1 yfios Introduction

Yfios is short for yfsoft I/O server. In the IOT and cloud computing era, everything is data-centric. Different sensors access the network in different ways, provide services to different end users through cloud computing.

In order to adapt to the development of this new situation, it accelerates and reduces the cost of various sensors and smart modules to the Internet. net micro framework system to build a lightweight embedded Configuration System in the IOT Era --Yfios.

For more information, see yfios technical whitepaper.

2. Policy development 2.1 yfios SDK Installation

See the yfios Installation Guide.

2.2 create a policy project

Select the yfios strategy template for policy development.

 

2.3 Code Template

 

Public strategyinfo getstrategyinfo ()

{

Strategyinfo info = new strategyinfo ();

Info. Name = Name;

Info. configsize = 0;

Return Info;

}

The Code Template automatically generates the above Code.

2.4 Hello World

In the onrun function, add the following code:

Public int onrun (ioperate op, strategymode mode, object Arg)

{

Op. Print (messagetype. debug, "onrun", name );

 Op. Print (messagetype. Information, "Hello world !!! ", This. Name );

Return 0;

}

2.5 policy test 2.5.1 compile and add a policy

 

Compile the policy code we just compiled. Start the yfios Manager program, click the policy list item in the tree control, and double-click Create... in the list control ...] The policy form is displayed.

Select the debug \ Le \ yfiosstrategy1.pe file.

 

Go to the Execution Mode panel, select the execution mode as loop, and set the cycle to 200 ms.

2.5.2 configure Project Properties

Click project properties in the tree control and double-click Configuration data in the list control. The following page is displayed. By default, user debugging, general information, and system debugging information are not checked.

 

Select all options.

2.5.4 project deployment and debugging

After saving the project, click debug> deploy (or click the deployment icon) to deploy the project.

 

2.5.5 project operation

Click debug> start to start the project.

 

In the information output window, we can see that the policy has been correctly loaded and the Hello world !!!

3. Policy debugging

Although the compiled policy can be debugged in yfiosmanager by means of information output, this debugging method is not ideal if the policy is complicated.

Therefore, we construct a tinyiosemulator for policy debugging in the Visual Studio 2010 environment.

Because yfsoft. drivertest is a standard. Net micro framework program, you need to set the system to. Net micro framework system mode during debugging.

 

EnsurePf9AndGndConnection.

3.1 Build tinyiosemulator

 

The tinyiosemulator project must reference the policy we just created.

The main code for testing is as follows:

Public class yfiosemulator

{

Yfios IOS = new yfios ();

Public void run ()

{

Yfiosstrategy1 MVS = new yfiosstrategy1 ();

MVS. onload (IOS. Operate, null );

While (true)

{

MVS. onrun (IOS. Operate, new strategymode (), null );

Thread. Sleep (3000 );

}

}

}

3.2 single-step debugging

As you can see, in the Visual Studio development environment, we can debug it, And the debugging window also outputs Hello world !!! Information.

 

4 additional instructions

This article is just an article about getting started with policy development. To write a complicated policy, you also need to learn a variety of development knowledge.

The content related to higher-level policy development is as follows:

(1) set the rule running mode;

(2) Develop policy graphics;

(3) mutual policy calls;

(4) The policy code references the third library;

(5) yfiobc operations;

(6) directly call the driver for a policy;
