NAP Example

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
