Cycle Start / Pause / Resume-Button

Hey Guys,
im using one single button to pause/resume at the moment.
Is it possible to use that one button to start the program too?
I did not really found any source how i could add a 3rd check for halui.program.is-idle

At the moment my config looks like that:

# External Program Pause/Resume Button
net pause-resume-btn and2.0.in0 and2.1.in0 <= parport.0.pin-10-in
net pause-on toggle2nist.0.is-on and2.0.in1 <= halui.program.is-paused
net run-on and2.1.in1 <= halui.program.is-running
net pause-sig or2.0.in0 <= and2.0.out
net resume-sig or2.0.in1 <= and2.1.out
net toggle-ok toggle.0.in <= or2.0.out
net togglesig toggle2nist.0.in <= toggle.0.out
net toggleon halui.program.pause <= toggle2nist.0.on
net toggleoff halui.program.resume <= toggle2nist.0.off

Seems more common to use 2 buttons for this...

As you said you would need a new layer of checks to determine what the output of hitting the button would do, you could follow the logic you are using.
So as you said if the program is idle and the program is not paused run the program.

I got the following solution for the moment. Maybe its a help for other people. Did not find a good example via google. Thanks to the Linuxcnc-irc-chat
Only problem is, that i use the halui.programm.is-idle already and cant really figure out how to use that signal twice..
any hints?


loadrt flipflop names=flipflop_resume,flipflop_pause,flipflop_run
addf flipflop_resume servo-thread
addf flipflop_pause servo-thread
addf flipflop_run servo-thread


net button-start-pause BUTTONPIN => flipflop_pause.clk flipflop_resume.clk flipflop_run.clk
net is-paused halui.program.is-paused => flipflop_resume.data flipflop_pause.reset
net is-running halui.program.is-running => flipflop_pause.data flipflop_run.reset flipflop_resume.reset
net is-idle halui.program.is-idle => flipflop_run.data
net resume flipflop_resume.out => halui.program.resume
net pause flipflop_pause.out => halui.program.pause
net run flipflop_run.out => halui.mode.auto halui.program.run
