Add button to turn on light (relay)

Hey all:

LinuxCNC 2.8.4, Debian 10, Probe Basic, Mesa 7i76e card

I have a work light running through a relay controlled by the Mesa card.    In QT Dragon and Axis, I was able to create a button that turned the worklight on the mill on and off.   Any idea how to do this in Probe Basic? 

Thanks.

Yeah, but I'm looking for the satisifaction.

have a look at how qtplasmac does it. It allows you to define a number of buttons...

The progress so far:

I successfully added a hal button in QT Designer for the light.    However, when I add the line to the custom.hal file:
net Light => qtpyvcp.Light
I get a message that it can't find the qtpyvcp.Light pin.


 

I figured it out.

If you follow the instructions to install the developement install of probe basic, the postgui hal file is time.hal (which should be in your machine config folder.

In qtdesigner, I created a hal button, made it checkable, and put in the "pinbasename" field "worklight"
in time.hal, I added the line
net Light =< qtpyvcp.worklight.checked.

in the machine hal file, I connected Light to the appropriate output of my mesa card.
