FreeRTOS Queues on STM32: Copy Semantics, the ISR Boundary, and the Anti-Patterns That Cause Silent Data Loss
Most FreeRTOS queue tutorials stop at xQueueSend and xQueueReceive — the two calls that were never the hard part. They show you a producer task,
Event-Driven Firmware Architecture
Most write-ups on event-driven firmware stop at the conceptual layer: events decouple modules, a queue holds them, a dispatcher routes them. That part is easy
