-[[/resources/tools-software/linux-software/pyadi-iio|PyADI-IIO]] is a python abstraction module for ADI hardware with IIO drivers to make them easier to use. This module provides device-specific APIs built on top of the current libIIO python bindings. These interfaces try to match the driver naming as much as possible without the need to understand the complexities of libIIO and IIO.\\ 
  
-===Installing and Setting up the PyADI-IIO Enviroment=== +===Code Snippet from the CCES Project=== 
-  - There are minimal variations in installing PyADI-IIO depending on your operating system.   \\ > [[/resources/tools-software/linux-software/pyadi-iio| You may refer to this guide regarding the initial steps to install PyADI-IIO for your machine.]] \\  +In case you want to generate your own hex file to be used, there are two attributes from the AD7798/AD7799 family that you should note --- the polarity and the gain.  
-  - Upon performing the OS-specific steps, we will also be needing the matplotlib package for the plotting of data: <code> pip install matplotlib</code> +\\ {{ :resources:eval:user-guides:circuits-from-the-lab:cn0548:cces.png?600 | CCES code snippet}} \\ 
-<note> In case your system is specifically designed for a certain application, you may want to consider using a virtual environment in doing this demo. It should also help in dealing with system config and version issues.</note>+It is important to set the polarity of the ADC according to your configuration and application. When the polarity is set to unipolar, effectively restricting the user to follow the polarity of the terminals, the maximum bit resolution of the ADC is used in its conversion compared as to when the polarity is set to bipolar where the bit resolution is equal to (n-1) bits where n is the maximum bit resolution of the ADC. 
 +\\ \\ 
 +The other important attribute is the gain. The gain attribute corresponds to the internal gain of the ADC. A user can apply an internal gain to the ADC allowing the differential ADC input to be amplified. This feature can come in handy when dealing with small signals but the user must take precaution as applying an internal gain effectively decreases the input rating of the board. It is highly recommended to read and consult the datasheet of the ADC before creating a customized hex file.
