Last night I modified the parport driver so that the port direction is set as soon as you load the driver. (No need to run "parport.N.write" unless you are actually using the port for outputs.) The fix is in CVS HEAD, and will also be part of the 2.1 release. Thanks for calling the bug to my attention. Regards, John Kasunich - Take Surveys. Earn Cash.

Re: [Emc-users] parallel port initializing
There is a way around it if we find that Paul successfully raises the proprietary flag with the work that I encouraged him to do with qt3. Smithy Company has purchased a written from scratch version of a QT4 EMC library that will be LGPL copyright. This should be available before long.

I think it would be desirable to have them named identically in both cases. That way a user can rapidly test and refine the widget layout/HAL connections in standalone mode, and then "dock" the panel into AXIS without having to modify the HAL script.

Re: [Emc-users] parallel port initializing
I had someone mention this a while ago. I tried to find it to understand what was being mentioned, but either was looking for the wrong thing, or didn't understand what was being said. I'll try to look into it some more. The only reason I mentioned Qt is I already on the learning curve on it. It's an old saying I once learned. To a person who's only tool is a hammer, every problem has a nail head.

James, you might have noticed a recent development called pyVCP: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?PyVCP I assume your encoder counts or machine position are now HAL_FLOAT signals? If you want a HAL_FLOAT displayed on-screen without running emc you don't have to reinvent the wheel with QT3, you can do it very easily and quickly with pyvcp. currently pyvcp runs when AXIS is run, but the modifications to make it run standalone with a use-specified input file are small.

Re: [Emc-users] parallel port initializing
Well, if you must have Qt, then I think I can help you :) There was a little bit of work done on a Qt<->NML interface a couple of years ago. It never went too far, but strangely enough, the "demo app" is a DRO :) I'll dig it up and either stick it on the wiki or I can email it (or even check it into CVS somewhere). - Steve James Reed wrote: >I got Hal running as just the input for encoders.

I believe that out of 4 linux boxes I tried, two did support it and two did not. The two that did were older machines -- a Pentium II laptop and a Pentium III server. The two that didn't were newer systems -- an Athlon FX desktop and a Pentium M laptop. jeff - Take Surveys. Earn Cash.

Sorry if I'm repeating stuff you already know, but I'm just making sure. Pins 2-9 can be configured as inputs or outputs. Pins 10, 11, 12, 13, and 15 are always inputs. And pins 1, 14, 16, and 17 are (almost) always ouputs. To use pins 2-9 as inputs, you need to specify "i" or "in" in the config string when you load the driver. To use pins 1, 14, 16, and 17 as inputs, you first need a parport that supports it, not all do. Then you need to specify "x" in the config string. And finally, you need to set the corresponding outputs high. The ports that support input on those pins do so by using open-collector drivers that can pull down but not up. If you set them high, there is an internal pullup resistor that pulls the pin high, but it can be overcome by an external source to read a low input. You should not attempt to force these pins high if they are being driven low. Using pins 1, 14, 16, and 17 as inputs should be considered experimental. I don't think it is supported at all in version 2.0.x, so unless you are running code from CVS, ignore this entire paragraph. > My question is this? When in the program does parport get initialized to > inputs, and how do I make sure it is initialized before I try to drive it? The direction of pins 2-9 is set when the parport.N.write is executed. So you must "addf" it to a realtime thread, and start the thread, even if you don't intend to use any outputs. (This might be a bug - I will look into setting the port direction as soon as the driver is loaded.) > Thanks for your help. Hope this is usefull, let us know what you find out.
