In the previous article, we installed the QP framework, the QM tool (a graphical modeling tool), and the QP-nano Arduino library.<\/span><\/p>\n

This article will focus on understanding various transition execution sequences in the nested hierarchical state machine and event propagation.<\/span><\/p>\n

\"Figure
Figure 1. Transition execution sequence and Event propagation<\/span><\/figcaption><\/figure>\n

 <\/p>\n

When events are sent to the nested hierarchical state machine, it refers to how the transitions occur from one state to another and the order of execution of various behavioral actions. To gain insights into this process, we have an example code available at the location indicated in Figure 1. You can easily launch the application in Visual Studio and test it, as demonstrated below.<\/span><\/p>\n

 <\/p>\n

Firstly, there is no need to connect any board to the computer for this. You should navigate to the QP installation folder. Let’s proceed there.<\/span><\/p>\n

Go to the ‘C’ drive, then qp \u2192 qpc \u2192 examples \u2192 workstation<\/strong> \u2192 and open qhsmtst<\/strong>. In this folder, you can launch the Visual Studio solution<\/strong>, as shown in Figure 2. For this, Visual Studio<\/a><\/strong> needs to be installed on your system.<\/span><\/p>\n

\"Figure
Figure 2. Qp installation folder<\/span><\/figcaption><\/figure>\n

 <\/p>\n

The project is open, and let’s go back to that installation folder. And <\/span>qhsmtst.sln<\/b> is a QM model file. This you have to open using the QM tool you installed in the past.<\/span><\/span><\/p>\n

You installed QP frameworks in the past that also installed the QM tool, now let’s launch that.<\/span><\/p>\n

 <\/p>\n

And after that, by using that QM tool, open the <\/span>qhsmtst<\/b> model file. I will just copy the <\/span>qhsmtst<\/b> path and go to QM tool\u2192 File \u2192 Open model\u2192 paste that copied path \u2192 just open <\/span>qhsmtst<\/b>.<\/span><\/span><\/p>\n

And after that, expand the HSMs package, double click on QHsmTst: QHsm. So, that opens the state machine of QHsmTst: QHsm\u2018s class.<\/span><\/p>\n

\"HSM

 <\/p>\n

We’ll understand later how to create all these things by scratch, like creating a class, adding attributes, adding operations, adding state machines, and those things.<\/span><\/p>\n

 <\/p>\n

\"nested
Figure 4. Nested hierarchical state machine<\/span><\/figcaption><\/figure>\n

 <\/p>\n

Figure 4 shows a nested hierarchical state machine of this project. In this diagram, you see, it receives various events. The events are named like A, B, C, D, up to I. There are various events sent to this project to observe various transitions. <\/span><\/p>\n

 <\/p>\n

\"nested
Figure 5. Example<\/span><\/figcaption><\/figure>\n

 <\/p>\n

For example, The code is currently in the state s211, send one event, I will send the event g. When you do that, s21-G; s211-EXIT; s21-EXIT; s2-EXIT; s1-ENTRY; s1-INIT; s11-ENTRY; these are a transition execution sequence for the event g, received when the state machine’s state was s211, as shown in Figure 5.<\/span><\/p>\n

 <\/p>\n

 <\/p>\n

We will understand this one by one. Before that, we will understand how to integrate this project with Arduino. And we will understand how to create the files( shown in Figure 6). We will learn how to use QP frameworks and code generation directives to generate various function declarations and function definitions, etc. But, if you don’t want to try with Arduino, you can try with the computer, as I explained.<\/span><\/p>\n
