Aind.Ni.DigitalOutput.Configuration 1.10.0

aind-ni-digitaloutput-configuration

A Bonsai extension for configurable NI-DAQmx Digital Output, using runtime channel configuration.

Overview

This package provides Bonsai combinators and sinks for NI-DAQmx digital output, allowing channel configuration to be provided externally at runtime. It is a drop-in replacement for the standard Bonsai.DAQmx DigitalOutput node, but with more flexible configuration.

Features

• Runtime Channel Configuration: Configure digital output channels at runtime
• Type-Safe Configuration: Uses strongly-typed configuration objects
• Multiple Data Types: Supports boolean, array, and matrix inputs
• Bonsai 2.7+ Compatible

Installation

1. Open Bonsai
2. Go to "Tools" > "Manage Packages"
3. Add the NuGet source for this package
4. Search for Aind.Ni.DigitalOutput.Configuration and install

Prerequisites

• Windows
• NI-DAQmx Runtime (required for real hardware use)
• Bonsai.DAQmx (must be installed in Bonsai for this package to work)
• Bonsai 2.7.0+

Note: This package does not include the National Instruments DAQmx drivers or Bonsai.DAQmx. You must install them separately. For CI builds, DAQmx functionality is stubbed and not available.

Components

DigitalOutputConfigurationSource

Generates configuration objects for digital output channels.

• ChannelName: Name for the virtual channel
• Lines: Physical lines to use (e.g., "Dev1/port0/line0:7")
• Grouping: How to group digital lines (OneChannelForEachLine/OneChannelForAllLines)

DigitalOutputWriter

Writes digital values to NI-DAQmx digital output lines using the specified configuration.

• Channels: Collection of DigitalOutputConfig
• SignalSource, SampleRate, ActiveEdge, SampleMode, BufferSize: Standard DAQmx timing properties

ToDigitalOutputConfigCollection

Wraps a single DigitalOutputConfig into a collection for use with DigitalOutputWriter.

Usage Example

DigitalOutputConfigurationSource -> ToDigitalOutputConfigCollection -> DigitalOutputWriter
BooleanSource                  /

Supported Data Types

• IObservable<bool>
• IObservable<bool[]>
• IObservable<bool[,]>
• IObservable<byte[,]> git add . git commit -m "refactor: replace all digital output configuration code with Daq_config.cs, update docs, bump version to 1.6.0, and clarify node usage" git push

Node Descriptions

• DigitalOutputConfigurationSource: Use this node to define the digital output channel parameters (name, lines, grouping) in your workflow. Outputs a configuration object.
• ToDigitalOutputConfigCollection: Use this node to convert a single configuration into a collection, which is required by the writer node.
• DigitalOutputWriter: Use this node to send digital data (bool, bool[], bool[,], or byte[,]) to the hardware, using the configuration(s) provided.
