XHC-HB04 wireless MPG pendant HAL module

I run 2.6.0-pre without problem.
Have you tried to recompile the xhc-hb04 module ?
Use
make clean
make
make install

I did exactly that on first time error showed up.
For installing Run In Place Linuxcnc I followed this steps ... wiki.linuxcnc.org/cgi-bin/wiki.pl?Instal..._or_8_04_from_source
Or maybe 2.6.0-pre could be installed any other way? Because I also have had to copy kinematics file from "standard" installation to folder where I have run in place "installation" to make it run...


If it helps, here are debug and print files:

Try the ldd command to see what lib are used by xhc-hb04.
Here is what it prints on my machine

I suspect issue with liblinuxcncini.so.0 on your machine.
I do not know how "run in place" works.
I use buildbot packages ( buildbot.linuxcnc.org/ ) but the upgrade from 2.5.2 was painful because of remaining python modules on my setup. May be some mistake during upgrade phase on my side.

I would first say, thank you for sharing this component. It was easy to set up and get it to work.
It works very well.
Only two small problems found.

First, if running spindle very slow there is quite big rounding error in rpm on display. Changing code row to solves that problem.

Second problem is, sometimes, DRO can show 1 number off.
For example, zero x-axis and move exact 1mm it still show 0.000. If move 1 more it shows 1.000. This up to 5, there it was correct.
If running in oposite direction, it showed correct.
If moving 1/10mm from zero, it showed correct 0.1, 0.2, 0.3 etc up to 0.9. Then when it is 1.0, dro show 0.0000. 1.1 was OK again.
When looking at hal pin, position wasn't 1.000, it was 0.9999999...
I changed in xhc_encode_float function to this and now it looks like it shows correct values.

One other good thing to now is that some versions of LinuxCNC halui.axis.0.pos-relative dosn't apply tool offset. I had that problem first running on a quite old version of 2.6.0-pre. Pulled latest from git and it worked correct.

I just wanted to share my findings.
Thanks again for sharing this component to us. It helped me a lot!

Everything looks ok
if xhc-hb04 runs in test mode (launched from the shell), then there may be something wrong in path used by linuxcnc. You can search in your filesystem if there is another liblinuxcncini and remove it, or fix linuxcnc path.
