What is DaqOpen?

DaqOpen is a Python library designed for developers working with data acquisition (DAQ) systems. It allows you to collect, process, and stream real-time data from Arduino Due (and maybe other controllers in future)

Why Use DaqOpen?

  • Easy Integration into your own application
  • Real-time Data Acquisition and processing
  • Simulated Data Acquisition for testing without hardware
  • Flexible Data Buffering with support for delays and offsets
  • ZeroMQ Streaming to transfer data over networks
  • System Synchronization to ensure time accuracy

Getting Started

Install the library via pip:

pip install daqopen-lib

Example of basic usage:

from daqopen.duedaq import DueDaq

# Initialize DAQ in simulation mode
my_daq = DueDaq(serial_port_name="SIM")
my_daq.start_acquisition()
data = my_daq.read_data()
print(data)
my_daq.stop_acquisition()

Core Features

  • ADC driver: Driver for communicating with Arduino Due (included firmware) and packing the data to numpy arrays.
  • Circular Channel Buffer: A class representing a circular buffer for holding needed amount of data for viewing, calculating and storing.
  • DAQ-Info Class: Can be used to exchange informations regarding the interpretation of the data packages. It holds adjustment values and info about the acquisition rate.
  • ZMQ-Support: Transfer the acquired data in realtime via zmq to other applications or hosts
