One solution would be to simply handle the exception and stop populating the variables (after giving them some sentinel value up front). This could be done with something like:

How to catch all kinds of interrupt Requests in jSerialCom library?

QUESTION

How to get data output to the application via the com terminal?

Asked 2020-Nov-11 at 17:10

Good afternoon, I'm using a sketch for a test that uses an RS-232 connection. I need to understand how and what commands to type in the com-terminal in order to get and see the data in the application window of this sketch near the list of text variables, I have attached a screenshot. I am completely new to this business, tell me the solutions.

This is needed for debugging, sometimes for configuration. I attached a sketch and code, you can check it. The sketch works correctly if the application is installed com0com.exe on the computer and the com port is open via the terminal. The meaning of the code is to send a sequence of bytes to the COM port and display data (numbers) on the screen for variables in applications.

I wonder if there is something wrong with copying std::function as I do in the constructor of the s2lp_custom_ikm class?

No.

The std::function copies in your constructor (both the initialiser and the body) are safe.

The program snippet shown does not contain a bug capable of the symptoms you report.
