no you dont need a LED see the example for a standalone HAL pin, connecting the value-changed signal, and looking at state in the signal handler: http://www.linuxcnc.org/docs/devel/html/gui/gladevcp.html#gladevcp:Adding_HAL_pins - Michael > with the class i added into hal_glib.py you can create a bit_pin, net > this with what you want into your_file.hal and play your handler. > i.e. in this way i set up a combo of two joystick buttons to start > recording my movements into g-code (yes there is also a LED on it..) and > another combo to wirite "M2" at the end of the file and increment by one > the seq number of the file. > i've found this way very useful. > Davide. > > > >> Am 24.01.2012 um 00:39 schrieb Spiderdab: >> >>> It works! >>> I don't know how much it could be useful for other, but here is the >>> modified hal_glib.py code.
