Yes, I thought of trying that late last night - will try it later today.
I can't find "spool-step" anywhere in the docs. Is this information documented anywhere? The Hal manual doesn't address the "parport" in any detail. The naming convention is there, but no examples. I'll go look in the Integrator Manual and see what I can find.

If you look in the first Glade/Python tutorial at the destroy part and add the hal unload that should take care of that part.

net spool-step parport.0.pin-02-out <= stepgen.0.step

The Integrator manual has the
parallel port driver
in it. A signal name can be almost anything you like... see
this chapter
from the Hal Manual.

Ok, so following the "net" command syntax in the Hal manual:
net <direction>* <signal-name> <direction>* <pin-name> (<pin-name>|<direction>)*
net both-home-y <= parport.0.pin-11-in
This is where I'm getting confused - in the above example:
"net" = hal command
"both-home-y" = direction and signal name? Or just signal name?
Or are they saying that <direction>* is just an option at that point in the command sequence?
net <direction>* <signal-name> <direction>* <pin-name> (<pin-name>|<direction>)*
net both-home-y <= parport.0.pin-11-in

Directions are all optional. I have actually stopped using them in my own hand-crafted HAL.

Ah, ok, that's interesting - thanks for the info. I wish I could play with this right now, but the day job is getting in the way.

Where did you find that confusing description? Oh Never Mind, I found that...

So, I think I have it cleared up now. In the example:
net <direction>* <signal-name> <direction>* <pin-name> (<pin-name>|<direction>)*
net both-home-y <= parport.0.pin-11-in
<direction> would always be one of these "<=" or "=>". So, in the above example, "both-home-y" is the signal-name that receives an input from parport pin 11.
net <direction>* <signal-name> <direction>* <pin-name> (<pin-name>|<direction>)*
net both-home-y <= parport.0.pin-11-in
<direction> would always be one of these "<=" or "=>". So, in the above example, "both-home-y" is the signal-name that receives an input from parport pin 11.

Yep you have broken the confusing code in that bad example, I've already fixed that example and it should be online in an hour with a much better example and explication.
The signal name can only have one pin that changes it's state or value, but can have as many pins as you need that read that value.
For example
net start-button stepgen.0.enable <= parport.pin-11-in
net start-button stepgen.1.enable
The net start-button can be used more than once but only once with a Direction OUT pin like the parallel port physical in pin.
The same thing can be written as
net start-button stepgen.0.enable stepgen.1.enable parport.pin-11-in
and the direction indicators <=, =>, and <=> mean nothing to HAL and are only there for your visual pleasure.

wd5jwy,
Just for fun I created a component to work with the spooler that makes the stepper run to the max then reverse direction and run back to the min setting at the velocity set by the spin box. The green bar shows the current step count from the stepgen. So with this you don't need a mechanical reversing mechanism like a deep sea reel, just a guide on a screw...

This is an update to spooler.comp
This will update the velocity all the time so if you change it the effect will be immediate.
Thanks to bpuk on the IRC for the update.

component spooler;
pin in signed min_limit;
pin in signed max_limit;
pin in float vel_in;
pin in signed step_counts;
pin out float vel_out;
variable int direction;

FUNCTION(_)
{
if(step_counts <= min_limit){direction = 0;}
if(step_counts >= max_limit){direction = 1;}
if(direction) {vel_out = -vel_in;}
else {vel_out = vel_in;}
}This will update the velocity all the time so if you change it the effect will be immediate.
