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).

hi
please can you help me
for sim808
i used it to send longitude and latitude for ulr (https),
but on arduino's serial monitor appears that
AT+CGPSINF=0
and the value of latitude and longitude =0
where is the wrong ?
is in the code or device
thanks in advanced

How can I reset an Intel S2600cp server system board to default settings using the jumper settings?

Currently, this board won't boot and I don't get any display (even after removing the battery).

What are the steps to reset this system board to its default settings?

Attached are the manual and tech specs for this server system board.

What is the meaning of 5 long followed by 3 short POST beep codes on an Intel S2600cp server system board?

There is also no monitor display.

A Lenovo Ideapad Yoga 910-13IKB laptop running Windows 10 Professional is unable to use the built-in camera.

When we run the Windows 10 camera application or try to use applications that use the camera (such as Skype for Business or Web Ex) the user's camera isn't recognized).

I have updated the drivers (including obtaining the drivers directly from the Lenovo.com webpage) and have checked the UEFI BIOS settings and the Device Manager and don't see anywhere where the camera is disabled.

What else can be done to fix this issue so the built-in camera will work?

I have an old dell r710 server with an embedded hardware RAID controller. This is to be a test box, it only has 1 1TB drive in it. I am unable to install an OS on this machine. I suspect that I must create a RAID which means I need another hard drive. Is this true? Also when I boot to system manager it states that no virtual disks have been configured

This course will introduce you to the interfaces and features of Microsoft Office 2010 Word, Excel, PowerPoint, Outlook, and Access. You will learn about the features that are shared between all products in the Office suite, as well as the new features that are product specific.

I have an Intel S2600CP server board in my lab that is currently running Windows Server 2012 R2.

I need to replace this server board with another Intel Server board that:

- Is fully compatible with Server 2016

- Will accept the two CPUs & RAM currently being used in the Intel S2600CP server board.

What are some Intel server boards that will be able to do this?

Please let me know if any further information is needed.

Attached is the manual and service manual for the Intel S2600CP server board.

Hi Experts,

I am a final year diploma student of Computer Engineering. Currently i and my team are looking for title for our final year project. We need your recommendation of our final year project. The topic is about network management, network security, embedded system, IoT, or cloud computing. Do you have any good idea?

If you don't mind, please share your ideas, suggestion, or experience.

Thanks in advance

EE,

I have a Dell Optiplex 980 SFF which was purchased from Amazon.  The  unit appears to be in good working order, EXCEPT for the "on-board" VGA port does not work - the unit came with a graphic card and now I know why.
> I removed the graphics card because it was running very hot and for this application that this workstation will be used, simple VGA will work just fine.
> Connecting to the on-board VGA port, there was not video during POST and after a time, I could hear Windows familiar chime when completing it's boot up.
> I started to troubleshoot.
> After having to deal with a dead CMOS Battery, I was able to configure the BIOS to use only the on-board Video (aka the VGA port) and after several attempts, the only way I can get Video at POST is with the graphics card.

So, I purchased a new(??) Optiplex 980 System Board (Which also had a dead CMOS battery, which I replaced with a new one) and low-and-behold, it TOO has a faulty VGA port.  So, now I have to ask myself...
> Am I doing something wrong?
> Is this a class issue with the Optiplex 980 SSF models?
> Was the second system Board a "used" one with the same problem?

So, I thought I would reach out to the nebulous and see if this is me or something else.

Inquiring minds need help....

Hi, we could not start the vmware physical host after rebooted. It stuck in the black screen. I also noticed that 1 of 2 SAN switch was on orange light. SAN storage is still okay. Can you please suggest?

I'm programming Infineon TC29x Aurix Tricore Microcontroller based embedded system in 'C' language.  

Consider stack starting address 0x5000 0000.  The stack size is 0x2000.  

If I take current stack pointer minus 0x2000, will that create stack exception?  If yes, what might be 'C' or assembly language code that will achieve this?

My thought is if I subtract negative 0x2000 from current stack pointer or add 0x2000 to current stack pointer, I'll be outside stack and stack exception will occur ?

 I need to set program counter to illegal address, i.e. 0x00FF FFFC.  Can this be done with assembly language instructions?
 If yes, please instrument assembly language instruction that would set program counter to 0x00FF FFFC while code is running.

We are using TC29x Microcontroller. The flash size is 6Mbytes. There are Three banks, 2Mbyte each.

Program Flash 0 (PF0) is bank 1. Program Flash 1 (PF1) is bank 2. Program Flash 2 (PF2) is bank 3.

 PF0 address range is: 0x8000 0000 - 0x801F FFFF
 PF1 address range is: 0x8020 0000 - 0x803F FFFF
 PF2 address range is: 0x8040 0000 - 0x805F FFFF

 Where is Program Flash ECC stored. Is it within 6Mbyte ? Or is there additional storage space for ECC that we don't have access to ?

 How does Flash ECC work ? For how many bytes of data, how many bytes of ECC are there ? Whenever we write to flash, ECC updates? When we erase flash ECC updates?

 How is it possible to create Flash ECC Error ? Because everytime you write or erase flash, ECC will update?

Consider a typical Automotive Embedded  Software System.  

A discrete input signal is 0 or 1.  An example of discrete input is ignition ON or OFF.

After discrete input signal is debounced or a state change is latched, is discrete input signal still raw value?

Second question:   Should Electronic Control Unit (ECU) low level software debounce discrete inputs or just read the real time state of discrete input?  Are there any exceptions meaning some discrete inputs should be debounced, whereas others don't need to be debounced?

In a typical embedded automotive embedded system, I believe data is only transferred from RAM to EEPROM once every key cycle, right before embedded system goes to sleep ?

I'm just getting started with a PIC32MX340F12, and MPLABX. My first attempt was to write a timer interrupt, so I worked with the datasheet, compiler manual, and examples and came up with the below. But it doesn't work... the interrupt never fires, and in fact if I leave both the timer interrupt enable (T1IE=1) and the general interrupt enable active ("ei"), it runs for a few seconds then hangs (says "target halted" in debug mode). If I remove either of those, it just runs indefinitely but still no timer interrupt. So I appear to have a pretty bad problem somewhere in my ISR syntax. Does it jump out at anyone?

Like I said I'm just getting started so I'm sure it's a pretty dumb oversight. And as you may notice I like to work as directly as possible with registers and compiler directives (rather than manufacturer supplied functions), I feel like I learn the most that way.

Thanks!

    T1CONbits.TCKPS = 1;  // set T1 prescaler to 8
    PR1 = 62499;          // set t1 period
    TMR1 = 0;             // initialize the timer
    T1CONbits.ON = 1;     // activate the timer

    IPC1bits.T1IP = 5;    // T1 priority to 5
    IPC1bits.T1IS = 0;    // T1 secondary priority to 
    IFS0bits.T1IF = 0;    // clear the T1 flag
