An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. Examples of properties typical of embedded computers when compared with general-purpose ones are low power consumption, small size, rugged operating ranges, and low per-unit cost. Modern embedded systems are often based on microcontrollers; the processor(s) used may be types ranging from general purpose to those specialised in certain class of computations, or even custom designed for the application at hand. A common standard class of dedicated processors is the digital signal processor (DSP).

Hello EE,

I have a job for a client and he is asking if there is a way to push content from a laptop to a projector and TV via a wireless connection in his office. The only way that I can thing of is to connect the Laptop to the Projector and display on wall. He was to use a 60 LCD TV and push content from his Laptop to his TV which has a cat5 connection only and no wireless connection builit in TV.

I am rebuilding a degraded RAID array 0 that's 189.GB and its been stuck on 42% for over three hours. Should I be concerned? Should I let it run overnight? Do I power it down and restart?

hi/
i have a tiny lab timer, it counts from 0 to 9. but i want to stop on it when i provide a value to one of it is input..

i want the stop save the vaue too in a microcontroller's memory.
i want the stop hold the value on my seven segment (show when i have pressed the stop button)

can anyone please read throu my code and let me know;
          1- where i can place the code
          2- how can i set the right pin as input on the microcontroller



please note that i am using MCC18 compiler with C programming, and usong MPLAB IDE v8.33

thank you

Hi experts,

I purchased a computer which came with a motherboard that has an onboard analog video jack. It also contains an nVidia Quadro NVS 295 Connection.

When I connected the computer to the monitor using the analog cable, I could not see the monitor at all. I tried it on three working monitors. I then noticed the other connection. I am not sure if the onboard is defective or if it is turned off in the BIOS, but I can't get into the BIOS to change it.

The monitor has an analog, digitial and another connection I am not familiar with that may be an HDMI. It is rectangular with a slight slant at one end.

The NVS 295 card has two female connections for two monitors both of which look similar to the connection on the monitor. I have no idea how to use these connections to connect to the monitor. I reaad the manual on nVidia's site, and it wasn't very helpful and didn't mention HDMI.

I do have a brand new right out of the box video card from nVidia that I could use, which seems like overkill.

Any help would be appreciated.

I need a single chip bluetooth solution that supports the bluetooth HID profile. I've come up with one (BCM2040) but that only comes in a BGA package and i can't find a place to buy a single chip. please help me find a similar chip, preferrably in a diferent package.

I need one for my computer technology project (motion controlled mouse + video game controller) and i don't have the necessary resources for BGA soldering. i need to be able to buy this online, just one chip. thanks.

Hello Experts!

My Dell D-610 locked up on me last night and had to force a reboot.  I can bring it back up in safe mode but on a normal boot, the OS loads...the Win 7, (Ultimate), logo appears and pulsates as usual...then I hear scratchy sounds coming from the speakers.  The screen goes dark and the hard drive indicator light quits flickering.  The fan stays on, but it seems like the hard drive quits functioning.  Again, can boot to safe mode just fine.

I have a spare D-610, so I swapped the hard drives.  The same thing happens with the hard drive from the spare, now installed in my 610.  The OS, (XPP 32 in this case), loads...the desktop comes up...the scratchy noise comes from the speakers and the hard drive seems to stop.  The hard drive from my 610, (now swapped to the spare 610), boots into Win 7 fine except for the video card needing a driver which would be expected.

I'm thinking hardware issue because the Wind 7 drive works in the spare 610...so it couldn't be a OS or driver issue...or could it?  If it is a hardware issue, what hardware?  I tried disabling the sound card in the BIOS, but there is no option to do that.  Tried disabling the video in the BIOS and that didn't work.  Reset BIOS to default...problem still there.

Any ideas...besides replacing a 5 year old laptop?  :-)  Have not yet tried an OS repair from the Win 7 disk...but I don't think it is an OS\driver issue.

THANKS!
Mick

Hi,

I am an absolute beginner and should program Ripple Carry Adders on FPGA with NIOS II.

If I had the code for programming a 2-bit ripple carry adder, I would extend it to my needs.

Can somebody help me with a link or directly with the code?

Many thanks in advance

Have a nice weekend

I am going to set the Cache Write Policy to Write Through from Write Back on a Virtual Disk.  I believe this would be done through the hardware RAID controller utility during the POST cycle.  Is there any preparation necessary or will there be any additional steps I will have to take after changing this?  These are DC's I am changing this on and I don't want the servers to blow up after the fact.

I have a HP Slimline s3123w pc and when i try to boot the pc it gives me a beep code of 2 short and 1 long. I looked up the beep code and it says "unable to initialize video" I was going to order a video card for it, but normal sized ones won't fit in the slimline. the bracket is too long. Which one and where would be the best place to get one for this pc?

I'm doing a case switch for a friend, but the USB cable from the front panel is wired differently than the motherboard's USB header pins. I cannot find any information on this board to find out what the exact layout of the pins are to change the harness. The board is labeled as an Intel E210882. I can run Everest to get the exact model...I've heard that this marking of E210882 is common on different boards.

Anyway, The USB cable has a jack with a 10 pin layout. There are 4 wires on each side of the adapter, Red, White, Green, and Black...two of each color. I'm assuming one group of these wires (R,W,G,B) correspond to one USB ports on the front panel.

The original layout of the adapter was White, Red, Green, Black, Empty...on each side. With this setup, the machine would completely freeze when any USB device was attached. The only diagram that I found online showed a setup of Black, Green, Red, White. I took a chance and rewired the harness. Now, when I plug in a device, nothing happens. My device has a blue LED to indicate power...but it does not light up.

I don't really want to take another chance and was hoping that someone out there has an idea of the correct pin config for this board. I'll run Everest and post any more findings!

Thanks in advance for your help!

I have a Compaq SR1954NX that has an AMD 3700+ cpu and an ASUS A8N-LA motherboard. Recently I had to reload Windows Media Center 2005 on this computer, however after downloading all drivers from Compaq I still have one Unknown listed in device mgr. Everest has id the device as PNP device Intel Quick Resume Technology, but I have been unable to locate any drivers that work for this OS / mobo combo.

Hey guys,

So what do you think about the digital memory vs.  movable hard drive parts.  Looks like the thumb memory getting bigger and bigger.  Will it replace the hard disk at some point when the size will be large enough?  Or is there some more bumps besides the capacity?

You can find USB flash drives as large as 256GB now and weigh as much as 30g.

What's your opinion?
Thanks!

Does Latitude D630 has a built-in camera?  I see here is a small square window on the left screen side.

However, I do not see it in Devices nor Control Panel ->Scanners and Cameras.  Is it fake for optional custom install?  

Also, does it have a built-in microphone?

Thanks in advance!

Hello everyone,

I am just about ready to take my computer back to Best Buy and tell them I want them to replace the hard drive. I took it to them once and it came back with two "new" hard drives and a technician's signed statement that all was functioning well. The problematic hard drive has the following specs:  

The computer is almost three years old.
It has two hard drives.
The problematic HD is a TOSHIBA MK1252GSX (111 GB)
Partition Type: NTFS:

Here are my system specs:
Computer: HP Pavillion 9628nr
ACPI x86-based PC
OS Service Pack: Trial Version (I don't know what that means. I purchased the OS)
Windows 7 Home Premium (an upgrade from Vista Home Premium)
3 GB RAM
Motherboard Chipset nVIDIA nForce 7150m-630m, AMD Hammer

Here is what the HD is doing.

It works fine normally, but ever so often, It decides to disappear. If there is currently a program trying to access it, I get the message, "Path cannot be found." It disappears from the Windows Explorer. When I run Device Manager, it has disappeared from there too. The only way to get it back is to reboot the system and sometimes I have to do that 3 or four times before it reappears.

Here is what I have done so far:

1. I ran the SeaTools for Windows diagnostic tool. the HD passed ALL the tests!
2. Ran a check disk with "scan for and attempt to recover bad sectors" selected. It found no problems.
3. Copied all the data off the disk and reformatted it
4. I reformatted the disk using the slow …

Hello, I will be installing Small business Server 2003 on an HP Proliant DL380 G4 that were donated. There are actually 2 identical boxes with 5 36GB SCSI drives in each. Should I install everything on one server? Or is there a way to split up exchange on a seperate box etc? If so, would I have to install an OS on the 2nd server to lay Exchange on top of? Also, are their any resources out there you could suggest with installation tips etc? This will be my first time actually installing it. They have a fractional T for internet, and a wireless router...

Also, I would like to build in some redundancy, Raid 0 for each box?

Thank you...

I have a Windows program written in C# that I've ported to Mono on Linux.  It uses serial communication to a CP210x Serial to USB device (/dev/ttyUSB0).  It works fine on Windows at 128000, 127117, and 125000 baud rates, but fails at 115200.  However, when I run it on Linux, Linux will only accept 115200 as the closest value to the above and the data is corrupt.

I need a solution that I can use in C# or the command line.  A C based solution would be workable as a separate executable, but I don't really know how  to write it so would need a lot of details there.  This needs to work on openSUSE, RHEL5, and Debian.

My question is this, how do I change the /dev/ttyUSB0 baud rate on Linux to one of the higher values mentioned above?
