K9N2G Neo (MS-7511) Parallel port interrupt

Hi All,
I'd like to use the onboard parallel port of the K9N2G Neo (MS-7511) for a custom designed instrument. This equipment generates parallel port interrupts thus I need to run this port in IRQ driven mode. On older mobo-s BIOS usually have an IO address + IRQ setting for onboard parport, now I can only find an IO address. Any idea?
Thanks
Gabor

Sending out a signal via Parallel port in interrupt mode?

I am trying to send out a 5KHz TTL signal via parallel port. the CPU should be disturbed at most time. so we can't use loop structure. I guess I have to use interrupt mode to do this job.
In other languages, we might be able to programm 8253, which is a timer and counter chip on mother board. can we generate a 5KHz siganl via parallel port without disturbing CPU?
or can we call another labview program in our main labview program.by doing so, two programs are running at the same time, we may be able to solve my problem
Thanks

Hi Sean-
This functionality is theoretically possible, but this might not be the best option if you are concerned about latency in operation. A few references for using the parallel port in LabVIEW are linked in this thread.
If you are concerned about precise timing and operating system latency issues, you may want to consider a hardware-timed PCI counter/timer board instead. This utility is a good starting point for selecting such a card.

K9N2G Neo CPU Stepping question.

Hello, I have a K9N2G Neo and I am looking to upgrade to a AMD Phenom II X4 925 but I have a couple questions. Will stepping/revision of a CPU effect compatibility?
I see in the CPU Support that Phenom II X4 925 C2 is supported but would the same CPU but C3 stepping effect weather or not it worked with my motherboard?
K9N2G Neo CPU Support list - http://www.msi.com/index.php?func=prodcpu2&prod_no=1493&maincat_no=1 (HDX925WFK4DGI) Stepping - C2)
AMD Phenom II X4 925 - http://www.newegg.com/Product/Product.aspx?Item=N82E16819103656 (HDX925WFK4DGM) Stepping - C3)
Sorry if this is common knowledge I haven't been able to find information on it anywhere.
Thanks for your time.

Best to ask MSI. http://www.msi.com/index.php?func=html&name=aboutus
The latest in support list is C2 CPU supported by BIOS 1.2 and that dates back to Jan. 2009.
Even the list from this website which are usually fairly up to date doesn't show any C3's.
http://www.cpu-upgrade.com/mb-MSI/K9N2G_Neo_%28MS-7511%29.html
It probably is supported with latest BIOS but don't take my word for it.

[865PE/G Neo2 Series] How to correct "Parallel port driver service failed to start"?

I recently disabled the parallel port in the BIOS (I wasn't using it anyway) to try and free up an IRQ or some system resources, when I installed a firewire controller (which I wanted to have its own IRQ if possible). Then I periodically started getting this error "The Parallel port driver service failed to start due to the following error:
The service cannot be started, either because it is disabled or because it has no enabled devices associated with it." I Googled this, but any info I found either was not applicable or was in incomprehensible techspeak. I couldn't figure out how to prevent the error from occurring, so for the time being I re-enabled the parallel port in the BIOS--disabling it didn't free up any IRQ's anyway. I would like to know more about this, however. Is there a proper way to go about disabling the parallel port so that this error does not occur?
Should it be done before installing Windows? What are the advantages and disadvantages of disabling the parallel port, other than freeing up IRQ's (as I said, it didn't--unless this also happens only upon Windows install?). Gurus, please respond!

That was the first thing I tried. There is nothing called "parallel port service", nor is there any mention of the parallel port in any of the services listed. I don't know if it is even using any system resources, anyway. The ECP Printer Port always had a box checked that said "never use an interrupt" anyway. It has no conflicts or sharing. Maybe I should leave it alone. It's just that people always mention disabling it in order to free resources.

Driving stepper motor via parallel port

Hi everybody,
I want to drive a stepper motor via the parallel port. The problem is to
create a constant frequency on a digital line of the port. I tried to do
so with a While-Loop with a certain delay, but the frequency varys due
to occurrences like mouse-movement (due to the call-ups of interrupts I
think).
Any Ideas?
Regards
Martin

How about a simple NE555 timer circuit to externally create the constant
frequency, then use a bit in the parallel port to enable and disable the
NE555 circuit? You could probably go to Radio Shack and pick up the
components for less than $10.

Problem with JNI and Parallel Port dll

Hi. I'm doing some testes with JNI. Firs i followed the netbeans tutorial for doing a C programa that prints somthing for java.. like.. "Hello java from C".
So i tried to load a dll from my dll. Like, I have this dll to use the parallel port on windows Xp. So i created a dll to access it an comunicates eoth java.
I did everything just fine.
When I start my Java app, the first thing it does is to load this parallel port dll and configure the functions of it.
After that .. I get this error

Can someone explain why ?

Control parallel port (data and control lines)

I need to control the output on the parallel port (LPT1) - Both data and control lines. Once the data is written (Pins2-9), I then need to toggle the Sprocket signal (PIN1) - on the parallel port. The sprocket signal is also referred to as the Data Strobe Output.
The required method is as follows:
1. Lower the sprocket signal on PIN1
2. Send the data (Pins2-9) and wait
3. Raise the sprocket signal and wait.
4. Repeat.
I am looking for a method to control the data on LPT1 pins 2-9 and then be able to toggle PIN1 - Strobe signal - without the data falling from the other pins. What I have found is that whenever the state is changed on the strobe - the data that was written to Pin2-9 falls to zero. This will not work for my application - the strobe tells the hardware device that the data is ready. If it falls to zero when I toggle the strobe - that will not work.
Regards,
Guy

Hello Adam,
I am familiar with both references. If you look more closely at the library reference - it allows me to communicate using VISA across the parallel port pins 2-9. It does not permit direct communication to pin1 (the strobe signal) - property nodes don't allow the strobe to be refereced either (similar to control lines/signals for COM ports).
Worse, I have also located examples using OUT PORT that does enable pin1 to be toggled. The problem is, when those VIs are used, the data falls from the data pins when the strobe signal is written, even if its value is not changed. For example, if the strobe is already high, if another high value is passed, the data falls from the data lines. The other issue, when using VISA, as soon as the data is writen, the strobe signal automatically goes high even though I need a wait before setting the strobe high. This is in complete contradiction to the second article you referenced which clearly discusses writing data to pins2-9 then taking the strobe high to indicate to the printer that new data is available. It must be possible since this is the typical handshake.
I am still looking for a more complete answer/solution.
Regards,
Guy

Parallel Ports vs. Trashing Printers

Recently bought 3 new workstations: 2 w/Windows 7 - - 1 w/Windows XP Pro... Question is: my old HP Laserjet 2100tn will not work with these computers due to their not being a paralel port on the back of the computer.
Do they make converters for the cables to make them work? Or is the printer basically worthless at this point?
This question was solved.
View Solution.

You can purchase and install parallel port adapter cards and the printer will work. I can't specify which cards as you haven't stated what the specs are on your workstations. There are also usb to parallel port converter cables available.

How can I write to the parallel port using LabVIEW 6.0.2

I have tried updating the labview.ini file and also using the parallel.llb available on the site. When I execute the program it gives me error 37 saying,"device not found". I am running this code on windows 98. I tried to use VISA write,serial port write (using port 10) but nothing seems to work. I also tried to develop a sample code using inPort and outPort, but no success, it is not able to read the data back from the parallel port, even if it seems (????i don't know any way to cross-check it though????) to write.
Does anybody know the problem here?
THanks.
Pari.

Thanks Brian.
Well here is the next problem. I got a VI (attatched) off ni.com and it works fine on a windows98 platform. But quits working on NT.
I can write perfectly (which i checked by hooking an LED display unit at the other end of the parallel port cable). I observed that the LEDs respond to the toggling of individual bits (data bits). But the error occures at the "out port.vi", when I try to run it on a NT machine (where I actually wanna use it). Are you aware of any changes to be made in order to run a VI on NT that works on 98?
Thanks again.

How to Install a parallel port printer to usb port of Pavilion dv5 Notebook

In trying to install my HP DeskJet 610C Parallel Port printer to my HP Pavilion dv5-1235dx Notebook PC with Windows Vista Home Premium 64-bit, I followed instructions given by HP Support some two years back.
I connected up the two units through a Parallel-to-USB ports cable. The PC loaded and confirmed suitable driver. (Following advice from sites on the Internet, I have made repeated attempts to carefully install the printer, but to no avail).
Upon my issuing the Print instruction, the printer invariably prints two copies of what appears to be 'gibberish' in two lines at the start of the sheet. Thereafter it picks up and then ejects 6-8 sheets of blank paper.
Any help in resolving this anomalous situation will be be most welcome and much appreciated.
I might add that the printer works normally when connected in parallel to an older, Compaq Armada 1750 Notebook (XP OS). In this instance too, the Parrallel/USB worked as in the Pavilion PC, above.
This question was solved.

Using XP software with a parallel port dongle in windows 7 professional

Please help... Looking to have my parallel port dongle recognized for my older version software (XP) in Windows 7 under the XP PC mode. Help in figuring out if LPT1 is set correctly or what I am doing wrong.
Thanks

Hello,
I have W7 Professional 64 bit with Windows Virtual PC/Windows XP Mode installed. I have some older programs installed in XP Mode and they are working properly.
Unfortunately, I have one older program that I currently have working on an older XP Machine and that program requires a Sentinel dongle to be seen on the LPT1 Parallel Port. Since my W7 computer has an LPT1 Header on the mother board, I have purchased and
installed a PCI-Express Parallel Port and I have the ribbon cable connected to the LPT1 Header.
After I enabled the parallel port in the bios, I could see LPT1 in the W7 Device Manager and in the Windows XP Mode Device Manager. However, when I click on
Windows Virtual PC, highlight Windows XP Mode.vmcx and click on Settings, LPT1 does not appear.
I have installed my old program in Windows XP Mode and it starts to run but, when it gets to the point where it must see the Sentinel dongle on the LPT1, the
program does not find the dongle.
I also purchased a Manhattan MHUSB to DB25 Parallel Converter and plugged it in. It said that it found new hardware and installed drivers for it but that didn’t
work either.
I am not married to any particular solution. So, I would use a USB Adapter or LPT1 connected to the mother board but there must be some code editing or changes
in settings to make the dongle work in XP Mode.
Can you tell me how to get W7 Professional 64 bit with Windows Virtual PC/Windows XP Mode to find the Sentinel dongle
on LPT1?
Thank you,
Dan

Problem in sending data to parallel port

Hello,
I can open a parallel port (LPT1) using java comm api i,e javax.comm.
but problem in sending data to parallel port,
I choose the appropriate port(LPT1), it is in bi-directional mode according to BIOS configuration.
but according to the java program the mode is SSP.
when i write data to parallel port the volt-meter give a reading of high state for all data pin (pin1 to 9) i,e the parallel port doesnot change state. I am using windows XP.
What is the solution?

try it on Open Solaris 10 or Linux platform.
also just try using the new FileWriter("LPT1").write("Hello");
on windows platform

Sending trigger through parallel port, C++, Visual Studio 2010, Windows 7

Data Lines to be used as inputsSome parallel ports can be configured to use the data lines as inputs. It depends a great deal on the way the manufacturer designed the parallel port. With some models the data lines can be read the same way we read the control lines, by driving them to high logic so they will take on the value of an external signal. However, most parallel ports require that you set the direction bit for input. This is bit 5 in the Control register (base+2). If the port is capable of it, setting the direction bit high has the effect of making the lines tri-state so it can be driven externally. Sometimes it is also necessary to toggle bit 6 high or low. However, it should be noted that some manufacturers actually lock these bits so that software cannot change them. An example is shown below in Figure 7.
To test whether your data lines can be used for input, try the following:
Set bit 5 of the control register high (at base address+2).
With nothing connected to the port, write a couple of values to the data port, and read each back after you write it.
If the reads DON'T match the writes, your port is probably bidirectional. Setting C5 disabled the data outputs and you're reading the open inputs of the data-port buffer. If the reads DO match the writes, your port isn't bidirectional. The data outputs are still enabled, you're reading back what you wrote, and you won't be able to read external signals. If it is possible to use your data lines for input, then you just need to set control register bit 5 high and read from the value of the data lines at the base address.
