XOUT - BASIC Stamp Command Reference
first turning it completely off, then sending 10 cycles of the Dim
command. This may seem odd, but it follows the peculiar logic of the X-10
system.
Demo Program (X10.bs2)
' This program--really two program fragments--demonstrates the syntax and use of the XOUT
' command. XOUT works like pressing the buttons on an X-10 control box; first you press one
' of 16 keys to identify the unit you want to control, then you press the key for the action you
' want that unit to take (turn ON, OFF, Bright, or Dim). There are also two group-action keys,
' Lights ON and All OFF. Lights ON turns all lamp modules on without affecting appliance
' modules. All OFF turns off all modules, both lamp and appliance types. Connect the BASIC
' Stamp to a power-line interface as shown in the XOUT command description in the manual.
'{$STAMP BS2}
Zpin CON 0 ' Zero-crossing-detect pin from TW523 or PL513.
Mpin CON 1 ' Modulation-control pin to TW523 or PL513.
HouseA CON 0 ' House code: 0=A, 1=B... 15=P
Unit1 CON 0 ' Unit code: 0=1, 1=2... 15=16
Unit2 CON 1 ' Unit code 1=2.
' This first example turns a standard (appliance or non-dimmer lamp) module ON, then OFF.
' Note that once the Unit code is sent, it need not be repeated--subsequent instructions are
' understood to be addressed to that unit.
XOUT Mpin, Zpin, [HouseA\Unit1\2, HouseA\UnitOn]' Talk to Unit 1. Turn it ON.
PAUSE 1000
XOUT Mpin, Zpin, [HouseA\UnitOff]
' The next example talks to a lamp module using the dimmer feature. Dimmers go from full
' ON to dimmed OFF in 19 steps. Because dimming is relative to the current state of the
' lamp, the only guaranteed way to set a predefined brightness level is to turn the dimmer fully
' OFF, then ON, then dim to the desired level.
XOUT Mpin, Zpin, [HouseA\Unit2]
' This example shows the use of the optional Cycles argument. Here we Dim for 10 cycles.
XOUT Mpin, Zpin, [HouseA\UnitOff\2, HouseA\Dim\10]
