Feedback Button programming

jwmacc,

Well, yes. It was decided to do this to remove the lower case / upper case conundrum. And no, it isn't documented anywhere, but it will be shortly!   I've got to go look through the Feedback button code in the App and figure out what it does so I can put it in the RTFH!


Here's an example of the code that we use.  Note that we convert the Button name into lower case, do our comparisons and the convert back to "title" format with:  responseData = responseData.title()

The state of the Fan is in a file so other processes can read the current fan state.  The default section is there because there is a possibility in the case of an Internet hiccup the button can go blank.



This is a section of code that toggles a Fan on and off on GPIO18.


# FB-12 - turn on GPIO 18 (fan)
if (objectServerID == "FB-12"):

                #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

              responseData = "XXX"
if (objectName is None):
objectName = "XXX"

              lowername = objectName.lower()

GPIO.setmode(GPIO.BOARD)

                if (lowername == "turn fan on"):

GPIO.setup(18, GPIO.OUT)
GPIO.output(18, True)
time.sleep(0.3)
GPIO.output(18, False)

                f = open("/home/pi/ProjectCuracao/main/state/fanstate.txt", "w")
                f.write("1")
                f.close()


                        responseData = "turn fan off"
                        responseData = responseData.title()


                elif (lowername == "turn fan off"):

GPIO.setup(15, GPIO.OUT)
GPIO.output(15, True)
time.sleep(0.3)
GPIO.output(15, False)
                f = open("/home/pi/ProjectCuracao/main/state/fanstate.txt", "w")
                f.write("0")
                f.close()

                        responseData = "turn fan on"
                        responseData = responseData.title()


# defaults to fan on (meaning fan is off)
                else:
                        lowername = "turn fan on"
GPIO.setup(15, GPIO.OUT)
GPIO.output(15, True)
time.sleep(0.3)
GPIO.output(15, False)
                f = open("/home/pi/ProjectCuracao/main/state/fanstate.txt", "w")
                f.write("0")
                f.close()

                        responseData = lowername.title()


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



Hope this helps!  And thanks for pointing out the RTFH deficiency.

Best Regards,
