# PULSOUT Example

Syntax: PULSOUT

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

    ' PULSOUT.BS1
    ' This program blinks an LED on for 25 ms at 1-second intervals. Connect an
    ' LED (active-low) to I/O pin 0.

    ' {$STAMP BS1}
    ' {$PBASIC 1.0}

    Setup:
      HIGH 0                                ' make P0 high (LED off)

    Main:
      PULSOUT 0, 2500                       ' flash LED for 25 ms
      PAUSE 1000                            ' one second delay
      GOTO Main
      END

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.

    ' PULSOUT.BS2
    ' This program blinks an LED on for 25 ms at 1-second intervals. Connect an
    ' LED (active-low) to I/O pin 0.

    ' {$STAMP BS2}
    ' {$PBASIC 2.5}

    #SELECT $STAMP
      #CASE BS2, BS2E, BS2PE
        Scale       CON     500             ' to ms for 2 us per unit
      #CASE BS2SX, BS2P, BS2PX
        Scale       CON     1250            ' to ms for 0.8 us per unit
    #ENDSELECT

    Flash           CON     25 * Scale      ' 25 milliseconds

    Setup:
      HIGH 0                                ' make P0 high (LED off)

    Main:
      PULSOUT 0, Flash                      ' flash LED
      PAUSE 1000                            ' one second delay
      GOTO Main
      END
