Parallel Port Pins High/Low

[Chaemelion]

I know there have been a few discussions here about parallel port support, but as far as I can tell, they're all about actually connecting devices to them. I was wondering if it'd be possible in upcoming releases add a function to set/read parallel port pins.

Yeah i had the same problem so I decided to code a plugin for that.
It is very fundamental and it is my first piece of code in python after a few minutes reading the docs, so don't be supprised that i am using the bitvector class i downloaded somewhere to do the bitcalculations - quick and dirty.
As LPT "driver" I am using the Inpout32 DLL which you can find here http://logix4u.net/Legacy_Ports/Paralle ... NT/XP.html. Just put it into the folder of your EventGhost executable.

[EDIT]I think i forgot to atach the plugin[/EDIT]

Nice plugin!

Could you please explain how to read the pins?
(Want to see if my garagedoor is open or closed)

Hi,

Nice plugin!

(Want to see if my garagedoor is open or closed)

I think, a event will be generated, if the status of a pin is changed. The event name should be something like "LPT IN CHANGED [I/O status]"


If you want to read the bit, a following command should be added to the plugin (at the end):

Code: Select all

class Read(eg.ActionBase):
    name = "Reads the Bits"
    description = "You won't guess what this action does."

    def __call__(self):
        return self.inpout.Inp32(0x379)

After the line 19 following instruction must be inserted:

Code: Select all

        self.AddAction(Read)

If haven't checked it, I have only modified the given code in the way, which should work.

Thanks!

I hope I can give it a try in the weekend.

i'm using the plugin now for a while,
i tryd to edit this plugin a little this is the part i want to edit:

Code: Select all

    
def ThreadLoop(self, stopThreadEvent):
   while not stopThreadEvent.isSet():
      input = self.inpout.Inp32(0x379)
      if self.oldInput != input:
         self.oldInput = input
         self.TriggerEvent("LPT IN CHANGED " + str(input))
         stopThreadEvent.wait(0.1)

i want it to change in this:

Code: Select all

    
def ThreadLoop(self, stopThreadEvent):
   while not stopThreadEvent.isSet():
      input = self.inpout.Inp32(0x379)
      if self.oldInput != input:
         self.oldInput = input
         if input == 63:
           self.TriggerEvent("LPT PIN 63 is on")
        else:
          self.TriggerEvent("LPT IN CHANGED " + str(input))
         stopThreadEvent.wait(0.1)

i get this error:

Code: Select all

Traceback (most recent call last) (1462):
  File "C:\Program Files\EventGhost\eg\Classes\PluginManager.py", line 178, in LoadPluginInfo
  File "C:\Program Files\EventGhost\eg\Classes\PluginInfo.py", line 126, in ImportPlugin
  File "C:\Program Files\EventGhost\plugins\LPT\__init__.py", line 51
    if input == 63:
   ^
IndentationError: unexpected indent

i'm new to phyton script so excuse me if it is something stupid
thanks in advanced

The else-statement must start in the same column as the if-statement it belongs to. In your case i think it must be

Code: Select all

    
def ThreadLoop(self, stopThreadEvent):
   while not stopThreadEvent.isSet():
      input = self.inpout.Inp32(0x379)
      if self.oldInput != input:
         self.oldInput = input
         if input == 63:
           self.TriggerEvent("LPT PIN 63 is on")
         else:
           self.TriggerEvent("LPT IN CHANGED " + str(input))
         stopThreadEvent.wait(0.1)

thanks that worked!

can I use this plugin with a ParallelPort Relay Controller?

[Tal56]

Also interested in doing this with a parallel port relay I saw on Ebay, anyone know if this should work? Thanks
