I think you are using recent master. If so this python program should give you what you want.
name it metric_status and put it in your $PATH as per: http://linuxcnc.org/docs/devel/html/hal/halmodule.html Creating Userspace Python Components - LinuxCNC.org<http://linuxcnc.org/docs/devel/html/hal/halmodule.html> linuxcnc.org A userspace component begins by creating its pins and parameters, then enters a loop which will periodically drive all the outputs from the inputs. #!/usr/bin/env python import hal from hal_glib import GStat import gobject GSTAT = GStat() def mode_changed(obj, data): h['g20'] = not data h['g21'] = data h = hal.component("metric_status") h.newpin("g20", hal.HAL_BIT, hal.HAL_OUT) h.newpin("g21", hal.HAL_BIT, hal.HAL_OUT) h.ready() GSTAT.connect("metric-mode-changed",mode_changed) # work around forced merge error GSTAT.merge() metric_new = GSTAT.old['metric'] GSTAT.emit('metric_mode_changed',metric_new) try: gobject.MainLoop().run() except KeyboardInterrupt: raise SystemExit ________________________________ From: Gene Heskett <[email protected]> Sent: April 16, 2017 12:56 AM To: [email protected] Subject: Re: [Emc-developers] view and mm/inches switching.

I think that would actually just be annoying. Since we can't trace the subroutine at all, and any errors are blamed on the parent call, at least the display changing modes could tell us the subroutine is running. Its a nearly vanishingly thin excuse to be sure though. :( Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
