[Pythonmac-SIG] Virtual Serial/USB Port
Hi all, I am trying to write a python program to "emulate" a USB GPS device on my Mac, is there anyway this is possible via Python? Basically I have something running over the network to tell my Mac its GPS location. The application I have running is listening to the data from the network and then I want that data be pushed onto a "virtual" USB GPS device. The data I will send out of it will be the standard NMEA data for any navigation software on a Mac (e.g. RouteBuddy) to read. Would anyone know how to create this "virtual port" through python?

[Pythonmac-SIG] Problem with py2app and pygame on OS X Leopard (10.5.6)
I can't seem to get py2app to work with pygame. I'm testing by just trying
to compile a simple hello world app: .
> '''A simple app that displays "Hello, world!" the title bar of its
> window.'''
import pygame
> quit = False
pygame.init()
screen = pygame.display.set_mode((640, 480))
pygame.display.set_caption('Hello, world!')
> while not quit:
pygame.event.pump()
for event in [pygame.event.wait()] + pygame.event.get():
if event.type == pygame.QUIT: quit = True
I ran py2applet --make-setup hello_world.py to make the setup.py, and it
looks like this:
"""
This is a setup.py script generated by py2applet
> Usage:
python setup.py py2app
"""
> from setuptools import setup
> APP = ['hello_world.py']
DATA_FILES = []
OPTIONS = {'argv_emulation': True}
setup(
app=APP,
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)
Running "python setup.py py2app" now seems to work fine with no errors,
however, when I run the app I get this error message:
hello_world Error
"An unexpected error has occured during execution of the main script
ImportError: PyObjC 1.2 or later is required to use pygame on Mac OS X.
> http://pygame.org/wiki/PyObjC
(Leopard comes with PyObjC 2.0 and I haven't uninstalled it.)
If I run "python setup.py py2app -A", I get:
hello_world Error
"An unexpected error has occured during execution of the main script
ImportError: No module named pygame
Any ideas on how to fix this? This app runs fine on my machine by running
"python hello_world.py", and py2app seems to work with another test app I
tried using pyglet.

I'm not sure I completely understand what you want to achieve, but it might be worth looking at the python code in the gpsd package of programs. One of those programs, possibly gpsfake, may either do what you want, or at least give some good ideas. http://gpsd.berlios.de/ http://gpsd.berlios.de/gpsfake.html -- Kevin Horton Ottawa, Canada ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
