Code

.. code:: python

   while : 1 == 1 {
       digital_write(P1_31, true);
       delay(1000);
       digital_write(P1_31, false);
       delay(1000);
   }

-  Following code works on PocketBeagle, to use on other boards, please
   change the pins accordingly.

Explanation
------------

This code runs a never ending loop, since it is ``while : true``. Inside
``while`` it sets header pin P1_31 to HIGH, waits for 1000ms, then sets
header pin P1_31 to LOW, then again it waits for 1000ms. This loop runs
endlessly, so we get a Blinking output if one connects a LED
