I have a small thermometer with a mini-usb connection. I would like to connect it via USB adapters to the 30pin connector on my iPhone. I am a paid dev ($99 version) and can't find much info on the hardware stuff. Is it possible to access this hardware with my current setup? I just want to access the data being generated via the temp...
I have what I hope is a simple question pertaining to the Atmel AVR microcontrollers. So I want to use the ATTiny85's Analog Comparator to determine if a signal is above or below a threshold. This signal is normally "floating" and pulled toward ground when "active" (i.e. it's an active low - open collector signal). If I enable the pullup...
I'm good at programming yet I feel like I don't know enough about the architecture of the hardware I'm working on. What does the Northbridge on the mainboard do? What does the L2 cache of my processor do? Can Windows XP use multiple processors? Not in terms of concrete multitasking in all programs but using the capacity of all cores if...
Hello, In our project, we've received a requirement where the the user is to be capable of enabling/disabling a COM Port / USB Port / Ethernet Port via our application's gui. Is it possible to manipulate harware's enabled/disabled state programatically in C#? ...
I am new to the locating hardware side of embedded programming and so after being completely overwhelmed with all the choices out there (pc104, custom boards, a zillion option for each board, volume discounts, devel kits, ahhh!!) I am asking here for some direction. Basically, I must find a new motherboard and (most likely) re-implement...
How can I get the name of the soundcard and maybe a few infos about it when using C#? ...
I somehow have the feeling that modern systems, including runtime libraries, this exception handler and that built-in debugger build up more and more layers between my (C++) programs and the CPU/rest of the hardware. I'm thinking of something like this: 1 + 2 >> OS top layer >> Runtime library/helper/error handler >> a hell lot of DLL ...

i have the memory address of certain register(the address LCDCW1 is C000). c codes: #define LCDCW1 0xC000 *LCDCW1=0x31; i just want to write data to this register. The codes have problems, how to correct it? thx! ...
Prototype working ternary device Quantum computing with qbits and so on is one thing, but what exactly do we stand to gain from a CPU which works on a ternary basis, where each 'bit' is ether yes/no/maybe (or true/false/filenotfound)? Is it simply an academic exercise or could it change processor design? ...
Hi: Is there a good way to benchmark a Visual Studio developer PC, instead of looking at the technical specs? Objective is to set a level and see every developer passes, if not upgrade them to new PC. Any thoughts and suggestions? ...
Could someone help me clarify the following conecpts, and the relationship among them?

I'm writing the audio part of a game, and I'm using OpenAL. I want to use some extensions, but the tests always fail: TRACE: AudioManager - Sound device: 'Generic Software' TRACE: AudioManager - Enabling OpenAL extensions... TRACE: AudioManager - Compressor support: NO TRACE: AudioManager - Reverb support: YES TRACE: AudioManager - Chor...
I have a WinForms .Net HMI software which talks to hardware over USB. I check for communication with the hardware at Load time and if communication is active then run it (The hardware manufacturer has provided a communication library to talk over USB). I want to build an emulator for cases when communication with hardware is not possib...
Suppose I have two memory segments (equal size each, approximately 1kb in size) , one is read-only (after initialization), and other is read/write. what is the best layout in memory for such segments in terms of memory performance? one allocation, contiguous segments or two allocations (in general not contiguous). my primary architect...
Hi guys, i have installed TFS 2010 in a 2 server setup with an App Tier server and a SQL Server and am not 100% happy with the performance. Both are running in VM's on SAN disks and have been given the following virtual hardware each: Windows 2008 R2 1 CPU @ 2.8Ghz 2gb RAM what should i lift - neither machine is hammered but both d...
How can I do division by 2 in Binary Signed digit (Redundant Binary representation) ? Shifting won't work right ? ...
How can I compare two numbers in the form of Redundant binary representation RBR ? Any Idea ? ...
I know that serial ports work by sending a single stream of bits in serial. I can write programs to send and receive data from that one pin. However, there are a lot more other pins on the serial port connection that normal aren't used but from documentation all seem to have some sort of function for signalling as opposed to data transf...
