Cannot import grabserial as python module #11

Closed ghost closed 8 years ago

ghost commented 8 years ago

Hello! I ran the build and the install command for the setup.py, but cannot import grabserial as a module in a python script. I am new to python and a bit lost. Grabserial works amazingly from the terminal and is the only tool to read the values reliably, it would be super cool to be able to use it inside my python script. Thanks a lot for any help! :) Andre

grabserial was really not written to be used as a python module, but rather as a standalone program.

However, having said that, it's relatively easy to convert it into a module. I'm working on an update now that should allow this. I hope to have it done by the end of the day.

OK - I've made some changes to support this. Please see the latest version (1.9.1). I haven't figured out what's going on with the setup.py script. (This was contributed someone, and I've never understood the details very well.) When you do 'sudo python setup.py install', it puts an 'egg' file in the site-packages directory, but it should be a .py file.

You can manually put this where it's needed just by copying grabserial and adding the .py extension. I'm note sure where the site-packages are for the raspberry pi release, but here's what I did on Ubuntu 14.04: sudo cp grabserial /usr/local/lib/python2.7/dist-packages/grabserial.py

Then from inside a python script (or the python intrpreter), I can do this: import grabserial grabserial.grab(["-d", "/dev/ttyACM1", "-o", "bootlog"])

It's klunky, but it appears to work. If you can help me fix up the setup.py to correctly unpack the egg into a .py in the site-package directory, that'd be great. But if not, that's fine. I'll do some digging and see if I can figure out how to do this.
