Execute two loops alternately

[anouardz]

Hello,

I want to execute a loop in 1 second then a second loop for 1 second and that's repeated before pressing the button stops. if you can give me some examples it will be better.

Can you give us more detail on what you are trying to accomplish?

[anouardz]

 I want to read and save in tdms file the analog input A0 for 1 second and the analog input A1 for 1 second in daq 6008, but not simultaneously. and that's repeated before pressing the button stops

Something like this?

This is the best I can do without more information.

[anouardz]

this 3 loops, are they a while loops?

What you need is a state machine that execute state A then state B until the stop button is pressed.

yes, but not simultaneously

[anouardz]

yes, but not simultaneously

I think it would be simpler to just acquire both channels and alternatively write to your separate files. You need to stop and clear each task before starting another.

You should always quote the previous post, because it is not clear what you are replying to.

A state machine is the correct architecture, only one loop needed. Simply switch states every desired time interval.

Don't gum up the gears with loops inside loops, etc. It makes the code hard to manage and hard to add functionality later and hard to branch out in case of problems or exceptions.
