Add connect to Wifi and File Manager Webserver (#41) ## Summary - **What is the goal of this PR?** Implements wireless EPUB file management via a built-in web server, enabling users to upload, browse, organize, and delete EPUB files from any device on the same WiFi network without needing a computer cable connection. - **What changes are included?** - **New Web Server** ([`CrossPointWebServer.cpp`](src/CrossPointWebServer.cpp), [`CrossPointWebServer.h`](src/CrossPointWebServer.h)): - HTTP server on port 80 with a responsive HTML/CSS interface - Home page showing device status (version, IP, free memory) - File Manager with folder navigation and breadcrumb support - EPUB file upload with progress tracking - Folder creation and file/folder deletion - XSS protection via HTML escaping - Hidden system folders (`.` prefixed, "System Volume Information", "XTCache") - **WiFi Screen** ([`WifiScreen.cpp`](src/screens/WifiScreen.cpp), [`WifiScreen.h`](src/screens/WifiScreen.h)): - Network scanning with signal strength indicators - Visual indicators for encrypted (`*`) and saved (`+`) networks - State machine managing: scanning, network selection, password entry, connecting, save/forget prompts - 15-second connection timeout handling - Integration with web server (starts on connect, stops on exit) - **WiFi Credential Storage** ([`WifiCredentialStore.cpp`](src/WifiCredentialStore.cpp), [`WifiCredentialStore.h`](src/WifiCredentialStore.h)): - Persistent storage in `/sd/.crosspoint/wifi.bin` - XOR obfuscation for stored passwords (basic protection against casual reading) - Up to 8 saved networks with add/remove/update operations - **On-Screen Keyboard** ([`OnScreenKeyboard.cpp`](src/screens/OnScreenKeyboard.cpp), [`OnScreenKeyboard.h`](src/screens/OnScreenKeyboard.h)): - Reusable QWERTY keyboard component with shift support - Special keys: Shift, Space, Backspace, Done - Support for password masking mode - **Settings Screen Integration** ([`SettingsScreen.h`](src/screens/SettingsScreen.h)): - Added WiFi action to navigate to the new WiFi screen - **Documentation** ([`docs/webserver.md`](docs/webserver.md)): - Comprehensive user guide covering WiFi setup, web interface usage, file management, troubleshooting, and security notes - See this for more screenshots! - Working "displays the right way in GitHub" on my repo: https://github.com/olearycrew/crosspoint-reader/blob/feature/connect-to-wifi/docs/webserver.md **Video demo** https://github.com/user-attachments/assets/283e32dc-2d9f-4ae2-848e-01f41166a731 ## Additional Context - **Security considerations**: The web server has no authentication—anyone on the same WiFi network can access files. This is documented as a limitation, recommending use only on trusted private networks. Password obfuscation in the credential store is XOR-based, not cryptographically secure. - **Memory implications**: The web server and WiFi stack consume significant memory. The implementation properly cleans up (stops server, disconnects WiFi, sets `WIFI_OFF` mode) when exiting the WiFi screen to free resources. - **Async operations**: Network scanning and connection use async patterns with FreeRTOS tasks to prevent blocking the UI. The display task handles rendering on a dedicated thread with mutex protection. - **Browser compatibility**: The web interface uses standard HTML5/CSS3/JavaScript and is tested to work with all modern browsers on desktop and mobile. --------- Co-authored-by: Dave Allie <dave@daveallie.com>
