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)

I think I have given misleading advice.

There is no "update" function as the component is a user-space program, not a realtime component.

Ignore the "addf" line, it will never work. But the component itself ought to have the desired effect if you toggle the update.trigger pin.

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:

First, get rid of the DOS-style line endings.

The pin existed before:

There it is....

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:

5 bit IN FALSE update.trigger


There it is....

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