Embedded-Temperature-Controlling-System

This system is designed to provide a temperature controlled functionality with some timing constraints.
The system provides the ability to reach a targeted temperature requested by a user interface.
It provides information for the user about the system state, the current temperature and the selected set temperature.
It enables the user to calibrate the heater output through a potentiometer interfaced with ADC.

Applied Concepts:

layered architecture.
1. MCAL
2. HAL
3. Service
4. Application
Design Patterns:
- Proxy pattern: all the micro-controller abstraction layer (MCAL) is implemented with a proxy pattern that encapsulates and abstracts the hardware.
- Periodic Polling: the core Scheduler of the main application is implemented with periodic polling pattern
- State Machine: system states are treated as state machine.
Real-time Design Constraints: Some components required periodicity and maximum jitter, such as:
- Temperature sensor update: every 200ms.
- The calibrator update: every 500ms.
- LCD Animation steps: every 100ms.
- Heating checker: checks if the system doesn't reach the targeted temperature for 3 consecutive minutes.
- Jitter is assumed 10% of periodicity of each component.
