avioding race condition in 2 loops

[sebastiant]

Hi

I have one loop which is constantly aquiring data from my device, and I have another loop (event) which one of the events is using the same device.

What I'm looking for is a way to stop the aquiring in the first loop, wait for it to finish its iteration and then start the event

someone?

Hi,

Notifiers or semaphore are a good way to talk between parallel loops.

What are you doing in this event?

Another option is to use a queue to send the event information down to the DAQ loop.  When you get a message, perform the operation.  If you don't, behave as normal.  This is also a good way to tell the DAQ loop to stop.
