Introduction Mechanical switches, buttons, and some sensors don’t produce clean, instantaneous transitions between ON and OFF states. Instead, they generate a series of rapid, unpredictable

The Observer Pattern in Embedded Systems
Introduction In many embedded systems, one hardware event or sensor reading must be used by multiple parts of the system. For example: If each module
The Mediator Pattern in Embedded Systems
Introduction Complex embedded systems quickly develop messy interaction graphs: sensors trigger logic that wakes radios, which log to flash, while power management tries to keep
The Hardware Proxy Pattern in Embedded Systems
Introduction Accessing hardware in embedded systems is notoriously tricky. Beyond the raw registers and memory-mapped I/O, developers often face additional complexities: compression, encoding, DMA orchestration,
