Getting Started

Install via pip from PyPI:

pip install di2008-python

See Available DI-2008s:

from di2008_python import print_all_daq_metadata
print_all_daq_metadata()

Instantiate DI2008 Object with Dictionary of Parameters:

from di2008_python import DI2008, DI2008Channels, DI2008Layout, DI2008TCType

# Enable the DI-2008 with a K-Type thermocopule in Analog Channel 1, an N-Type Thermocouple in Analog Channel 3, and the Digital Channel active
di2008 = DI2008({
        # Global Settings
        DI2008GlobalAnalogLayout: (DI2008Layout.TC, DI2008TCType.K)
        DI2008GlobalScanRateSettings.SRATE: 4,
        DI2008GlobalScanRateSettings.DEC: 1,
        DI2008GlobalScanRateSettings.FILTER: {
            DI2008AllChannels: DI2008FilterModes.AVERAGE,
            },
        # Serial Numbers of DAQs to apply
        DI2008GlobalSerialNums: [<DI-2008 Serial Num>, <DI-2008 Serial Num>, ...],
        # Overwriting settings for a given DI-2008
        <DI-2008 Serial Num>: {
            DI2008Channels.CH1: (DI2008Layout.TC, DI2008TCType.N),
            DI2008GlobalScanRateSettings.FILTER: {
                DI2008Channels.CH1: DI2008FilterModes.LAST_POINT,
                }
            }

This interface uses named enumerations to ensure that what settings are being used is clear and concise

Current Features:

• Thermocouples
• ADC Reading
• Changing Scan Rate, Decimation, and Filtering Mode
• Automatic ChannelStretch Synchronized Initialization
• Enforce cleanup on stopping
• Changing Packet Size
• Interface with the info operator

Planned Features:

• Reading configuration from .json/.toml files as well as raw Python dictionaries
• Digital Channels
• Specify Digital Input as well as Output
• CJCDelta
• Rate Measurement
• LED Color
