Hello and welcome to the Spoken Tutorial on “Interactive Simulation in Xcos Using Slider”. |
Show Slide: Learning Objectives |
In this tutorial, we will learn how to:
|
Show Slide: System Requirements |
To record this tutorial, I am using
The process demonstrated in this tutorial is identical in Linux OS also. |
Show Slide: Pre-requisites |
To follow this tutorial, you should have
|
Show Slide: Interactive Simulation |
|
On the Scilab console, Applications>>Xcos. |
Open the Scilab console. In the menu bar click on Applications and select Xcos. |
Cursor on the Palette browser window and Untitled-Xcos window. |
Notice the Palette browser window is located on the left side. The Untitled - Xcos window is on the right side. |
Cursor on the Palette browser window, Sources>>TKSCALE . |
In the Palette browser-Xcos window, click on Sources palette. In the right panel, scroll down and click on the TKSCALE block. |
Cursor on TKSCALE and Untitled-Xcos window. | Let us drag and drop this block in the Untitled-Xcos window. |
On the Palette browser window, Sinks>>CSCOPE. |
Next, go to the Palette browser-Xcos window. Click on the Sinks palette. In the right panel, scroll down and select the CSCOPE block. Now, drag and drop it after the TKSCALE block. |
On Untitled-Xcos window, Double-click on TKSCALE. |
Next we will see the parameters for the TKSCALE block. Double-click on the TKSCALE block. |
On Scilab Multiple Values Request, |
A window named Scilab Multiple Values Request appears. It displays the TKSCALE block parameters. |
Point to the Min value. |
Here, “Min value” -10 represents the minimum value in the range of the slider scale. |
Point to the Max value. | “Max value” 10 represents the maximum value in the range of the slider scale. |
Point to the Normalization.
Click on OK. |
And “Normalization” 1 represents the interval value of the slider scale.
Click on OK. |
Point to the black input of CSCOPE. | The black input port in the CSCOPE carries the data values. |
Point to the red input of CSCOPE. | The red input port in the CSCOPE represents the events.
The red input can connect only to a block that generates the events. |
Cursor on the Palette browser window, Sources>>CLOCK _c. As per narration. |
To generate the events, go to the Palette browser-Xcos window. Click on the Sources palette. Then click on the CLOCK underscore c block. Drag and drop the CLOCK underscore c block above the CSCOPE block. |
Hover cursor on Untitled-Xcos window. |
We have collected all the required blocks in the Untitled-Xcos window to do the simulation. Let us now connect the blocks together. |
On Untitled-Xcos window, Connect as per narration. |
Select the black output port of the TKSCALE block. Connect it to the black input port of the CSCOPE block. |
On Untitled-Xcos window, Connect as per narration. |
Next select the red output port of the CLOCK underscore c block. Connect it to the red input port of the CSCOPE block. |
On Untitled-Xcos window, Connect as per narration. |
Next select the red input port of the TKSCALE block. Connect it to the line connecting CLOCK underscore c and CSCOPE block. |
On Untitled-Xcos window, Connect as per narration. |
Use the left mouse click to create line bends and then connect it to the line. Now let us simulate this file with the default values. |
On Untitled-Xcos window, Click on start. |
To start the simulation, go to the toolbar of the Untitled-Xcos window. Then click on the Start button that is of the shape of the play button. |
Cursor on the Slider and the Graphic window. |
Two windows get opened. The left window will display the slider. The right Graphic window will display the output of the system. |
Hover cursor over slider |
Notice that the slider opens and closes quickly. It doesn’t give a chance to make use of this slider. This is happening because Xcos is trying to simulate this file at computer time. |
Close Graphic window | To handle this problem, first close the Graphic window. |
On Untitled-Xcos window, Simulation>>Setup |
Then go to the menu bar of the Untitled-Xcos window and click on Simulation. Then click on Setup. |
On Set parameters window, Cursor on Real time scaling |
A pop up window named Set parameters appears. We will change the default value of the real time scaling to 1. |
Hover cursor over Set parameters window. Click on OK. |
Keep the other parameters unchanged. Then click on OK. |
On Untitled-Xcos window, click on Start. |
To start the simulation, go to the toolbar of the Untitled-Xcos window. Click on the Start button. |
Cursor on Graphic window and slider | A Graphic window and the slider will open. |
Hover cursor over the slider. Hover cursor over slider and Graphic window. |
Now I’ll change the value of a parameter using the slider. Notice that I am changing the value while the simulation is running. Observe the changes on the Graphic window as I change the slider value. So this is how we can make the Xcos simulation interactive using a slider. |
This brings us to the end of this tutorial. Let us summarise. | |
