Step 4:  Programming the IO

To begin a new program, you should CLEAR the previous one.  You can do this with either the button or by typing clear.

For the LPC11U37 - ARM Stamp and LPC1114 the LED is connected to P0(1).  

   WHILE X<30
       IO(1) = X and 1    ' IO() sets pin direction and state
       X=X+1
       WAIT(500)
    LOOP

For the SuperPRO and PROplus. Use the following. LED is connected to P2(10).

                                 ' port 2 starts at 64
   WHILE X<30
       IO(64+10) = X and 1
       X=X+1
       WAIT(500)
    LOOP

The LED on the PCB should pulse 15 times.

To stop a running program simply press the Stop button.
