People are unlikely to download and unpack some packed file just to help out. Paste the relevant code (inside PRE tags!) if you think it's useful. Also explain "doesn't work", it is not informative at all.

then you could add the solution so others might benefit.

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 Smile | :)

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!"?

My first question in programing forum

30-Aug-10 10:27

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. Unsure | :~

(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.

Mixing 100MHz and Gigabit

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.
