PyRealtime

PyRealtime is a package that simplifies building realtime pipeline systems Python. It is designed to be simple enough to start visualizing data in just a few lines and scalable enough to support more complex workflows. It supports realtime plotting (Matplotlib), serial communication (Pyserial), and socket connections out of the box. It uses a declarative data flow syntax, which means you specify how the pipeline should behave and then you run the pipeline.

For example, you can build a real time plot of data coming from a serial port in just three lines.

import pyrealtime as prt

serial_layer = prt.SerialReadLayer(device_name='COM2', baud_rate=9600)
prt.TimePlotLayer(serial_layer, window_size=100, ylim=(0, 100))
prt.LayerManager.session().run()

Features:

• Serial port read/write
• Realtime plotting using Matplotlib
• UDP Socket read/write
• Audio input from microphone
• Realtime 3D visualizations using PyGame
• Data logging to a file
• Realtime playback of recorded sessions

Installation

Dependencies

PyRealtime explicitly requires numpy and Matplotlib. For other optional features, other packages are required.

• pyserial for serial communication
• pygame for 3D visualizaton
• pyaudio and scipy for audio input
