CODE CONCERNS

There are some notes concerning the program code that Iýll cover that will hopefully be useful to you.

The first concerns the event handler for the timer in the interface part of the code. I have established a property interval value of 1000, which corresponds to one second. You can establish other intervals of time for measurement, but take into account that the minimal interval of time cannot be less than 55 ms. The hardware timer PC does not allow this interval to be less!

The second note is with developing the interface. Iýve used the interface described here only as a sample. Naturally, you can develop your own interface using other Delphi components. You even design the diagram by means of a component TChart because the GetData function can be used as a separate module.

Additionally, I would like to offer the C++ fans a simple console application written in Visual C++ 6.0 as an alternate for the control program (see Listing 2). The input signal handler is realized as function GetData (lines 25ý47 of Listing 2) and can be used separately while developing the application.
