Default Demo Page and the real world

Hi Cybertek007,

Yes, lots of people are hooking this up to the real world. We have people driving other computers, robots, watering systems and other devices. You can wire up those buttons to any code you wish in Local.py as described in the documentation. They are not connected to anything in the demo.


Here is the code for a button that blinks an LED connected to a GPIO pin on the Pi. It is a good example of how to do this.  Add this to your Local.py file as described in the documentation.


       # object Type match
       if (objectType == ACTION_BUTTON_UITYPE):

               if (Config.debug()):
                       print "ACTION_BUTTON_UTYPE of %s found" % objectServerID

               # B-2 - flash an LED on the Pi, located on GPIO 25
               if (objectServerID == "B-2"):

                       #check for validate request
                       # validate allows RasPiConnect to verify this object is here
                       if (validate == "YES"):
                               outgoingXMLData += Validate.buildValidateResponse("YES")
                               outgoingXMLData += BuildResponse.buildFooter()
                               return outgoingXMLData

                       # not validate request, so execute

                       GPIO.setup(22, GPIO.OUT)
                       GPIO.output(22, False)
                       time.sleep(0.5)
                       GPIO.output(22, True)


                       responseData = "OK"
                       outgoingXMLData += BuildResponse.buildResponse(responseData)
                       outgoingXMLData += BuildResponse.buildFooter()
                       return outgoingXMLData


Hope that helps!

Best regards,
