What would interfere or cause an interupt? Windows xp pro, usb to serial with prolific 1.8 drivers (I think... sorry tried three diff versions thus far), legacy hardware enabled, power disabled on usb root, serial mouse detection turned off (uses usb mouse anyway and PS2 connected keyboard). 232 data converter to usb to serial and the application is based on .Net 2.0 / Visual Fox Pro (not my app). Besides the monitor, no other connected devices for i/o. Has all updates.
Everything seems to test fine. (Telnet to 232 works as well) I am at my end of knowledge or just missing the obvious.
Suggestions? It works about an hour'ish and then just stops.

I did not catch anything of significance. I did find that I would get a contious receive. I think the dc is bad.
However, with all of this I did switch machines (so to speak ... hit the junk pile and built one from pieces and parts) and had the same problem. After some time, I had a light-bulb go off inside my head. Update the chip set drivers. It worked.
Stupid me. I should have considered drivers on the previous machine. It just never even crossed my mind that they could have updated or needed to update with a Win Update. Ouch ... such a newbie mistake.

Hi to all,
Is there an official way to propose a new chapter and forum section? Or is it enough to say that I want a new chapter for Arduino articles? Or may I want it in this forum

Such as a USB keyboard to press a key, an interrupt is generated.
thanks muuuuuch

I'm not sure about how to simulate one, but I remember using the standard PC keyboard interrupt to trigger events in a C++ (state machine) program assignment I wrote. My lecturer just loaded it onto his PC with all his work on it to try it out and it worked and importantly then returned normal function to the keyboard interrupt I'd used - Interrupt 9. I used a book 'The undocumented PC for information which is/was very good for this sort of stuff.
As you mention a USB device, try looking at devices that provide Inputs and Outputs - they often have one or more inputs that can be set to trigger an interrupt when their input state is changed - by say a switch. I've used mostly internal PC I/O cards which can trigger interrupts but also USB devices which provide the same functionality. Serial Port connected devices also have/had this functionality - even if your PC may no longer have a 9 pin serial port.

Hi everyone
I'm developing an application in vxworks. In this application I use uart in polling mode for reading and writing.
The problem is that when I disable uart interrupt using "intDisable" command, uart generally does not work in polling mode.
The question is whether this is normal? Why uart does not work in polling mode if I disable it's interrupts.
Thanks for the tips of your

Hi A_Fa Can I know which CPU you are using?

Excuse me for very long delay in response.
Our target board is ML507 with PPC440 processor.
Thanks very much.

Up front, I apologize if this is not exactly code related , but I am stuck.
I am trying to resurrect my Win7 from image.
From Win7 setup disk I select “restore from last image / backup”.
The restore app identifies the internal SATA drive and lets me select it for restoration.
So it knows the drive exists. The resoration process suppose to format the drive, it does not.
and the restoration fails and the only option is to “download HD driver”.
My XP PC does not use SATA so I cannot let helpful folks scan my PC for this particular drive.
I have been unable to find JUST the driver, but I keep looking.
The catch is – Win 7 opens \System32 when I try to find the suitable driver.
So my basic questions -
if the restore apps knows the type of the drive , where in the \System32 is the driver located?
If it is there why can the restore app find it for me?
Is there any other way to restore the image to the internal drive ON DEAD PC?
And reasonable suggestions would be appreciated.
Cheers Vaclav
PS I have not found answers Googling.

Your post is a bit of a cluster... between talking about XP and Win7, SATA and not having SATA, I have no clue what system you have and are trying to rescue.

Try installing windows 7 first and then restore the image with a running windows not from the setup disk.

I'm trying to head off an IT inflicted disaster. IT wants to move the s/w team I am on to a new machine. They desperately need to do this, and I'm not arguing. However, the LAST time they moved a lot of our files (backup development zip files for example), the transfer (xcopy) corrupted them. It wasn't until a year later when I needed the old code the problem was discovered.
So, alternatives to xcopy? I'm sure there must be something better out there that will do a binary check for a good copy...
Anything else I should fear?
Thanks

Yeah, *that* will work. I own my own consulting firm, but I am on contract. So....
But, I can certainly insist politely. I see the backup/restore has verification, so that's better.
That reminds me, I need to image my hard drive....

There is a new copy program in Windows called Robocopy[^]. It might work better for you.
The difficult we do right away...
...the impossible takes slightly longer.

... which is in fact what IT eventually used, but thanks
Interestingly, the first time they ran it with a full check after the copy, it failed with some obscure errors due to corporate networking rules. Hamsters ran for 16 hours and then failed. The next weekend they tried again - good move, fully verified.

Hello
Can anyone Know how I Create Printer Driver and use it from c#.
thanks.
|

Yes, anyone can learn how to create a printer driver.
If you want to know how, it would take an entire book to describe. That's not something you're going to learn from a couple of forum posts. You've been told where to start, and, yes, there are books out there that will teach you how to create drivers.

Thanks for answer
I am now on the msdn website and I am looking for it but I get confused if there any book give it to me
thanks...

Seriously? You do know that Amazon has a search function, right? Try "Windows Driver Development".
