Interactive script with DSS

Other Parts Discussed in Thread: TMS320F28335, TEST2

Hi,

I designed a board using the TMS320F28335 and now I'm trying to write a script to test the board. I'm not a software developer and do not know a lot about javascript. I looked at the example scripts provided with the code composer studio installation and all the scripts provided only produce output to the console, none of them takes input from the console. In my case I would have liked my script to prompt the user to set some inputs on my test fixture (potentiometers, switches...) and then wait for a keystroke before proceeding.

How do you make your script to wait for a keystroke before proceeding? Code snippet is welcome. Pointing me to a relevant documentation is also welcome. Sample console based highly interactive scripts are very welcomed.

Best regards,

Hi Albert,

You can use the java console functions to prompt for input to your script.

ex:

importPackage(Packages.java.lang);

var c = new System.console();
print("Enter value now: ");

var input = c.readLine();
print("Value is: " + input);

Thanks

Hi Ki,

Thanks for your suggestion, but it didn't work. I get the error below:

js: "d:\smc\Test_Sripts\A5\Test2\Test2.js", line 21: Java class "java.lang.System" has no public instance field or method named "Console".
js: "d:\smc\Test_Sripts\A5\Test2\Test2.js", line 21: org.mozilla.javascript.EvaluatorException: Java class "java.lang.System" has no public instance field or method named "Console". (d:\smc\Test_Sripts\A5\Test2\Test2.js#21)

Please note that the package import instruction is as follows:

importPackage(Packages.java.io);

Still looking for a solution...

Best regards,

This is the package you need:

importPackage(Packages.java.lang);

Here is more documentation on using Console:

Thanks

Hi,

I see the same error and I'm doing:

importPackage(Packages.java.lang);

Error -->

js:> var c = new System.console()
Java class "java.lang.System" has no public instance field or method named "console".

I basically would just like to run the CCS script, but have user controlled 'stop-go' ability where I manually make some power changes to the HW I'm using.

Any suggestions would be greatly appreciated.

Kind Regards,

Mark.

drop the 'new' keyword try

var c = System.console();

Hi,

No this returns the same error unfortuantely.

Have you any other suggestions for implementing a user-interactive stop-go ability in DSS?

Mark.

Hi,

I have figured a work around for my problem. I use the Rhino js function runCommand() which goes and executes a windows command.

I place this where I need to pause the script to make manual HW changes.

I use runCommand("calc") which starts up the calculator. It holds till you close the calculator and then continues the script.

A bit daft, but it does the job.

Hi Mark,

This is what I do:

Make sure you import the packages below:

importPackage(Packages.java.lang);
importPackage(Packages.java.io);

Then in your script at the appropriate location call the methodes below:

System.out.println("Press Enter when ready...");
stdin.readLine();

Hope this helps and not too late.

Hi Albert,

does the above approach work for you?? It throws an error for me.

Yes Sugham, that's the approach that worked for me. Now I don't know the java intricacies enough to figure out why that would throw an error for you.

If you read the DSS documentation you'll see that there is a way of running the Rhino debugger by modifying some of the .bat files, that might help you figure out what is going wrong.

Best regards,

Albert.
