First PiFace Script

ge0rgej
ge0rgej over 11 years ago

Hi

 

Having problems initiating my first PiFace script. I have played around with the Wobbly Chicken script

but am unable to get the script to initiate in the PiFace emulator. The 2 associated files are below

 

http://pastebin.com/embed_js.php?i=5eb40u1S

 

http://pastebin.com/embed_js.php?i=ZWAzfJC5

 

 

Using TightVNCServer ... at the command prompt I am typing 

 

python Tank_Autofill.py

 

but all I am getting is the following error -  xlib: extension "RANDR" missing on display ":1.0".

.... and the emulator does not initiate

 

If I run the piface_test.py that is provided in the piface/python/tests folder ... the emulator / script works

 

I'm guessing that something is wrong with my coding - any help would be much appreciated

    ok - I've just realised that raspberry_pi_farm should be replaced with Tank_AutoFill

     

    but now I am getting the following error message

     

    /usr/lib/python2.7dist-packages/gtk-2.0/gtk/_init_.py:57: GtkWarning: could not open display

    warnings.warn(str(e),_gtk.Warning)

     

    Again - help appreciated

    Hi,

    You're using out of date libraries. You might find it easier to use the new software available here: https://github.com/piface/pifacedigitalio

     

    There is also documentation and some example code.
