parport observation in outport out-inverter-1 seems not to work

2.9.7 I can't manage to start a configuration with inverted output ports.

pin 1-14-17 out-inverter-1 seems not to work

I can change state, but I can't start a setup with an inverted state

Weird.

Try creating a new config with StepConf and look at the HAL file(s) it generates or look at the hal file(s) in an example config to make sure your syntax is correct.

video     That's what I did when I ran into the problem

"out-inverter-1" should be: "pin-01-out-invert" (in the title)

Try setting pin-01-out-invert to 0 instead of 1.

Perhaps 1 is the default value.

Check all the HAL files in case the stuff in another file is messing stuff up.

I tried what you suggested, it doesn’t work, it has erratic behavior. It performs poorly in 2.8, 2.94, and 2.97, it behaves erratically in all of them, I don’t understand what’s going on

At startup, the system,(for example the pin 1-out) does not change when an inverter is applied.
You can watch the video I uploaded in this thread to see what happens

"Erratic" means "changing and unpredictable".

The behavior of your system seems to be predictable.

I'm a bit confused, if I want to start the system with an output at 1, do I apply setp... inverter true

This should show me the output activated, but I don't see it that way; I still see it turned off. I don't know if I'm misinterpreting it or if it's not working for me, which is why I left a video showing it.

I think you may be misinterpreting how the invert parameter operates,
it does not change the state of the parport.0.pin-NN-out hal pin.
(It cannot as this hal pin would be driven by a hal signal)
but rather changes the physical output polarity. You cannot
detect this change in the parport.0.pin-NN-out hal pin but only by
measuring the actual parallel port hardware output pin.
