forward = Right down = Left
Added new blocks (Move and Color) Only Forward command is working with vex WORK IN PROGRESS
Previous block functionality still working on new block functions
Found problem: the number for the muscle energy window and the raw data doesn't match up
- need to connect the vex through AP before starting the application
This reverts commit ceb24df.
- fixed colors
…into feature/ganglion
- no longer degrees for turn block (for kids) - Shortcut is ready to be used (Neuroscope-EMG) -Updated gitignore (pycache)
* src/main/index.js: - Fixed production build path from loadURL to loadFile with correct relative path - Added Python process spawning with virtual environment detection - Implemented WebSocket connection validation with 10s timeout - Added proper process cleanup on app quit and window close - Updated hardcoded references from Muse to Ganglion devices - Fixed port configuration from 3000 to 3002 * src/renderer/js/muse-client.js: - Fixed duplicate filters property that was overriding device name filters - Added Ganglion service (0xfe84) to optionalServices for proper discovery * package.json: - Updated electron-builder config to include build/renderer directory - Added extraResources for Python executable bundling - Enhanced build scripts with python:build for PyInstaller integration - Updated serve script to use port 3002 - Added build:local script for complete build process * VEXServer.spec (new): - PyInstaller specification for Python server executable - Proper dependency handling for websockets and asyncio - Console executable configuration for debugging * resources/python/VEXServer_dev.py (new): - Created simulation mode WebSocket server for development - Mock VEX robot with full command protocol (led_on, move, turn_left, turn_right) - Enables testing without physical VEX robot hardware - Runs on ws://127.0.0.1:8777 with JSON command interface * requirements.txt: - Added PyInstaller>=5.0 for standalone executable creation **Key Improvements:** - Enables successful Windows executable creation with integrated Python server - Two-process architecture provides reliable communication in both dev and production - Fixed Bluetooth device scanning to properly detect Ganglion devices instead of Muse - Automatic virtual environment detection in development mode - Production builds now bundle Python server as standalone executable - Enhanced development workflow with simulation server for hardware-free testing
…rking WebSocket management **New Features:** * Console UI: Replace frequency bands display with clean console output * VEX Reconnect: Add functional reconnect button to restart VEX connection without app restart * Enhanced Testing: Complete VEX simulation server with comprehensive test suite * Robust WebSocket Management: Proper connection handling with reconnection support **Console System (NEW):** * src/renderer/js/console.js: Clean terminal-like console without timestamps/emojis * src/renderer/index.html: Replace bands display with console container * src/renderer/js/main.js: Integrate Console class replacing BandPowerVis * src/renderer/js/wrapper-functions.js: Connect blockly_print to console output **VEX Reconnect System (FULLY FUNCTIONAL):** * src/main/index.js: Complete WebSocket connection management with proper scoping - Added stopPythonServer() and reconnectVEX() process management - Moved WebSocket variables and functions to global scope for proper access - Implemented createWebSocketConnection() with timeout and error handling - Fixed function scoping issues that prevented reconnection * src/main/preload.js: Expose vexReconnect IPC method to renderer * src/renderer/index.html: Add VEX reconnect button in sidebar (orange refresh icon) * src/renderer/js/events.js: Implement reconnect button handler with visual feedback **Enhanced VEX Testing:** * resources/python/VEXServer_dev.py: Complete simulation server with full command support * test_vex_server.py: Comprehensive WebSocket test suite for validation **Key Technical Improvements:** - Fixed variable scoping: ws and createWebSocketConnection now accessible globally - Proper WebSocket lifecycle management: Close old connections before creating new ones - Enhanced error handling with timeout protection and graceful fallbacks - Clean console replaces cluttered frequency bands display - Robust reconnection process with proper server restart sequence - Enhanced print blocks accept any data type and output to console **WebSocket Reconnection Flow:** 1. Close existing WebSocket connection 2. Stop Python VEX server gracefully (SIGTERM with SIGKILL fallback) 3. Wait 2 seconds for cleanup 4. Restart Python VEX server 5. Wait 3 seconds for server initialization 6. Re-establish WebSocket connection with timeout protection 7. Resume VEX command functionality
**Block-to-Text Converter:** * src/renderer/js/simple-text-view.js: Text coding environment using Blockly's built-in code generation * src/renderer/index.html: Add toggle buttons for block/text modes and export functionality * src/renderer/js/main.js: Integrate text view with existing Blockly system
… app rename Python (resources/python): Add resilient AIM connection loop; server stays alive and retries when robot is offline Add reconnect_robot action to reset robot connection without restarting server Add disconnect_robot cleanup to close websocket threads and sockets before re-init Add status action reporting robot_connected for UI Improve connection logs (attempting / connected / retry) Electron main (src/main): Detect and spawn bundled VEXServer.exe in production Replace waitOn websocket probe with lightweight TCP port polling Guard reconnectVEX against overlap and clear force-kill timer to avoid killing new process Periodically poll server status and relay to renderer via vex-status Fix false-positive connected state by distinguishing wsConnected vs robotConnected Add lazy-init UDP sockets for Tello (no bind to 9000/8890 until needed) Renderer: Add connectivity status dot showing wsConnected (grey/yellow) and robotConnected (green) Add onVexStatus and requestVexStatus to preload for UI updates Packaging/build: Ensure PyInstaller bundle includes vex module/resources and fix spec path resolution Use process.resourcesPath/python/VEXServer.exe in production and improve spawn/path logging Naming/branding: Rename app to "NeuroBlock EMG for VEX" (productName/appId, window title, HTML title) Docs: Update README with "Adding a New Blockly Block (Example: VEX Kicker)" section and build notes Notes: Reconnect button sends reconnect_robot when local websocket is up; only restarts Python process if websocket is down Status dot: grey = websocket down, yellow = websocket up/robot down, green = robot connected Avoid binding to port 9000 unless Tello is actively used
This reverts commit b031569.
…X integration ### Application Branding & Identity - Rename app from 'NeuroBlock EMG for VEX' → 'NeuroBlock EEG for VEX' - Update package.json productName, window title, and HTML title - Update appId to reflect EEG focus: com.htil.neuroblock-emg-vex ### EEG Signal Processing (Muse Headset) - Restore Signal class for real-time EEG data buffering (512-sample buffer) - Restore BandPowerVis for frequency band visualization (delta, theta, alpha, beta, gamma) - Restore FeatureExtractor for band power computation from raw EEG samples - Restore BLE (Bluetooth Low Energy) integration for Muse headset connection - Wire Muse eegReadings callback → Signal.add_data() for live data streaming ### UI Layout - Two-Panel Design - Left panel (45% width): * Top card (40vh): 4 EEG channel graphs (channels 0-3 from Muse) * Bottom card (40vh): Band power frequency spectrum visualization - Right panel (55% width): * Blockly visual programming editor for robot control * VEX AIM robot command center and status display * Console output and device connection status
