Ventilation Project

This project is designed for the NXP LPCXpresso1549 board and implements a system to control a fan and monitor a pressure sensor. The system features an interactive menu navigable via buttons and allows for two operational modes:

Features

• LED & Button Interface: Adjusts fan pressure settings.
• Two Modes of Operation:
  1. Manual Mode – Directly control the fan power.
  2. Automatic Mode – Set a target pressure (in bars), and the system calculates the required fan speed.
• Pressure Sensor Handling: Reads real-time pressure values.
• Blinking LED Feedback: Displays system status without affecting menu navigation.

Hardware Requirements

• Board: NXP LPCXpresso1549
• Components:
  • Fan
  • Pressure Sensor
  • LEDs
  • Push Buttons

Menu Controls

• UP (B1): Move up in the menu / Increase values.
• DOWN (B3): Move down in the menu / Decrease values.
• OK (B2): Select menu item / Confirm action.
• Timeout Handling: If no button is pressed for 10 seconds, the system returns to the main menu.

LED Behavior

• LED blinking is used to indicate system states.
• LED timing is controlled by:
  • Time: How long the LED stays ON (0-200ms, step 20ms)
  • Blank: How long the LED stays OFF (0-1s, step 0.1s)
  • Light: Selects which LED is controlled (0 = none, 1 = red, 2 = green, 3 = blue)

Blinking & Menu Independence

The LED blinking process runs independently of the menu system to ensure uninterrupted navigation while the fan and pressure regulation operate smoothly.

Getting Started

1. Clone the repository:

   git clone https://github.com/Biboulder/Ventilation_project.git

2. Build and flash the firmware onto the NXP LPCXpresso1549 board.
3. Use the buttons to navigate and control the fan or pressure settings.
