A pin created by a python userspace component can be linked to a signal with the "net" command, just like any other HAL pin.
The documentation shows that Python Userspace Components create pins: http://linuxcnc.org/docs/2.7/html/hal/halmodule.html .. but it does not explicitly state to "net" the pins to do useful things. Here is an example that shows that the output of a Python component can be hooked to the input of a realtime component (abs): halcmd: loadusr passthrough halcmd: loadrt abs halcmd: loadrt threads halcmd: addf abs.0 thread1 halcmd: start halcmd: net v passthrough.out abs.0.in halcmd: setp passthrough.in -3.14 halcmd: show pin Component Pins: Owner Type Dir Value Name 12 float IN -3.14 abs.0.in <== v 12 bit OUT TRUE abs.0.is-negative 12 bit OUT FALSE abs.0.is-positive 12 float OUT 3.14 abs.0.out 12 bit OUT TRUE abs.0.sign 12 s32 OUT 378 abs.0.time 4 float IN -3.14 passthrough.in 4 float OUT -3.14 passthrough.out ==> v 16 s32 OUT 378 thread1.time Jeff ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
