How can running two device?(analog discovery2) use SDK Manual.

[Sangkyu Choi]

I have two device that analog discovery2,

I wanner run two device at the same time.

I use WaveForms SDK Reference Manual and python.

But Only one of device works.

I think this is the code to change.

print("Opening first device")
dwf.FDwfDeviceOpen(c_int(-1), byref(hdwf))

How do I write the code?

Hi @Sangkyu Choi,

This thread should contain the details that you are looking for:

You should also look at the Device_Synchronization.py example that is within WaveForms SDK.

Thanks,

Hi @Sangkyu Choi

See Device_Enumeration.py Device_Synchronization.py AnalogOutIn_Synchronization.py Device_Info.py Device_InfoEx.py

The easy way, without verifying the connected devices:
dwf.FDwfEnum(c_int(0), 0)
dwf.FDwfDeviceOpen(c_int(0), byref(hdwf1))
dwf.FDwfDeviceOpen(c_int(1), byref(hdwf2))
