AD9467 FMC Start Capturing data and see the output waveform in ADI IIO Oscilloscope

Category: Software
Product Number: AD9467_Eval_board
Software Version: no-OS (master branch)

Hi  

Thank you for your recommendation. At this point, we are happy with the project's success because it has been made possible by your excellent suggestions that have helped us advance to new levels on a daily basis. The way you help in this thread was precious  RE: Generates error in No-OS (2019_R2) using SDK 2019.1 

You suggested the iio-oscilloscope, which is described here: wiki.analog.com/.../tinyiiod demo
With the help of this link's instructions, we were able to create a project utilizing the TINYIIOD=y flag and attach it to a iio-oscilloscope. Here is the snapshot
 

Here, the connection was successfully established, and then the ADI IIO Oscilloscope window appeared.

Now, we'll go over three scenarios with you in which we use an input signal from Analog Discovery 2 and an ADI IIO Oscilloscope to view the ad9467's output voltage signal.

Scenario:1 You can examine the same sinusoidal signal on the oscilloscope during run time by providing sinusoidal input from Analog discovery 2. The image is shown below. Waveform signal (Running), IIO Oscilloscope (Running)
 

Scenario:2 You can examine the same sinusoidal signal on the oscilloscope during run time by providing triangle wave input from Analog discovery 2. Here's a picture, Waveform signal (Running), IIO Oscilloscope (Running)

In scenario 2, is it required to launch or debug the project in order to see the various waveforms in the oscilloscope? By the way, even after a relaunch and another round of code-debugging, the sinusoidal wave remains. Can you provide me some ideas on how we can view various waveform signals in the oscilloscope while it is in run-time?

Scenario:3 When we stop the Analog Discovery 2 input signal during operation, there is no signal at first and a sinusoidal wave arises at the ending. This is the picture. Waveform signal (STOP), IIO Oscilloscope (Running)

Here are the issues:

What are the methods, concerns, and things to keep in mind to obtain the same run time environment if the ADI IIO Oscilloscope plots the data continuously in run time as you instructed? Does the IIO Oscilloscope adjust appropriately if we change the input signal from Analog Discovery 2 or not? If so, what should we do?
