LED Stock Ticker on Raspberry Pi

This project is a DIY real-time LED stock ticker display, inspired by similar products available on platforms like Etsy. The project leverages a Raspberry Pi, a 64x32 RGB LED matrix, and financial data APIs to deliver up-to-the-minute price updates for various assets, including stocks, cryptocurrencies, ETFs, forex pairs, indices, and commodities.

Overview

The LED stock ticker display is designed to visually present real-time financial data on a bright and colorful RGB LED matrix. It’s powered by a Raspberry Pi and features a multi-threaded system for efficient data handling and smooth display updates. The system is capable of rendering asset logos, symbol names, daily percentage changes, and mini-price charts.

Features

• Real-Time Data Updates: Utilizes WebSockets to fetch live data from financial APIs like FinnHub.
• Support for Multiple Asset Classes: Display prices and charts for stocks, ETFs, cryptocurrencies, forex pairs, indices, and commodities.
• Customizable Display: Choose between displaying asset logos with price info or full 64-column price charts.
• Multithreading: Ensures smooth and responsive operation, even with multiple data streams.
• Data Storage: Price data is stored in a PostgreSQL database, enabling historical analysis and charting.
• Web-Based Control: Configure the ticker, manage API keys, and customize subscriptions via a web interface.

Hardware Requirements

• Raspberry Pi 4B
• Adafruit 64x32 RGB Matrix
• Adafruit Bonnet
• Power Supply

Configure using website

To control the configuration, obtain the API key and set up subscriptions, logos, and API names using stock-ticker-remote

Getting Started

1. Clone the Repository:

   git clone https://github.com/yahnyshc/stockTicker
   

2. Setup the Environment:

Navigate to the Scripts/ directory and run the appropriate setup script for your OS to generate project files.

4. Connect Hardware:

Connect the RGB LED Matrix to the Raspberry Pi 4 GPIO pins as per the rpi-rgb-led-matrix library instructions.

Don't forget to install the necessary Adafruit-Hat drivers.

5. Configuration:

• Create a config file named config.cfg in the root directory with the following contents:

  API_Token=<FinnHub API Key>
  Control_API_Token=<API Key obtained from stock-ticker-remote.link> (optional)
  
  # This doesn't have to be configured if Control_API_Token is specified.
  Subs_list= BTC NVDA 
  Api_Subs_list = COINBASE:BTC-USD NVDA
  Logo_Subs_list = BTCUSD NVDA
  
  Logo_Size=23
  
  # Determines whether to display logos or instead display a full 64-column price chart.
  Render_Logos=true
  ...
  # See Config.cpp to find out about more config options
  

6. Build and Run:

   The project follows Core - App architecture.

   make
   ./Binaries/<OS>/Debug/App/App
