Software Requirements¶
The software requirements section refines the high-level system requirements into detailed, implementable specifications for the embedded control system. The BrewMaster Pro 3000 runs on a custom Rust-based embedded platform with real-time capabilities, chosen for its memory safety guarantees, zero-cost abstractions, and excellent embedded systems support. These requirements specify precise timing constraints, control algorithms, and safety-critical behavior that must be implemented in software. Each software requirement is traceable back to one or more system requirements, ensuring complete coverage of customer needs.
The temperature control software shall monitor the water temperature sensor and regulate the heating element to maintain temperature between 85-95°C using PID control. |
The software shall continuously monitor water temperature and trigger an emergency shutdown within 100ms if temperature exceeds 100°C to prevent boiling and potential hazards. |
The software shall implement brew strength selection by controlling the water flow rate and brewing time:
|
The software shall process button inputs with debouncing and trigger appropriate actions (strength selection, start brewing, stop/cancel). |
The software shall continuously monitor the water level sensor and prevent brewing operations when water level is below minimum threshold. |
