PyTrack not working with Processing



  • Hello, I'm getting started with PyTrack and trying out the accelerometer example. I am able to output the accelerometer data in PyMakr in Atom, however Iget an error when I run the visualizer in Processing:

    I figured it had something to do with the jssc library and tried installing jssc. I extracted the files from jssc.jar and moved the files from jssc/lib/linux into ~/.jssc/linux but I still get the same error. I'm currently at a loss.

    Also, I'm on Manjaro linux.

    Any help would be appreciated!



  • @paul-thornton Ok thanks for the reply!

    I presume atom is closed/not connected when your trying to connect via Processing.
    (Altho UnsatisfiedLinkError suggests its not just a case of the port being busy).

    Sadly I think this is more suited for Processing's support forums than It is here as the problem seems to lie outside of Pycoms control, That said Ill leave this thread open and perhaps someone might be able to help :)
