1. Installing Libiio Drivers

a) Windows Environment

For Windows, directly install the libiio driver by using the libiio-0.24.gc4498c2-Windows-setup.exe file.

Download link:
libiio-0.24.gc4498c2-Windows-setup.exe

b) Python Environment Installation

On Windows, it is recommended to use Anaconda (which includes the Spyder IDE). Download link:
Anaconda

c) Setup Procedure

After installation, open the Anaconda Prompt command window and enter iio_info -s. If you see the output as shown below, it indicates that the libiio driver has been installed correctly.

After installing, open Spyder (an IDE included in Anaconda), and in the IPython console, run the following command to install pyadi-iio:

pip install pyadi-iio==0.0.13

Next, create a new .py file, and enter:

import adi
# # Check if pyadi-iio is installed successfully
print("pyadi-iio version:", adi.__version__)

Run the program, and in the bottom-right of the IPython console, you should see the printed information: "pyadi-iio version: 0.0.13". This confirms that pyadi-iio has been successfully installed.

d) Testing H102

Create a new Python file with the following code and execute it to receive data.
