i will explain the problem and the solution :
i wrote a code just to take an analog i/p and convert it to digital then send it to portc
and the output could be seen on leds connected to portc
the could is easy and has no errors :
.include "m16def.inc"
.def temp = r16
.org $000
rjmp start
start:
cli
ldi temp,$5f
out spl,temp
ldi temp,$04
out sph,temp
ser temp
out ddrc , temp
clr temp
out ddra , temp
rcall adc_initial
sei
Main_loop:
in temp , adch ;read adc high
out portc , temp
rjmp Main_loop
adc_initial:
sbi acsr , acd
ldi temp , $60 ;single i/p (ADC0)
out admux , temp ; *1 gain - left adjust result
;ref = Vcc
ldi temp , $a6 ;adc enable - auto trigger
out adcsra , temp ;/64 prescaling - no interrupt
ldi temp , $00 ;free running mode - no pull up
out sfior , temp
sbi adcsra , adsc ;start conv
ret
when i simulated the program on proteus it doesn't work at first , because i used to connect the AVR without connecting the Vcc pin and it was working so in all programs with no problems , but in this code you have to connect the Vcc pin

Sounds like a really detailed simulator. I'd think if external power was being applied would be overkill. Out of curiosity what happens in the simulator if you connect VCC to 50VDC or 120VAC instead of the 5(3.3?)VDC the chip being simulated is expecting. Does it error out with "Magic smoke released!"?

Initially it runs faster, and then it blows up. What did you expect?

I sh*t you not; I’ve never asked a question neither here nor in MSDN or other programing forums.
Here is my problem – my Alienware suddenly lost the monitor drivers and set them to some basic monitor with no 1920x1200 resolution option. I removed the driver, restarted the thing and it still insists that I have some old CRT monitor instead of 22’’ Dell widescreen. I’m out of ideas how to fix this without a system restore. The OS is Weven and my best guesses what causing this mess are:
0. I’m not using a DVI cable, so this could confuses the OS.
1. MS Security Essentials cleaned a couple of nasty viruses two weeks ago, so they could have left some crap behind.
Any ideas beyond the obvious “format-reinstall” routine?

Try Microsoft Update to see if it updates your drivers (you will have to choose the custom option so you can select hardware updates).
If that doesn't work, go find the drivers and install them manually.
If that doesn't work, find the drivers for your video card and install them manually too.

Maybe. Above a certain resolution, VGA looks crappy. Not sure if you are actually prevented from doing so though.

Already tried to update VGA and Monitor drivers from the device manager – regarding Windows there are no new versions.

This sound reasonable, I’m gonna try it today after work, thanks.

It used to work for me, at least until now.

Yes please, and while you are at it you might want to give back your degree certificate to the university

I would try, but they won’t let me to step back in the uni. I have a 10 kilometers restriction order from the campus.

Do you have the "Works on my machine[^]" certification?
(Also: do you mind if I move this thread to the Hardware forum?)

I've had this happen to a machine only after a Windows Update. Have you installed any lately? If so, you might try rolling back to a Restore point before the change to see if that helps.

You need to reinstall the video card drivers I would say.

Silly question:
At home I have two PC's both with Gigabit NICs, plus an Epson BX310FN network printer and a Media Player (definitely 10/100MHz).
Currently, I use a Netgear DG834G modem router.
I have just bought a Gigabit NAS and am wondering if it is worth upgrading the router and cables to CAT6/gigabit. Will the printer work at Gigabit if I do upgrade? Will it slow everything else down? The tech specs don't appear to list the network speed it copes with and I am not sure if you can mix Gigabit and 100Mhz on the same router.
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

No, the speed of tx/rx is determined by the LAN HW on the device.

No.

I didn't think it would, but I am reluctant to replace working cabling, router, etc. if I wasn't sure. If it ain't broke, don't fix it certainly applies to cables-in-walls (even if they are in trunking). Unless you are going to get some real benefit and the wife won't notice until it is all working again of course...
So let's have a look for a five+ port gigabit ADSL router with wireless and CAT6 cables...
Thanks!

I thought it used to be that some budget hardware fell back to the speed of hte slowest attached device. Am I misremembering or has that limitation been removed from even the cheapest networking gear today?

You could have a point. My LAN knowledge is more theoretical (kernel side) than practical so if some cheap products mess up the protocol then it might happen.

*nod*
however, now that I'm more awake I think the problem might've been limited to hubs which AFAIK had to send an identical data stream to every attached port.

I think it has. Most of it anyway. Most switches and NICs these days transmit at the maximum rate supported along all points of the signal path. This means that if you had two 1G NICs connected they would use 1G. If they went through a 100M switch then they would use 100M.

Hi,
I'm using Windows 7 Ultimate (64 bit).
I have a new USB hub that is causing some problems.
If the PC boots up with the hub attached then the hub isn't recognized and some of the built in ports don't work (these ports have an external hard drive and a wireless network adapter plugged in). Some of the built in ports do work (these ports have the mouse and keyboard plugged in).
If the PC boots up without the hub attached then all of the built in ports work fine. If I then plug in the hub all the devices plugged into it work fine.
Any ideas what I can do to make the PC boot up and have all built in ports and all ports on the hub work correctly?
Thanks,
dlarkin77

Out of interest what are the error codes in device manager fo rthe failing hubs?
Do you know if the hub causes the same behaviour on XP?
Can you identify the driver associated with the hub? If so you could force it to start later, set its start type to 3 in the services\<driver name=""> key.
If you dont need USB boot capabilities then you could try moving it down the list in the BIOS, this might help.
Generlaly though this kind of thing is fairly typical of USB on post XP oses. Microsoft really messed around with the USB subsys on Vista, it caused a hell of a lot of problems which got carried over into 7. Previously working HW would fail, behave erratically, all sorts of stuff.

Your suggestion led me to this [^] hotfix that seems to have sorted my problem.
Thanks for the help.
