This is a little parallel port tester done with pyVCP.

To run this place both files in the same directory and open a terminal window and use the command
halrun -I -f ptest.hal

You can push the output buttons and change the state of each output. When you toggle an input it shows up on the screen.

John,

What is the switch immediately following "halrun" in the above code sequence?

Thanks

I am trying to run this test. First can it be run with nothing connected to the parallel port? If so this is what happens:
When I run halrun -I -f ptest.hal I get " Waiting for component 'PortTest' to become ready" a bunch of dots and than halcmd: I also get a new blank window called PortTest., eventually every thing seems to time out and I get back the normal prompt and the blank window closes.
This may wll be something that I am doing wrong due to my ignorance of Linux.
Any help wpould be appreciated
TIA
Tony.

Yes it works with nothing pugged into the port. You have to be sure that the port adress in the 1st line of the Hal file is the same as the port you are testing.

I would use it (a slightly modified version) to test if certain ports would work work in X-mode. I would start the test then probe holes with a resistor to see if the circles changed color.

Thanks for the reply. Unfortunately it did not help. The address in the Hal file is in fact the same as the port (onboard parallel port)
Is there anything that I need to do or set up BEFORE I run the test?
TIA

Are you running this on a computer with LinuxCNC installed via the LiveCD?

It should just work...

Are both files in the same directory?

Did you open the files with a windoze editor that might have tacked on some funny stuff to the end of each line?

Here's the corrected X-mode ptest files. I fell pray to windows scrambling the xml file when I posted from my windows machine.

Yes it was installed from a Live CD 8.04 -
Yes both files in the same directory
Downloaded directly to the Linux box and used "text editor" to verify the port address.

Thanks
Tony
