Thread Subject: Function Execution at the same time

Good Morning,

I'm using GUI to manage with an application. This simple
application has two buttons; the first activates a while
loop changing the status of a serial port to obtain a
square wave, the second call a function that looks for the
HI_LO change state of the pin of the serial port to
execute. I tried to do this bus the program stops every
time i push the second button. I think this is a problem
about the contemporaneity of the execution. Is there a way
to execute different thread at the same time using one only
Matlab session?

Thanks,
Marco Francini.

1/ While with pause function

   In the while loop, put pause function for .01 or .1 second.
   while 1
      . . . .
      . . .
      pause(0.1)
   end

2/ Timer
   using timer to perform your code with start and stop
   function instead of while loop.
   
   help timer
   help start
   help stop
