ECPC Competition Problem Solutions - NRW 2024

This repository contains solutions to problems tackled during the NRW (National Robotics Weekend) competition, the opening event of the Eastern Collegiate Programming Championship (ECPC). The ECPC is a prestigious programming competition for university students in Eastern Europe.

Focus:

These solutions are specifically designed for use with STM32CubeIDE, a popular development environment for embedded systems utilizing STM32F407VG microcontrollers.

Problem Folders:

Each problem addressed in the NRW competition has its own dedicated folder within this repository. Folder names directly correspond to the problem number.

Problem Structure:

Within each problem folder, you'll find:

• Code Files (Core/These files contain the source code for the implemented solution, specifically designed for use with STM32CubeIDE.

Problem 4 : Ping Pong Challenge :

This challenge introduces basic communication between two microcontrollers (MCUs) using UART (Universal Asynchronous Receiver Transmitter).

Goal: Develop a program for the MCUs that enables them to exchange "PING PONG" messages via UART.

Requirements:

• Two-way communication:
  • Upon receiving "PING," an MCU responds with "PONG."
• Initiation:
  • One MCU randomly sends "PING" on startup to initiate the exchange.
• Program Identicality:
  • Both MCUs run the same program, acting as transmitter or receiver dynamically.
• Non-blocking communication:
  • The program shouldn't halt while waiting for messages.
• Communication indication:
  • Implement logging (debugger monitor/UART/Logic Analyzer) or an LED blink to confirm communication and program functionality.

Hint: Introduce a random delay at startup to ensure one MCU sends "PING" before the other.

This challenge lays the foundation for building more complex communication protocols between MCUs.

Getting Started:

1. Clone the Repository:

   Use the following command to clone this repository to your local machine:

   git clone https://github.com/bnina-ayoub/ECPC-Solutions.git

2. Open in STM32CubeIDE:

   • Launch STM32CubeIDE.
   • Navigate to File > Open Projects from File Systems.
   • In the import dialog, select the root folder of your cloned repository.
   • Click Finish.

   STM32CubeIDE will import the project structure, allowing you to explore and work with the provided solutions.
