Renaming ask to query has introduced a bug in:

https://github.com/clade/ThorlabsPM100/blob/master/ThorlabsPM100/usbtmc.py

Now getName and ask_for_value still try to use the old method, but this results in an exception.

The cross-reference links (inside doc to example.rst and ThorlabsPM100.rst) in the doc/index.rst file are broken. I don't know how to fix it.

Bonjour Pierre,
I'm trying to get power values from a PM100.
here is the very simple code to test i'm using:

from future import print_function

from time import sleep
from numpy import array
import visa

from ThorlabsPM100 import ThorlabsPM100
import ctypes

rm = visa.ResourceManager()
inst = rm.open_resource('USB0::0x1313::0x8072::P2004152::INSTR',timeout=1)

power_meter = ThorlabsPM100(inst=inst)
power_meter = ThorlabsPM100(inst = inst)

power_meter.system.beeper.immediate()
power_meter.read()

returns : <ThorlabsPM100.ThorlabsPM100.read object at 0x02190FD0>
Seems like the value is stored at the address : 0x02190FD0 but i can't get to read the value stored at this address.
Seems like i'm not using your script properly.
Do you have any idea ?
Thanks for your help.

Is this library compatible to work with the PM100USB? And I feel like I have seen comments that this is for python 2, not python 3. Is this correct? How might I get this to work with python 3 and a PM100USB?

When I use powermeter.sense.correction.wavelength = 1550 or 800 the obtained optical power from powermeter.read does not change while it does change on the powermeter software from thorlabs. Is this a bug? powermeter.sense.correction.max_wavelength works fine for example.

After #8 was merged, no release was made. It would be helpful to have that code released.

Thanks!

Hi Pierre,

When I read values from the PM100 in Python, it gives the value in units of volts. How do I get it to read in units of watts?

Running example script after installation. Fairly new to pyvisa, so not sure what the issue is here. Also when I search resource manager, no objects are returned but instrument is findable otherwise.

Only works on Linux?
How can I get the connect string? USB0::0x0000::0x0000::xxxxxxxxx::INSTR

Hello,

Is there a way to switch the PM100A/D console to a local mode (i.e., opposite to remote) after measurements are done? In Thorlabs' C++ API, there is a function PM100D_close() that does exactly this, but I could not find how to do the same using this Python package.

I tried releasing the ResourceManager like this:

rm = visa.ResourceManager()
inst = rm.open_resource('USB0::0x1313::0x8079::xxxxxxxx::INSTR')
power_meter = ThorlabsPM100(inst=inst)

#
# Measurements
#

rm.close()

But it does not bring the console to local mode. The only way so far is to turn it off and on again.

I have a PM100A Thorlabs device connected to a raspberry pi via usb. I can see that the device is connected to /dev/usbtmc0. I am getting the below result when trying to do anything with this library. Any idea what I am doing wrong?

When using the module I get the following warning from pyvisa's resources/messagebased.py file:

FutureWarning: ask is deprecated and will be removed in 1.10, use query instead.
  '1.10, use query instead.', FutureWarning)

It would be nice if this module could be adapted accordingly.
