-# LED Bar Configuration Tool
-
-A tkinter GUI tool for configuring LED bar settings via mpremote.
-
-## Features
-
-- Download `settings.json` from MicroPython device using mpremote
-- Edit LED configuration settings
-- Upload modified `settings.json` back to device
-- Load/save settings from/to local files
-
-## Requirements
-
-- Python 3.x with tkinter (usually included)
-- mpremote: `pip install mpremote`
-
-## Usage
-
-```bash
-python3 tool/led_config.py
-```
-
-Or make it executable:
-```bash
-chmod +x tool/led_config.py
-./tool/led_config.py
-```
-
-## Configuration Fields
-
-- **LED Pin**: GPIO pin number for LED strip
-- **Number of LEDs**: Total number of LEDs in the strip
-- **Color Order**: RGB or RBG color order
-- **Device Name**: Name identifier for the device
-- **Pattern**: Current LED pattern
-- **Color 1/Color 2**: Primary colors (hex format, e.g., #ff0000)
-- **Delay**: Pattern delay in milliseconds
-- **Brightness**: LED brightness level
-- **N1-N6**: Pattern-specific parameters
-- **AP Password**: WiFi access point password
-- **ID**: Device ID
-
-## Device Connection
-
-Default device is `/dev/ttyUSB0`. Change it in the "Device" field if your device is on a different port (e.g., `/dev/ttyACM0`, `COM3` on Windows).
-
-## Workflow
-
-1. Enter your device path (e.g., `/dev/ttyUSB0`)
-2. Click "Download Settings" to fetch current settings from device
-3. Edit any settings as needed
-4. Click "Upload Settings" to save changes back to device
-
-You can also:
-- Load settings from a local JSON file
-- Save current settings to a local JSON file
