QuizBuzzerSystem

This repository holds the code for an advanced quiz buzzer system. More than just knowing who pressed a button first, we can tell the exact reaction times etc.

Setup

For the web-server to run, you need to install a library for the audio dependency.

sudo apt-get update && sudo apt-get install -y libasound2-dev node-typescript

For the devboard, you need to configure a local-link ethernet connection with you laptop's IP fixed to 192.168.100.2.

devboard

The devboard crate is built for the STM32H745I-DISCO. It contains the code which will run on the board.

web-server

The web-server provides both the backend with which the board communicates and hosts the frontend that users interact with.

Running the web server

# Currently, you need to start from this path due to hardcoded paths.
cd web-server

# Start with default/dev config
cargo run --release

# Start with production config
RUN_MODE=prod cargo run --release

In the production config, you can navigate to http://192.168.100.1:8000/ to see the frontend.

VS Code

For the rust-analyzer to work in VS Code in the devboard folder, we need to add custom settings in Ctrl+Shift+P -> Preferences: Open User Settings (JSON).

{
  "rust-analyzer.checkOnSave.allTargets": false,
  "rust-analyzer.checkOnSave.extraArgs": ["--target", "thumbv7m-none-eabihf"]
}
