Linux powers everything from routers and EV chargers to drones, cameras, industrial machines, and the modern edge AI stack. But behind every peripheral that just works lies a device driver, the thin layer of software that lets hardware talk to the Linux kernel. For new embedded engineers, Linux device drivers
A technical guide to shrinking IoT telemetry without breaking edge systems or cloud pipelines. IoT and embedded systems generate telemetry that overwhelms traditional networks. Sensor readings, actuator states, health logs, diagnostics, and event traces strain wireless bandwidth, burn through MCU flash from local buffering, and stress cloud ingestion pipelines. At
Many embedded systems behave flawlessly during development. They pass unit tests, survive stress testing, and run reliably in controlled environments. Once deployed in the field, though, they occasionally stop responding with no diagnostic trace, no crash logs, no core dumps, no kernel panic. The device simply appears frozen. In real-world
When working with STM32 microcontrollers and external memory configurations, few things are more frustrating than STM32CubeProgrammer refusing to recognize a carefully crafted external memory loader. We ran into exactly this, and the fix revealed some genuinely useful insight into how STM32's toolchain parses external memory loader files. When
Product families rarely run on a single RTOS. A hardware platform might ship as a bare-metal variant for simple, resource-constrained nodes and a FreeRTOS-based SKU for feature-rich devices, each with different constraints, scheduling guarantees, and memory layouts. Traditionally, supporting multiple RTOSes forces teams into separate repositories, linker scripts, build configurations,
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 running continuously under diverse workloads, so memory allocation isn't a theoretical concern, it defines real-world reliability
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, and the Yocto Project solves this by giving you a structured framework to build a Linux system exactly as big as it
Hoomanely is a deep-tech hardware startup building intelligent IoT systems designed to be reliable, predictable, and humane in how they interact with users. Our engineering philosophy centers on robust embedded design, modular hardware pipelines, and rapid prototyping without sacrificing stability. In our early hardware development cycles, the Raspberry Pi Compute
The Microchip MCP2518FD is a popular external CAN-FD controller that interfaces with the host MCU over SPI. It performs well under controlled conditions, but its field reliability comes down almost entirely to the quality of the host-side driver. This post documents technical findings, failure signatures, and recovery patterns validated through
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,
