• Set the gain (low, high)
• Configure the filters:
  • Fast-roll-off-low-latency
  • Fast-roll-off-phase-compensated
  • Slow-roll-off-low-latency
  • Slow-roll-off-phase-compensated
  • Non-oversampling
• Adjust the volume
• Fully configurable through JSON configuration file

Requirements

• Python 3.7 or higher
• usb module
• PyGObject

Installation

From AUR (Arch Linux)

The package is available on the Arch User Repository (AUR). You can install it using your preferred AUR helper:

# Using yay
yay -S dawnpro-gui

# Using paru
paru -S dawnpro-gui

Or build it manually:

git clone https://aur.archlinux.org/dawnpro-gui.git
cd dawnpro-gui
makepkg -si

Manual Installation

To install pyusb, run:

pip install pyusb

To install PyGObject, it may depend on your distro or operating system:

https://pygobject.gnome.org/

Setup

Add the following rule to your udev rules (you may need to adjust the rule name based on existing rules in /etc/udev/rules.d/):

echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="2fc6", MODE="0666"' | sudo tee /etc/udev/rules.d/99-dawn-pro.rules

Then run:

sudo udevadm control --reload-rules
sudo udevadm trigger

Configuration

The application uses a configuration file located at ~/.config/dawnpro/config.json. If this file doesn't exist, the application will use default settings.

Setting Up Configuration

1. Create the configuration directory:

mkdir -p ~/.config/dawnpro

2. Copy the default configuration:

cp config.json ~/.config/dawnpro/config.json

Configuration Sections

The configuration file is divided into several sections:

1. device_constants: USB communication constants

   "device_constants": {
       "BM_REQUEST_TYPE_OUT": 67,
       "BM_REQUEST_TYPE_IN": 195,
       "B_REQUEST": 160,
       "B_REQUEST_GET": 161,
       "W_VALUE": 0,
       "W_INDEX": 2464,
       "VOLUME_REFRESH_DATA": [192, 165, 162],
       "DATA_LENGTH": 7,
       "LED_STATUS_ENABLED": 0,
       "LED_STATUS_TEMP_OFF": 1,
       "LED_STATUS_OFF": 2
   }
   

2. device_identifiers: Device vendor and product IDs

   "device_identifiers": {
       "MOONDROP_VID": 12230,
       "DAWN_PRO_PID": 61546,
       "VOLUME_MAX": 0,
       "VOLUME_MIN": 112
   }
   

3. default_settings: Default values for device settings

   "default_settings": {
       "DEFAULT_VOLUME": 50,
       "DEFAULT_LED_STATUS": "On",
       "DEFAULT_GAIN": "Low",
       "DEFAULT_FILTER": "Fast Roll-Off Low Latency"
   }
   

4. ui_metrics: Window size and UI element spacing

   "ui_metrics": {
       "WINDOW_WIDTH": 400,
       "WINDOW_HEIGHT": 300,
       "MARGIN_TOP": 10,
       "MARGIN_BOTTOM": 20,
       "MARGIN_START": 10,
       "MARGIN_END": 10,
       "SPACING": 10
   }
   

5. logging: Logging configuration

   "logging": {
       "LOG_LEVEL": "INFO",
       "LOG_FORMAT": "%(asctime)s - %(levelname)s - %(message)s",
       "LOG_FILE": "~/.config/dawnpro/dawnpro.log"
   }
   

Example Custom Configuration

Here's an example of a custom configuration that changes some default values:

{
    "default_settings": {
        "DEFAULT_VOLUME": 75,
        "DEFAULT_LED_STATUS": "Off",
        "DEFAULT_GAIN": "High",
        "DEFAULT_FILTER": "Fast Roll-Off Phase Compensated"
    },
    "ui_metrics": {
        "WINDOW_WIDTH": 500,
        "WINDOW_HEIGHT": 400,
        "SPACING": 15
    },
    "logging": {
        "LOG_LEVEL": "DEBUG",
        "LOG_FILE": "~/.config/dawnpro/debug.log"
    }
}

Usage

Ensure the DAC/AMP is plugged in before running the script.

To run the tool, execute the following command:

python main.py
