The Debouncing Pattern in Embedded Systems
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
