Connecting to SDP-K1 in Python

Category: Software
Product Number: EVAL-SDP-CK1Z


I've been trying to run python example for the AD5754R from this link: pyadi-iio/examples/ at master · analogdevicesinc/pyadi-iio · GitHub and also a modified code

libiio and pyadi-iio has been installed and updated as instructed here: Quick Start - Analog Devices Hardware Python Interfaces 0.0.16 (

Below is the error message I keep getting. From what I could understand, there seems to be an issue connecting to the SDP-K1 COM port. I verified that I am using the correct port via IIO oscilloscope.

Any thoughts on where the issue might be? 

Best regards
