Cortex-M to Linux — engineering notes across the embedded systems stack.
When you're building an on-device image capture pipeline, privacy can't be something you handle later. If a full-frame or identifiable capture ever gets persisted or shipped, even briefly, you've already created a privacy risk and a testing headache. A stronger pattern is making privacy
When you first validate a bursty image pipeline on LittleFS, it usually looks great: average write times stay low, and short tests feel done. Then you run a 6-to-12-hour soak, flash creeps toward full, and suddenly P95/P99 write latency starts spiking. Frames arrive in bursts, your producer thread blocks
When a user picks up your IoT device, they ask three immediate questions without saying a word: is it on, is it working correctly, how much battery is left. At Hoomanely, we answer all three through a single, intelligent interface: RGB LEDs driven by PWM signals. Not as decoration, but
Storage wear and tear: a practical engineering guide from EverBowl's memory pipeline This post explains how the EverBowl platform uses PSRAM as a buffer and a flash-aware firmware stack to extend flash lifetime. It covers concrete implementation pitfalls and solutions, datasheet-backed guidance, and a practical checklist for engineers
A guide to CAN controllers, transceivers, and bus configuration When our team began developing IoT devices for a pet environment platform, we faced a critical challenge: transmitting high-resolution sensor data between multiple ECUs with microsecond-level timing precision. We needed CAN FD. But CAN FD isn't just "CAN,
How dual-bank architecture enables seamless, zero-downtime firmware updates via CAN Firmware updates are crucial for modern embedded systems, enabling remote device maintenance, feature additions, and security patches without physical access. This post covers a production implementation on the STM32H562, which features a dual-bank flash architecture enabling seamless firmware updates through
That ESP32-S3 prototype working perfectly on your desk? It'll brick itself in production. Here's the checklist that separates hobbyists from engineers shipping real products. You've built something magical. Your ESP32-S3 prototype streams 9-axis IMU data flawlessly. The BLE connects every time. Battery lasts for
