A robust Data Acquisition System built with Synnax for managing NI USB-6343 devices and handling various types of data inputs and outputs.

• Automated device discovery and configuration
• Support for analog and digital I/O
• Real-time data processing
• Configurable sampling rates
• Automatic task management
• Excel-based configuration system
• Comprehensive error handling
• Extensive logging

• Python 3.8+
• uv
• National Instruments DAQmx drivers
• Synnax server running and accessible

1. Clone the repository:

git clone https://github.com/Purdue-Space-Program/PSPL_DAQ.git
cd PSPL_DAQ/daq-system
uv sync

2. Run the program:

uv run main.py

# Configure the system
config = DAQConfig(
    sample_rate=1000,  # Hz
    stream_rate=100,   # Hz
    host="your.synnax.server",
    port=9090,
    username="user",
    password="pass"
)

# Initialize the system
daq = DAQSystem(config)

# Configure device paths
device_paths = {
    "Dev5": DeviceWiringPaths(
        data_wiring=Path("inputs/CMS_Data_Test_Dev5.xlsx"),
        control_wiring=Path("inputs/CMS_Control_Test_Dev5.xlsx")
    )
}

# Process devices
for device_name, paths in device_paths.items():
    # Get device
    device = daq.client.hardware.devices.retrieve(
        model="USB-6343", 
        location=device_name
    )
    
    # Create and configure tasks
    tasks = daq.create_device_tasks(device)
    
    # Process data
    daq.process_device_data(
        device,
        pd.ExcelFile(paths.data_wiring),
        pd.ExcelFile(paths.control_wiring),
        tasks
    )

The system uses Excel files for configuration:

• Sheet "AI_slope-offset": Analog input configuration
• Sheet "DI": Digital input configuration

• Sheet "DO": Digital output configuration

The system provides custom exceptions for different error types:

• DAQError: Base exception
• ConnectionError: Connection issues
• ConfigurationError: Configuration problems
• DeviceError: Device-related errors
• TaskError: Task creation/configuration errors
