Users can update text, position, font size, color, and background settings remotely through a web form. The display updates dynamically based on user inputs.\n\n## ⚠️ Disclaimer\nThis code is **not original** and is a **compilation of various resources** found online. It has been modified and combined to achieve the desired functionality. If you recognize portions of this code from other sources, credit is due to the respective authors.\n\n## Features\n- **Wi-Fi Connectivity**: ESP32 connects to a specified SSID.\n- **Web-based Control Panel**: Users can modify the text displayed on the e-paper screen.\n- **Customizable Display Settings**:\n  - Text Content\n  - Font Size (9pt, 12pt, 18pt)\n  - X/Y Positioning\n  - Text \u0026 Border Color (Black, Red, White)\n  - Background Color\n- **Low-Power E-Paper Display**: Text remains visible even after power loss.\n\n## Setup Instructions\n### **1. Hardware Requirements**\n- ESP32 microcontroller\n- E-Paper Display (`GxEPD2_290_C90c`)\n- Wi-Fi Network\n\n### **2. Libraries Required**\nMake sure you have installed the following libraries in the **Arduino IDE**:\n- `WiFi.h` (for Wi-Fi connectivity)\n- `WebServer.h` (to host the web interface)\n- `GxEPD2_3C.h` (for e-paper display control)\n- `Fonts/FreeMonoBold9pt7b.h`, `Fonts/FreeMonoBold12pt7b.h`, `Fonts/FreeMonoBold18pt7b.h` (for font rendering)\n\n### **3. Code Upload**\n1. Modify the Wi-Fi credentials in the code:\n   ```cpp\n   const char* ssid = \"YourSSID\";\n   const char* password = \"YourPassword\";\n   ```\n2. Compile and upload the code to the ESP32 using **Arduino IDE**.\n3. Open the **Serial Monitor** at `115200 baud` to find the assigned **IP address**.\n4. Enter the IP address in a browser to access the web interface.\n\n## Web Interface\nThe web server allows users to modify the text and display properties. Changes are sent to the ESP32 and immediately reflected on the e-paper display.\n\n## ⚠️ Web Server Status: **Test Mode**\nThe current implementation is in **test mode** and **should not be used in production** without modifications.\n- **No authentication**: Anyone on the network can access and modify the display.\n- **No input validation**: Users can input invalid values, potentially causing errors.\n- **Limited error handling**: The system does not handle incorrect inputs gracefully.\n\nTo improve security and functionality, consider implementing:\n- User authentication (e.g., login system)\n- Input validation (limit string length, prevent bad values)\n- Error handling (prevent crashes and undefined behavior)\n\n## Known Issues \u0026 Improvements\n- The web interface UI is minimal and could be enhanced with better styling.\n- ESP32 memory constraints may limit large text updates.\n- Some e-paper displays may require different pin configurations.\n\n## Contributions\nIf you wish to improve or modify this project, feel free to **fork the repository** and submit a pull request.\n\n## License\nThis project is released under the **MIT License**. However, since the code is a compilation from multiple sources, please ensure you comply with any applicable licenses from original authors.\n\n---\n🚀 **Happy Coding!** 🚀\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsurin-learning-lab%2Fe-paper_display","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsurin-learning-lab%2Fe-paper_display","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsurin-learning-lab%2Fe-paper_display/lists"}
