İnstall glade

It is not possible to change a parameter in the hal file from the gui. Is it true?

To set a parameter through the gui you can simply add a function to your handler.

1. add the function 'on_value_changed' to your panel handler script like this (you will need to change the parameter name form 'near_speed.difference' to whatever parameter you want to change):


 

2. Open your panel in glade and add 'on_value_changed' as handler for the 'value_changed'  signal to your widget:

 

The parameter value should now change with the value of the panel widget:
 
 

Thank you very much for your answer. I will try, but all day today I tried to change a value in the gladevcp panel from the g code content. I researched a lot, tried a lot, but I was not successful.
example
test.ngc:
#<_hal[testpanel.hal_label]> = 1.0 it's doesn't work
#<testpanel.hal_label> = 1.0 it's doesn't work
#<_hal[testpanel.hal_label]> = #100 it's doesn't work
#100 = #<_hal[testpanel.hal_spinburon-fl]> I think its work

There is no problem reading the variable, but I could not manage to change the value of the variable.

When I add this code gladevcp is not displayed in gmoccapy.

 

This is from the documentation:

#<_hal[HAL item]> Allows G-code programs to read the values of HAL pins Variable access is read-only, the only way to set HAL pins from G-code remains M62-M65, M67, M68 and custom M100-M199 codes. Note that the value read will not update in real-time, typically the value that was on the pin when the G-code program was started will be returned. It is possible to work round this by forcing a state synch. One way to do this is with a dummy M66 command: M66E0L0

When I add this code gladevcp is not displayed in gmoccapy.

Start your config from a terminal and check the output for errors.

I read it many times, but I did not understand how to send the value inside #100 to testpanel.label with m6x codes. I made the digital inputs and outputs with motion pins and I was able to understand it.

Hello,

 
 

sorry this is not this there are 2 configurations
 

I created the above configuration just to see the embedded pages, but now I have deleted it and when I run the linuxcnc -l command, it says that it cannot find my actual configuration.

Since I deleted the configuration I do not use, it cannot find that configuration. How can I run the configuration I actually use with linuxcnc -l?

It's looking for sim.gmoccapy, my configuration name is bluecad
