Greetings all;
While I can make a CP detector with 2 caps, 2 diodes and a load resistor,
and have 2 of them in service ATM, it strikes me that someone ought to
be making them, several up on a PCB.

If you cannot see the signal on pin 17 of your
parallel port using an real oscilloscope, then
you may have issues with your HAL file bringing
the signal to the actual output pin.
If I can see a signal on halscope what in my hal file would prevent it from
occurring on the physical I/O? My axis

I have a new PMDX Gecko driver board. It requires an osculating +5 to 0 to

Ah, the fog is clearing. I hadn't grasped the relationship between
loadrt and addf. So basically loadrt initializes the module then addf
connects it to a thread and runs it.

I used an oscilloscope to look at the pin and nothing was coming out.
Looking at the hal file, it looks like stepconf didn't connect the
