I've used the stepconf wizard to assign to DB25-17. The hal file ends up with this:
loadrt charge_pump net estop-out charge-pump.enable iocontrol.0.user-enable-out net charge-pump <= charge-pump.out addf charge-pump base-thread net charge-pump => parport.0.pin-17-out net estop-out <= iocontrol.0.user-enable-out net estop-ext => iocontrol.0.emc-enable-in A scope on the DB-25 pin 17 does not show any sort of pulse stream. I know the signal is making it from the PC out to the Breakout board because if I assign pin 17 to say coolant instead of charge pump I can click on the flood on check box and toggle the flood output signal. If I understand the hal file correctly the charge pump code is loaded, the estop_out pin and charge-pump.enable are dependent on the user-enable-out which is controlled by the ENABLE button on the top left part of the screen. The charge-pump variable is set with charge-pump.out And the charge-pump variable is put out to the pin-17. I can delete all those lines and then run stepconf wizard which recreates what I have above. I think I'm doing everything mentioned here. http://wiki.linuxcnc.org/cgi-bin/wiki.pl?About_Charge_Pumps What's missing to enable charge pump?
