What OS are you running?
I wonder if this project is still maintained, I am having the same problem. And i'm using ubuntu 18.04 LTS.
Another thing is in pmapi.py
file at line 23,
devices = usb.core.find(find_all=True, idVendor = 0x2AB9, idProduct = 0x0001)
the device id is very specific. Do I need to change the device id for my device cause it doesn't match this vendor and product ID.
Perhaps a little bit late, but better late than never ;).
I encountered this problem as well and what fixed it for me was running your script with sudo e.g.,
sudo python3 my_script.py
If you are running PyMonsoon in a virtual environment please make sure you provide the path to the python3 binary in the virtual environment as sudo python3
will use your global python3 installation by default.
So first get the path of the python3 executable in your virtual environment:
which python3
Then use that path when running your script:
sudo <my_python3_path> my_script.py
or as a one-liner: sudo $(which python3) my_script.py
.
If this does not work:
Hi guys. I am having the same issue. I use LVPM and follow the example code in the official API document:
import Monsoon.LVPM as LVPM
import Monsoon.sampleEngine as sampleEngine
import Monsoon.Operations as op
Mon = LVPM.Monsoon()
Mon.setup_usb(serialno=13379) # my monsoon's serial number
Mon.setVout(4.0)
engine = sampleEngine.SampleEngine(Mon)
engine.enableCSVOutput("Main Example.csv")
engine.ConsoleOutput(True)
numSamples=5000 #sample for one second
engine.startSampling(numSamples)
I have tried it on Ubuntu 18.04 and Windows 10 with Python 3.6, and both cases show errors like:
File "[testMonsoon.py](http://testmonsoon.py/)", line 8, in <module>
Mon.setVout(4.0)

self.Protocol.sendCommand(op.OpCodes.setMainVoltage,vout)

result = self.DEVICE.ctrl_transfer(op.Control_Codes.USB_IN_PACKET,op.Control_Codes.USB_SET_VALUE,0,wIndex,4,5000)

- Is the Monsoon actually turned on ;)?
- Did you set the serial for your Monsoon?
I have tried to sudo
but it does not help. Monsoon is on during the test.
Any suggestion for this issue? Thanks.

Hi @roy-uiowa. I got the same concern. I tried changing the vid and pid in pmapi.py
but still not working. Have u solved this problem? Thanks!

Hi @dfguooo, I recommend you should install ubs filter on your Window machine and try it again. I installed a quite old version: libusb-win32-devel-filter-1.2.6.0.exe and it works fine.
Download and use libUSB but do not open the powertool tool. This is my solution [windows]
I suspect this is because USB is not detected by monsooon. But monsoon installation includes libusb1, and I have also installed libusb manually.
So how to address this issue?
