Hey guys -


The project I'm working on needs a simple wait timer but most of the execution of the program is in a do...while loop.  I don't want to put a thread.sleep because then I might miss a command in the do while.  


Played with the timer class some but really just need a once and done - I like the idea of an interrupt being raised -  I'm a complete noob when it comes to code -   


Anybody have a good suggestion?

Hi Jeff,

The Timer class constructor takes both dueTime (time to first timer call) and period (time between each timer call).

Just set the period to zero...and your timer will be called exactly once.

Does that get you on the right path?

I think you need:

Thread.Sleep( SECONDS  * 1000 ) as wait state.


And about timers:  In visual Basic you can program a timer very easy:
example of a reset timer (but is can do anything) together with a class:

Dim reset As New resetNetduino
Dim tcb As TimerCallback = AddressOf reset.reset

Dim resetTimer As Timer = New Timer(tcb, Nothing, 50000, Timeout.Infinite)

'bla bla bla code.....
'now dispose the timer, if you do not  dispose, reset of the Netduino will follow after 50 secs !

Public Class resetNetduino

' This do nothing but init.
Sub New()
End Sub

' This method is called by the timer delegate.
Sub reset(stateInfo As Object)
End Sub

End Class
