I can't figure out toggle was created by kkuehn
I believe I am implementing it correctly (no errors on startup, everything functions correctly in my HAL file), but something isn't right because I'm not getting the expected output.
This is what I've been trying to do:
I've looked in HAL Meter and toggle.0.out does not change its value even when toggle.0.in does change.
This is what I've been trying to do:
loadrt toggle count=1
net toggle-btn toggle.0.in parport.0.pin-12-in
net toggle-on toggle.0.out parport.0.pin-16-outI've looked in HAL Meter and toggle.0.out does not change its value even when toggle.0.in does change.

Did you add it to a thread ?
I think toggle works when on the rising edge of an input.
So at t=0 toggle-btn toggle.0.in = 0 toggle-btn toggle.0.out=0
So at t=1 toggle-btn toggle.0.in = 1 toggle-btn toggle.0.out=1
So at t=2 toggle-btn toggle.0.in = 0 toggle-btn toggle.0.out=1
So at t=3 toggle-btn toggle.0.in = 1 toggle-btn toggle.0.out=0
So at t=4 toggle-btn toggle.0.in = 0 toggle-btn toggle.0.out=0
So at t=5 toggle-btn toggle.0.in = 1 toggle-btn toggle.0.out=1
Which seems to be the behaviour when using halrun and using setp to toggle the input bit
This is a halrun session

This works. Have it and many others running on big machine.
change ion/outs are needed.
Looks like your just missing the servo.thread

I believe I am implementing it correctly (no errors on startup, everything functions correctly in my HAL file), but something isn't right because I'm not getting the expected output.
This is what I've been trying to do:
loadrt toggle count=1 net toggle-btn toggle.0.in parport.0.pin-12-in net toggle-on toggle.0.out parport.0.pin-16-out
I've looked in HAL Meter and toggle.0.out does not change its value even when toggle.0.in does change.

loadrt toggle count=6
addf toggle.0 servo-thread
net vaccum-pedal-LH toggle.0.in <= hm2_5i25.0.7i70.1.0.input-11
net vaccum-output-LH toggle.0.out => hm2_5i25.0.7i71.1.1.output-38

Thank you very much for your help, indeed addf was what was missing. I'm a noob to HAL, but I'm picking it up quickly (I've only started working on programming my machine a few days ago).
If anyone is interested, I've programmed one of those red-yellow-green tower lights with the addition of an e-stop and a machine on button, it is working perfectly. (toggle2nist code stolen shamelessly from: www.forum.linuxcnc.org/24-hal-components...toggle-on-off-button)
