity.When building IoT devices that integrate multiple sensors - accelerometers, GPS modules, barometers, LoRa communication, and more firmware projects quickly become unmanageable. A single, monolithic codebase where everything lives in one directory creates several critical issues: Compilation bottlenecks: Change one
