Building a production-ready camera system with 45 MB/s sustained throughput Direct Memory Access (DMA) 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

Storage wear & tear — practical engineering guide from Ever-bowl’s memory pipeline This post explains how the Ever-bowl platform uses PSRAM as a buffer and a flash-aware firmware stack to extend flash lifetime. It includes concrete implementation pitfalls and solutions, datasheet-backed guidance, and a practical checklist for engineers building similar

A Guide to CAN Controllers, Transceivers, and Bus Configuration Introduction When our team at Hoomanely began developing iot devices for building a pet environment platform, we faced a critical challenge: transmitting high-resolution sensor data between multiple ECUs with microsecond-level timing precision were We needed CAN FD. But here's

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 article explores a sophisticated implementation on the STM32 microcontroller, specifically the STM32H562, which features a dual-bank flash architecture that
