Python wrapper for IOTech/Measurement-Computing data-acquisition devices.
Keywords: DaqBoard, DaqBook, DaqLab, DaqScan, Personal Daq, TempBook, WaveBook.
Read a single ADC sample from a single input channel:
from __future__ import print_function, division
from PyIOTech import daq, daqh
device_name = b'DaqBoard3K0'
channel = 0
gain = daqh.DgainX1
flags = daqh.DafAnalog | daqh.DafUnsigned | daqh.DafBipolar | daqh.DafDifferential
max_voltage = 10.0
bit_depth = 16
try:
dev = daq.daqDevice(device_name)
data = dev.AdcRd(channel, gain, flags)
# Convert sample from unsigned integer value to bipolar voltage.
data = data*max_voltage*2/(2**bit_depth) - max_voltage
print(data)
finally:
dev.Close()For more complex, commented examples, see the examples directory.
There is no official documentation for PyIOTech, however the python function-signature follows closely the C/C++ or Visual Basic function-signature, as documented in the IOTech Programmer's Manual. For the specific python API, consult the source code or the examples.
This is a pure python distribution with no external dependencies (except the IOTech device driver "daqx.dll"). Tested with python 2.7 and 3.4.
To install, run: $ python setup.py install
Heavily based on pydaqboard.

I'm currently no longer employed at a lab using IOTech devices, so I'm no longer in a position to maintain this library. If you're interested in being a maintainer for this package, just ask and I'll happily give you write permissions.
