Toggle Signal as CNC Softwaredetection

Hi @ All!

I designed a CNC interface which detects if the CNC Software is running or not, to protect my machine from undefined movements when the pc is starting or the software is not running.
I need to toggle one of the output Pins with 300Hz and if my Interface detect this signal, the enable for the spindle and for the motor drivers would be given.

Is there any way to produce such a 300Hz toggle signal, as soon as Linunx CNC has startet?

I am quite shure it is possible, but don`t know ecaxtly where.

Thanks a lot and best regard!!

look at this: linuxcnc.org/docs/devel/html/man/man9/charge_pump.9.html

also siggen

linuxcnc.org/docs/devel/html/man/man9/siggen.9.html

Ok that is exactly what I need! Thanks a lot guys!!

I have to write this in the hal file right? But which way can I connect it with the right pin on the Parallelport?
And starts this signal as soon as Linunx CNC is startet, or have I to define that?

I found something there:

wiki.linuxcnc.org/cgi-bin/wiki.pl?About_Charge_Pumps

I only have to write that in the Hal.ini file right?

I would try it this way

Thanks a lot guys!!

I now have programmed the code below in the hal file. It works perfectly


Best regards
