Now I've another data missmatch, since when is a "not" not a true/false

What is the datatype of your mux2?
float ack the man 9 page
However in thinking thru that paragragh of hal code, its all bit from
the input from the drivers on, to there and effectively so is the halui
input that bangs the e-stop off. Everything in that chain except the
mux2 is bit wise stuff. I've tested the code thru multiple times, and it
is working as designed for an f2 toggle, which also comes on in an alarm
state for about 1 second and it does block that momentary alarm just
fine. So the existing code is actually working.
The problem on the sixty40 shows at lcnc launch init, requiring an extra
hit on ctl-space to clear the messages it emmits due to the default no
power state its in at that time. So I am wondering if I can "not" the
signal and correct that later. I'll give that some thought later. Since
that output is a bit switched by an opto, the possibility of a free
inversion by rewiring comes to mind.
Future project, I've left comments in the hal file FFR. Thanks Andy
Now back to the GO704 and its missing spindir signel, which is also a
bit, But since I was running the former pwmgen in mode2, I don't think
I ever developed a dir signal because the mode2 is biplar. 2 separate
pwm signals IOW. Fun, games and headaches but it sure keeps me out of
the bars.
Thanks Andy.
Works for me:
andypugh@rm-one:~/linuxcnc-dev$ halrun
halcmd: loadrt not count=1
Note: Using POSIX realtime
halcmd: loadrt mux_generic config=bb2
halcmd: net test not.0.out mux-gen.00.in-bit-01
halcmd: show sig
Signals:
Type Value Name (linked to)
bit FALSE test
==> mux-gen.00.in-bit-01
<== not.0.out
Cheers, Gene Heskett.
