In modern embedded systems, whether high-speed vision sensors, multi-channel audio acquisition, or edge ML inferencing, throughput and latency matter. When you run a full embedded Linux platform but also need real-time data processing, simple threading isn't enough. You have to structure threads, pick the right scheduling policies, bind
In every real-time embedded system, interrupts are where the action begins. Whether it's a camera sensor signaling a frame ready, a CAN packet arriving, or a GPIO line pulsing high, the first code to run is almost always the Interrupt Service Routine. But ISRs should be fast, lightweight,
Building a production-ready camera system with 45 MB/s sustained throughput Direct Memory Access promises zero-CPU data transfers, but poor buffer design can turn that promise into corrupted frames, system crashes, and unpredictable behavior. This post shares hard-won lessons from building Hoomanely's camera module, a dual-sensor system capturing
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
