WHB04B-4 Lead Switch Issue

I see you patched these two functions

void Pendant::dispatchFeedEventToHandwheel(const KeyCode& feed, bool isActive)
void Pendant::dispatchActiveFeedToHal(const KeyCode& feed, bool isActive)

When I  look at the value of key.code when I turn the knob to lead, the value is always 0x00 so your || condition key.code == 0x96 is never true

I think line 337 in FeedRotaryButtonCodes::FeedRotaryButtonCodes() :

undefined(0x00, "", ""),

sets the key code to 0x00 because 0x9B is not in the table for permisable values.

I made changes like in the following files and it seems to work for me. I renamed pendant.cc to pendant.txt as the forums do not allow .cc files for some reason.

Hi Slammers

I'm facing very similar issues with my wh04b-4, I would greatly appreciate it if you can help me figure out how to compile this driver.  I want to make to various changes to the source. I'm happy enough with making the changes - its the compile process that's new to me.

Thanks Bally
 

What is I just give your the compiled file? I guess that would only work if you are using the same revision of LinuxCNC that I have. Which is 2.8.

 

Hi 

That would be appreciated and my working machine is on 2.8. 

But ultimately I'd really like to be developing the source code to suit my needs going forward. In addition to the lead switch I want to change other things. 

I created a topic earlier regarding all my issues and thoughts, then found this topic later on.

My SIM machine is on 2.9 and it's only a matter of time before I move to that so being able to compile my changes is really the ideal situation.

But in meantime yes I would glady appreciate your file.

Thanks Bally

Have you read the help on compiling LinuxCNC? This should be all you need. These are the instructional I followed.

linuxcnc.org/docs/master/html/code/building-linuxcnc.html

The only real headache was the step

dpkg-checkbuilddeps

as there were tons of dependacies I had to add to my system. Both once they are all installed the build process worked fine.
