Best pattern to use for multithread in vi ?

[morngoose]

Hi,

I need to create an app, which will communicate to 5x usb to serial converters at the same time.

App needs to detect individually when the USB device is connected, upon connection, send it a few commands, and wait for removal. This repeats when the next unit is connected.
This all needs to happen, 5 x in parralel

I am not sure what would be the besy approach to use?
The obvious would be 5 while loops, but I am sure there must be something better?

Thanks!

5 loops might be an over complication, you might consider a queued state machine architecture.  Are these processes very time intensive?

Thanks for the reply.
They are processor intensive I would say, as it involves downloading commands through a serial port, 5 at the same time

Do you have a example of a queued state machine architecture ?
I am fimiliar with the state machine, but a novice with queues

Thanks

Hi Goose,

There is an example in the Find Examples option under the Help menu in LabVIEW called Queue Basics.vi - this should be useful for you if you want to get started in understanding how to use queues within your code.
