Alarming System for LPC1768 using FreeRTOS

This project is an alarming system built for LPC1768 using FreeRTOS and developed using KeilStudioCloud IDE. It provides the following functionalities:

• Sensor monitoring service (working in a periodic way and on demand, and with the capability of storing collected data and with the possibility of handling alarm situations).
• Clock service (to provide user meaningful time (wall clock) and to allow clock alarm management).
• Processing of information.
• Device actuation (to be handled by a resource manager task or in a distributed way).
• User interface (console).

Requirements

• LPC1768 microcontroller
• FreeRTOS
• KeilStudioCloud IDE

Installation and Usage

1. Clone this repository to your local machine.
2. Open the project in KeilStudioCloud IDE.
3. Build and flash the project to your LPC1768 microcontroller.
4. Connect to the microcontroller using a terminal emulator.
5. Use the provided command line functionalities to interact with the alarming system.

Connecting to the board

You are free to use any terminal emulator of your choice. Despite that, here are some steps in order to connect to the board using Putty:

1. Select the device Serial line (on linux it is usually /dev/ttyACM0)
2. Match Baud in the Speed input box
3. Select Serial under Connection Type
4. (Optional) Go to Terminal settings and check Force on in the Local echo, this will allow you to verify your input integrity
