# NAP Example

Syntax: NAP

Connect an LED and 470 Ω resistor as shown below for the demo program.

NOTE: The example below is written for the BS2 and will run on any of the BS2-family modules. Modify the $STAMP directive (as required) before downloading to the BS2e, BS2sx, BS2p, BS2pe, or BS2px.

    ' NAP.BS2
    ' The program below lights an LED by placing a low on pin 0. This completes
    ' the circuit from +5V, through the LED and resistor, to ground. During the
    ' NAP interval, the LED stays lit, but blinks off for a fraction of a second.
    ' This blink is caused by the NAP wakeup mechanism.  During wakeup, all pins
    ' briefly slip into input mode, effectively disconnecting them from loads.

    ' {$STAMP BS2}

    Setup:
      LOW 0                                 ' turn LED on

    Snooze:
      NAP 4                                 ' nap for 288 ms
      GOTO Snooze
      END
