Excellent thought, Roland. But to what extent can ChatGPT help? I have
just been reading that, at the moment, it essentially fetches content
from a 2021 snapshot of the internet.
So I am not clear whether the answer it has given has been lifted from a
human-generated example, or whether it can go much further in devising
an answer without, as you say, someone giving it a further description
of the parameters/constraints and the way in which HAL programming is
done (rules, I guess).
This is an interesting question, though; and I have also been reading
about the good success in having AI systems do coding.
I recall the early code-generating systems which appeared in the early
1980s, which have made great strides since then, so it makes sense that
AI systems like ChatGPT might make the benefits available to a much
wider user base, like LinuxCNC users.

So this is obviously very generic, but one can easily 'add' new
parameters/constraints to the query. By the way, I have no clue if it
is
correct or not.
Maybe someone could try troubleshooting their existing script by
pasting it
into AI and ask to check it.
Another option is for a developer to write a web page interface using
the
AI API to help users generate HAL scripts.

AI Q: write a HAL script for Linuxcnc using steppers and a 7i92
interface
card
AI A: Here is an example of a HAL script for LinuxCNC using stepper
motors
and a 7i92 interface card:
# Load the 7i92 driver
loadusr -W hal_7i92 -i0
# Declare the step and direction pins for each axis
setp stepgen.0.step_pin halui.0.axis.0.step
setp stepgen.0.dir_pin halui.0.axis.0.dir
setp stepgen.0.enable_pin halui.0.axis.0.enable
setp stepgen.1.step_pin halui.0.axis.1.step
setp stepgen.1.dir_pin halui.0.axis.1.dir
setp stepgen.1.enable_pin halui.0.axis.1.enable
# Set the maximum frequency for each axis
setp stepgen.0.maxvel 1000
setp stepgen.1.maxvel 1000
# Connect stepgen outputs to 7i92 step and direction pins
net step0-out stepgen.0.step => 7i92.0.step-0-out
net dir0-out stepgen.0.dir => 7i92.0.dir-0-out
net step1-out stepgen.1.step => 7i92.0.step-1-out
net dir1-out stepgen.1.dir => 7i92.0.dir-1-out
# Enable the stepper motors
setp halui.0.axis.0.enable 1
setp halui.0.axis.1.enable 1
This script assumes that you have already set up the hardware
connections
between your 7i92 card and stepper motors, and configured the 7i92 for
use
with LinuxCNC. Note that you may need to modify the pin assignments and
other parameters based on your specific setup.
