Hello, I am doing a project in school with a computer running Ubuntu 8.04 and python 2.5. we would like to control a circuit board via the computer's parallel port. On windows with python and pyparallel installed typing
p = parallel.Parallel()will let us write to the parallel port. In ubuntu however I am having some trouble. first I was getting an error about permission denied so I ran my script as sudo but now I get this error:
>>>p = parallel.Parallel()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/site-packages/parallel/parallelppdev.py", line 186, in __init__
self._fd = os.open(self.device, os.O_RDWR)
OSError: [Errno 2] No such file or directory: '/dev/parport0'In google I found that I should type:
sudo rmmod lp
sudo modprobe ppdevBut I still get the error about it not existing.
In other treads they say to use "/dev/lp0" or a range of other things in "/dev/" but that isn't working either.
My question is:
Is there something that needs to be modded in Ubuntu? and how? And, how do you specify a port? p = parallel.Parallel("/dev/otherport") or something different?
