Help using comp

Thanks ArcEye,

I did heed your warning about spurious characters in the "comp" file but I couldn't tell what belonged
and what didn't.

I installed your copy and it seems to work. I'm missing at least one shared library (libenchal.so.0) so will
try to find the source code.

Thanks for the tip on "loadusr". That made "hal" recognize the component.

Will be gone the rest of the day but will work on it tonight.

Thanks again,
Don

It appears that:
libemchal.so.0 has been replaced by liblinuxcnchal.so.0
and
libemcini.so.0 has been replaced by liblinuxcncini.so.0.

I did symlinks (ln -s) from the current files to the old files which kind of worked. Linuxcnc crashes
saying it can't find "port", no such file.

I can see the Arduino at /dev/ttyACM0.

Unless someone has an idea whats going on, I will give it a rest for a while.

Thanks again,

Don

Hi

Time zone difference across the great divide, up now.

The answer to both your posts is essentially the same. This was an example program and never meant to be distributed as a compiled binary.

The library linkage is because it was compiled on a machine running a development version of linuxcnc, not the release version where everything is re-named.

I can see the Arduino at /dev/ttyACM0.

Unfortunately serialcon is looking for the arduino at /dev/ttyUSB0 because I used a duemilanove board and you are using an ATMega which has a different port default.

The address is coded as a define at the top of the code, #define DEVICE "/dev/ttyUSB0".

You will need to change that and re-compile. Your library problem will go away at that point too

Hi ArcEye,

AWESOME!

Now everything works! It never crossed my mind that the duemilanove and UNO had different
port addresses.

You have been very generous with your time and expertise. Thank you very much and Thanks
to all that jumped in to help me. This is a great forum.

I'm not much of a software guy but I do make some nice swarf.
