Reload Program Through Pin

Where did you save the file? (ie, the Python file here:

I placed the newly created file in /usr/bin with all permissions and executable.

jake@debian-test:/usr/bin$ pwd

Don't know if this means anything but.......\


jake@debian-test:/usr/bin$ python update
RTAPI: ERROR: could not open shared memory (No such file or directory)

test_postgui.hal contains:

loadusr update count=1
# addf update servo-thread
net jake-update-backplot update.trigger <= pyvcp.update-button

I still get this:

DOS style endings.... I have seen this in other posts, I have yet to see a definitive answer on what they look like or how to find them....
I assume the warning is talking about the configurations main .ini file (in this case axis.ini which is attached) I have looked all through the file and I don't see anything out of the ordinary.

The pin existed before:

halcmd: loadusr update
halcmd: show pin
Component Pins:
Owner Type Dir Value Name
5 bit IN FALSE update.trigger


There it is....

I don't understand what your getting at here....

OK, got rid of the dos style ending..... It's really nice it doesn't tell you where it found the dos style ending - it's like an easter egg hunt after finding a text editor that will display the hidden characters.......
Why does it care anyway just ignore them.....

I also got the error to go away but it still doesn't work, so this won't work with a pyvcp type hal pin??
