This package was firstly designed to use experimental device for data acquisition and signal generator, when performing different experiment, such as a step-response test.
Despite this, one can use PYDAQ to acquire and send a signal from any system, using different boards (check jupyter notebook examples folder), through a Graphical User Interface or via command line. In this sense the user is capable to generate a customized signal which can be easily applied to a system.
It is noteworthy that this application makes data acquisition and empirical experiments simpler, faster and easier. This is relevant when the user needs empirical data to construct black box linear and nonlinear models, commomly used in research projects in forecasting and model-based control schemes.
The code provided here allows user to save acquired data in .dat files in a path specified by the user (or at Desktop, if no path is provided), as well as send a user-defined data, which can be any nonlinear input signal (you are strongly advised to check the )

The fastest way to install PYDAQ is using pip:
pip install pydaqNOTE: In this version of pydaq (0.0.3), (NI-DAQmx drivers) must be installed, even if the user is only using Arduino Boards. This issue will be addressed in future versions, allowing Arduino users to use PYDAQ without having to install NI-DAQmx drivers.
PYDAQ requires:
- Installed driver of the board used (Arduino or National Instruments NIDAQ)
- nidaqmx (>=0.6.5) for data acquisition from National Instruments Boards
- matplotlib (>=3.5.3) as a visualization tool
- numpy (>=1.22.3) to process data
- PySide6 (>=6.7.1), PySide6_Addons, PySide6_Essentials and shiboken6 as a Graphical User Interface framework
- pyserial (>=3.5) to manage data to/from Arduino
| Feature | Description |
|---|---|
| Send Data (NIDAQ) | This feature allows the user to send data through any NIDAQ board using a graphical user interface |
| Send Data (Arduino) | This feature allows the user to send data through any Arduino board through a graphical user interface |
| Get Data (NIDAQ) | Here the user is able to get data from a NIDAQ board, using any terminal configuration (Diff, RSE, NRSE), sample time and other parameters. Acquired data can also be saved and plot for further applications |
| Get Data (Arduino) | Here the user is able to get data from an Arduino board, using several options. Acquired data can also be saved and plot for further applications |
| Step Response (NIDAQ) | In this feature one can perform an automatic step response experiment using a NIDAQ board. Data genereted by the experiment can also be saved to be used in further applications, such as obtaining linear and nonlinear models from acquired data |
| Step Response (Arduino) | In this feature one can perform an automatic step response experiment using an Arduino. Data genereted by the experiment can also be saved to be used in further applications, such as obtaining linear and nonlinear models from acquired data |
Using GUI (more details in documentation and jupyter notebook examples):
In the latest version, all functionalities for all boards are incorporated in one single window.
from pydaq.pydaq_global import PydaqGui
