Simple LED access demo

Still the demo uses all found IO-Warriors in parallel and accounts
for the different ports the LEDs are connected on IO-Warrior 24, 40 and 56.

This is the best program for the initial test of a freshly assembled IO-Warrior Starter Kit.
If the LEDs light up then the soldering was successful.
The IO-Warrior 24 Starter Kit only has one LED which is assigned to the fourth LED button from the right.
For the IO-Warrior 56 Starter Kit it iis the leftmost LED button.

Since the IO pins are read, the button of the IO-Warrior can be tested also.
The rightmost bit should change to 0 on button press. The read is limited to the first IO-Warrior found.
