Hello,
I have a problem with VISA that has been blocking me for a long time in my project. I have looked everywhere but I can't figure out the origin, I developed an application to communicate with instruments, everything was going well but when I launch the application I select the com associated with the device with the correct parameters on both sides, VISA returns an error. What surprises me the most is that sometimes it works and the communication is established correctly, and sometimes returns me this famous error. I checked everything the cable is good, the parameters are right too.
just for indication I made a pause of 500 ms of reading of VISA read, so that it is synchronized with the return of the instruments.
the protocol used is RS232, I use SCPI commands on VISA Write
the program has worked many times I have tested it but sometimes it blocks the communication
I'm fed up with this library, I see that it's much more complicated to manage these errors.
