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
Have you ever wondered how your pet's GPS tracker knows whether they're running, resting, or digging in the backyard? Or why sometimes the tracker seems to lose accuracy after a few weeks of use? The secret lies in a sophisticated component called an Inertial Measurement Unit,
At Hoomanely, we set out to build connected pet products that could genuinely understand pet behavior and health through multiple sensors working together. Trackers needed to monitor activity, detect vocalizations, track location, and communicate over long distances. Smart bowls needed to measure food consumption precisely, detect presence, capture video, and
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
Implement secure BLE L2CAP CoC streaming with Flutter. Learn dynamic PSM, CoC setup on iOS/Android, and high-speed data over BLE.
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
