Actually my question is more related to dll.
xxx_app)AAA_app)Both of which can tx/rx data from zanthric USB-2-CAN device using dll directly.
Now is it possible for both AAA_app & xxx_app to directly use same dll for zanthric device & operate simultaneously?
Is it possible for both GUI to load same DLL for communication?
Will it cause some problems will tx & rx of data in two GUI?
Please suggest.
That’s an important question. I believe it depends on the DLL and the USB driver you activate. I know that a USB DLL/driver that I used made problems when accessed simultaneously even from the same application by 2 threads. I had to synchronize the access using semaphores.
The TCP/IP stack, on the other hand, is intended to work simultaneously with multiple processes. It’s a matter of both hardware and the software above it.
Unlike TCP/IP, there is no standatd “USB stack”. So it depends on the driver running the USB you use.
