DeskTicker

DeskTicker is a compact and customizable stock display designed for a small display module. This project was originally designed for the ESP32-2432S032 board but could be easily adapted to other Arduino compatible displays. It displays current stock prices and daily changes, along with a visual chart of daily data. DeskTicker also includes a user-friendly web interface for managing the list of stocks to display.

 

Features

• Real-Time Price Updates: Displays the current stock price, daily change, and a chart of the stock's daily performance.
• Web Configuration: Easily update the list of stocks to monitor through a hosted web page.
• Customizable: While optimized for the ESP32-2432S032 display, the code can be adapted for other ESP32-based displays.
• Local Data Storage: The historic price data is stored locally on a microSD card to minimize API calls.

Hardware Requirements

• ESP32-2432S032 Display Module (or other compatible display with minor modifications).
• MicroSD Card (no need for a large capcity)
• Power supply

Installation

1. Clone the repository:

   git clone https://github.com/hemingerg1/DeskTicker.git

2. Install VS Code and the Platformio extension if not already installed.

3. Prepare the SD card.

   • Insert the card into a computer and format it as FAT32.
   • Save the /DeskTicker_pio/index.html file to the root directory of the SD card.
   • Insert the card into your display

4. Flash the code to your ESP32 module using PlatformIO:

   • Open the /DeskTicker_pio folder with Platformio.
   • Change timezone information in /DeskTicker_pio/src/main.cpp if not in US EST.
   • Build and upload the code to the ESP32 module.

5. Power on the device and access the web interface to configure the stocks to display.

   • On the first boot the settings screen will be displayed where you need to enter your Wi-Fi credentials.
   • Once connected to Wi-Fi it will show the address where you can access the webpage to enter the tickers you want to display.

Usage

1. Power on the device: The DeskTicker will connect to the configured Wi-Fi network.
2. Access the web page: Use a browser to navigate to the device's IP address. The address is displayed at the top of the settings screen.
3. Configure stocks: Add or remove stocks to customize the display.
4. View the display: Stock data and charts will be updated automatically.

Adapting to Other Displays

DeskTicker is designed for the ESP32-2432S032 display but should be easily adapted to other displays. If using another Sunton display simply download the json file for your board from platformio-espressif32-sunton and save it in the /DeskTicker_pio/boards folder. Then update the platformio.ini file to include the new board. If using a different board you will need to provide your own appropriate libraries and drivers.

Software Requirements

The project requires the following software dependencies:

• Platformio: used for compiling and flashing the firmware
  • Libraries:
    • rzeldent/esp32_smartdisplay
    • ottowinter/ESPAsyncWebServer-esphome
    • fbiego/ESP32Time
    • bblanchon/ArduinoJson
• Squarline Studio: used to create and modify the UI
