LabVIEW
how to make a command automatically sending
I've been following this thread and I must say that you have not studied any Labview tutorials at all. You also have not followed anyone's advice. I've decided to help you anyway. Just one time only unless you make an effort to learn Labview on your own.
Study the following picture. The serial port is initialized ONE TIME ONLY, at the beginning. There is an event structure to capture the boolean buttons value change. Inside the event, you place your stripped down subvi. The subvi only contains code to create the strings you want to write to the serial port. There is no serial port functions in the subvi. You need to create a subvi for each one of your boolean buttons. The output of the subvi is a string array with 3 elements. Feeding this into the for loop will cause the loop to run 3 times, one for each element. The code inside the loop will write, delay, then read. No need to repeat the code 3 times, the loop will do that. The loop is inside a False case so that it only executes if stop is not pressed. There is an event case for the stop button. When pressed, the loop will stop.
Now you need to create the other subvi's for your string array and create an event case for each boolean button. Put the appropriate subvi inside each event. I've created one subvi for you as a start. It is attached. You can do the others.
