Assigning 2 funcitons to one button was created by czerech

Hello all!

I have a problem, and maybe you will be able to help me.

I got on free input pin on my LPT board. Is it possible to use it like that.

1. I would like to have one button on machine cassing that will do 2 things.
2. If machine is OFF, button will set machine to "on" mode
3. If machine is ON , then that button will will star the program "remrun"

Right now I have it like that, but I need to make it on one input pin

net remrun halui.mode.auto <= parport.0.pin-12-in
net remrun => halui.program.run
net machine-on <= parport.0.pin-15-in
net machine-on => halui.machine.on

Thanks in advance for help!

Best regards,
Czerech

This is something like what you will need to add to your hal file(s).
To use parallel port pin 15 for the on/run button.

loadrt oneshot count=1
loadrt and2 count=1
addf oneshot.0 servo-thread
addf and2.0 servo-thread

setp oneshot.0.rising false
setp oneshot.0.falling true
setp oneshot.0.width 2

net machine-on <= oneshot.0.out => halui.machine.on
net machine-is-on <= halui.machine.is-on => and2.0.in0  #If halui.machine.is-on is already used somewhere just link this and2 to that signal.
net on-run-btn <= parport.0.pin-15-innet => oneshot.0.in => and2.0.in1
net remrun <= and2.0.out => halui.mode.auto => halui.program.run

It is possible you may also need to debounce your parallel port input.

There is also this HAL module. (does something a bit different to what you asked for, the and2 + oneshot way is better for what you asked for
linuxcnc.org/docs/2.7/html/man/man9/multiswitch.9.html
or
linuxcnc.org/docs/2.7/html/man/man9/multiclick.9.html

I didn't have time to check it

I'm going tommorow to do it, but I dont know if I added debounce properly.

loadrt debounce cfg="1"	

addf debounce.0 base-thread

setp debounce.0.delay 10

loadrt oneshot count=1
loadrt and2 count=1
addf oneshot.0 servo-thread
addf and2.0 servo-thread

setp oneshot.0.rising false
setp oneshot.0.falling true
setp oneshot.0.width 2

net machine-on <= oneshot.0.out => halui.machine.on
net machine-is-on <= halui.machine.is-on => and2.0.in0
net on-run-btn <= parport.0.pin-15-in => oneshot.0.in => and2.0.in1
net remrun <= and2.0.out => halui.mode.auto => halui.program.run
net debounce-in <= parport.0.pin-15-in => debounce.0.0.in
net debounce.0.0.out => oneshot.0.in
net debounce.0.0.out => and2.0.in1
