Are you trying to operate a CNC machine, or something less conventional?
There is generally no direct connection between the GUI and the HAL
layer where the drivers run.

That is pretty much it, yes.

Hello again. I've looked through all the examples you've given me, and it
seems that "comp" usage is the easiest and most well-written one. So I
guess all I have to do is to fix it a little and to pass the "base
addresses" for each GPIO I need to it and to fix the array sizes according
to the numbe
Paul,
you might want to take inspiration from existing HAL GPIO drivers:

Raspberry Pi:

You'll need a HAL driver for your GPIO pins. Once you have that
Hello, I am running LinuxCNC on an ARM9 board which was no LTP but has GPIO
pins, so I've been wondering is there any way to create a mill
configuration to use them to control stepper motors.
