You know what ? You are 100% right here ! I have tested the 2
solutions, and yes, both work.
To sum-up the two solutions:
1) *** using setp ***
- custom.hal contains:
loadrt or2 count=1
addf or2.0 servo-thread
net programPause => halui.program.pause
net pause-joystick or2.0.in0 <= input.0.btn-thumb
net programPause <= or2.0.out
- and my emc_pause script is modified as follow (we address directly
the second input of the OR gate):
#!/bin/sh
halcmd setp or2.0.in1 1;
sleep 0.1
halcmd setp or2.0.in1 0;
sleep 1
halcmd setp halui.spindle.stop 1;
sleep 0.1
halcmd setp halui.spindle.stop 0;
halcmd setp halui.flood.off 1;
sleep 0.1
halcmd setp halui.flood.off 0;
echo Machine paused.
2) *** better solution: use sets (set signal) ***
- custom.hal contains:
loadrt or2 count=1
addf or2.0 servo-thread
net programPause => halui.program.pause
net pause-joystick or2.0.in0 <= input.0.btn-thumb
net pause-console or2.0.in1
net programPause <= or2.0.out
- and the beginning of my emc_pause script is modified as follow (this
time we address the signal that is connected to one of the input of
the OR gate):
#!/bin/sh
halcmd sets pause-console 1;
sleep 0.1
halcmd sets pause-console 0;
sleep 1
...
Obviously, I did the same for the emc_resume script / button. The only
difference is that we declare two OR gates (loadrt or2 count=2) and
the second one is addressed with the name "or2.1".
Note for those who are looking for more info: the html documentation
doesn't contain all the commands (eg I think that sets is missing), so
take a look at the man page of halcmd ("man halcmd").
Thanks again for your help :-)
