Please, this is the Hardware forum, for a C# question, post in the C# forum.
Thank you.

But using C#. You might get some help here, but I think you would be better off in the C# forum. This forum is more for discussing hardware and hardware problems, not how to use them in programming.

google
I found 2 tutorials, 4 books, one resume (of a guy who does this), a class at a university, a trade-school. The great and powerful Google knows all, providing you put in the right phrase, partial phrase, or key words.

u should think how plc interfacing with computer, serial/parallel then deal with this aspect using any programming language.

ı have got a project.I want to circuit diagram and assembly code of controling motor.but i must to use ULN2003a chip on the circuit;
TOPIC=Multiple-Peed Stepper Motor Control and Digital Display
(To be submitted by 5 January 2006)
The term project is about writing an Assembly Language Program to control a Stepper Motor interfaced to a PC through the parallel port. The project contains the following 3 main modules:
1. Stepper Motor Driving Module (Output Module):
· The motor will rotate clockwise if f (forward) key is pressed and will rotate anticlockwise if r (reverse) key is pressed from the keyboard.
· The speed of the motor will be controlled by the external push buttons (Up and Down) connected to the PC through the parallel port. If Up button is pressed the speed will be incremented by 1 out of 10 speeds. Down button will work similarly.
2. Speed Display Module (Output Module):
· The speed of rotating motor will be indicated by displaying a single digit 7-segment display. There will be speeds from 0 to 9. The speed which is displayed on the 7-segment display will also be displayed on the monitor with its direction (clockwise or anticlockwise)
3. Up and Down Push Buttons (Input Module):
· The speed of the motor will be controlled by the two external push buttons. The speed will be incremented or decremented one by one by pushing to Up or Down buttons respectively.

Are you going to build the circuit? What class are you in? Its a very interesting project but I don't think the people here are going to supply you with a complete schematic and a program written in assembler for no price. There are some programs written in C# that control motors through the parralel port, maybe here or programmersheaven.com

First, how long have you been sitting on this project, not doing anything?
Now you're down to 3 weeks and haven't got a clue how to do this? You may as well just go on vacation for 3 weeks because you're gonna fail.
Noone is going to just give you a schematic and code to save your butt. You're going to have to do the research yourself to build and test the circuit, as well as writing the code for it. BTW, hardly anyone uses Assembler anymore, especially under Windows, so good luck trying to find an example of that.
Can you tell I hate procrastinators who just think they'll find the complete finished answer to their homework assignment, final paper, or whatever, somewhere out on the Internet, just waiting for them to ask for it and someone to hand it over?

Hi dear
Im not an expert on such stuff but i have done lot of hardware programming using assembly
If i would have to do such a project i will do it like follows:
1. Know All the protocols for parallel port IO
2. Kow the way that chip behaves, i mean the interface exposed by that chip
3. Use some good assembler to code the modules
4. Use a GUI interface to control the modules
Hope this may have given u some idea.
Would u like to send me the chip specification and OS u are goin to use
bye

Hi
Can i use 32 bit assembly to get my CPU ID(Not whether it is 16 bit or 32 bit).
How can I tally whether it is the same one that i purchased(i mean ID of box).
And is there a unique id for every Intel processor.
Bye

I have an Intel Processor chip and I am looking for a way to tell what 'kind' of chip it is.
I THINK it is a P4 2.8 Ghz celeron. I know it is a celeron because that is plainly written on it.
The only other ID markings on it are as follows:
633/128/66/1.65V

Any ideas?

Just got to the System Information and select System Summary. Your processor information will be there.

Forgot to mention that this is just a chip and I don't have it in a mobo yet.
I want to get a mobo for it but I am not sure of the chip so I am unsure as to what mobo to buy.
|
|
|
|
|
It should say on the top of the chip, if not, you could try looking at the package that it came in. Otherwise, I'm not sure.

I believe that's a Socket 370 chip...

Hi everyone,
just how much is the difference between the GeForce 7300GT and the GeForce 7600GT
in terms of performance? (FPS, 3dMark, F.E.A.R, FarCry)?
Can someone please guide me on this?
I really need to understand how these two compare.
Please help.

Hi~!!
I'am Korean. Not Use English. So I can't English well.
I have problem. like subject.
i need to setting Mixer.(MFC Programing)
but i don't know how setting Front Mic in coding.
each computer are different. one thing in inline-list, otherwise anoter in mic-volume.
so it is hard to solve. my word is diffent to setting Front-Mic.
Help me. please.

Hi,
I'm planning to build a high-end PC within a decent budget.
(At least I hope to)
I want to know whether the single core Intel 3.2 GHz CPU
or the dual core Athlon 3600+ will offer better performance?
(Let's say I have to choose between these two).
Also, is the single core 3.2 GHz Intel CPU 64 bit? I know the
Athlon 3600+ dual core is 64bit. Does having 64bit mean better
performance?
I plan to run very cpu intensive applications like Audio Workstations
and 3d Graphics software.
Basically, this is going to be a multimedia production and video
editing system.
Also, please tell me to what extent can the motherboard affect
the performance. Is is really a performance factor? Or will a
decent motherboard do?
Please let me know quickly as I have to make the decision within
a few hours.
Thanks.

Hi,
I would recommend you to go for a dual core processors if you are planning to use your PC for multimedia purposes.
Better Performace in 64 bit machines can be obtained by running 64 bit version of the software you are planning to use.
Motherboard too plays a vital role in obtaining better performance.The interface through which it communicates with the processor ie FSB (front side bus) should be high. make sure your motherboard supports FSB frequency offered by the CPU (you can locate the FSB frequency on the processor box) that you choose.

any one know how 2 hack into another user profile while your account is a limited account and their account is a administrator's account?

You don't. If you don't have rights to the other profile, you're not going to them.
Boot the machine on something like ERD Commander (Google for it...) and you'll get all the access you want to everything.
