WPC Device Driver Python API

About

WPC Python driver contains APIs for interacting with the WPC USB-DAQ, Ethernet and Wifi-DAQ series products.

In order to optimize driver API performance, we adopt async/await structure for the driver implementation as known as non-blocking mode.

Quick Start

In the bellowing example, we use pywpc to find all available WPC devices.

pywpc.pyd is a Python based dll file which support on win10 x64.

>>> from wpcsys import pywpc

>>> dev = pywpc.Broadcaster()
...
Opened handle (Device finder)
 
>>> pywpc.PKG_FULL_NAME
...
WPC Python driver

>>> pywpc.__version__
...
0.2.4

>>> dev.connect()
...
Binded Device finder

>>> await dev.Bcst_getDeviceInfo()
...
[['192.168.5.79', '255.255.255.0', '34:86:5d:19:06:6c', 'Wifi-DAQ-E3-A_R0.3.4']]

>>> dev.disconnect()
...
Disconnected Device finder

>>> dev.close()
...
Closed handle (Device finder)
