Logix4u SCSI Utility is a simple application that enumerates all SCSI devices (including SAS, SATA, ATAPI, iSCSI and USB storage devices) on the host machine and can send custom or predefined CDBs to any enumerated device. Many CDBs including Inquiry, Read Capacity, Log Sense, Request Sense are already defined the application and can be invoked by a single click. The custom CDB feature allows the user to build custom CDBs and send it to any device and see the results.

Contrary to popular legend, if you can write a Windows application in a
compiler based language ( C/C++, Visual Basic etc), you can also write
it in Assembly, especially if you choose a Macro Assembler such as MASM.
32-bit Assembler is Easy, why and how to develop using the assembler? Start learning to program in Assembly now!

Python is a simple and powerful language for scripting and even
application development. Various GUI packages available for Python
makes it suitable for developing full fledged applications in python.
Ok that is fine, but ever thought of creating an executable file from
the python script you wrote? This seems to be a nice idea, there are
many reasons why! You can redistribute your application without
python. The end user needn't to install python on his machine. You can
make your application closed source (unfortunate) etc... Read on this
article to find how you can create win32 executables from your Python
script.

Storage systems are inevitable for modern day computing. All known computing platforms ranging from handheld devices to large super computers use storage systems for storing data temporarily or permanently. Beginning from punch card which stores a few bytes of data, storage systems have reached to multi Terabytes of capacities in comparatively less space and power consumption. This tutorial is intended to give an introduction to storage systems and components to the reader.

In computer technology, BUS is an interconnect that helps data to be transferred between CPU and different peripherals or between computers. a BUS fascilitates an organized and usually co-operative access on resources. in contrast to point to point connections, a BUS can logically accomodate several peripherals irrespective of their type and functionality as long as it confirms to the rules specified by the BUS specificaton. While learning about storage domain, different types of BUS technologies and standards come in to picture. Let's take a closer look in to the different BUS standards used in storage technologies.

To write an interfacing program with
parallel port or serial port, we need to know the base address of the
corresponding port in advance. Normally the base address of LPT1 will
be 0x378 and that of LPT2 will be 0x3F8. And most of the home PCs will
have only one parallel port with base address 0x378.

Though discrete fourier transform can convert time domain data in to frequency domain accurately, it has an unavoidable drawback. It is the inefficiency of the algorithm which makes the processing much time consuming. As a solution to this problem, Fast Fourier Transform (FFT) is invented. FFT is much faster and efficient than DFT. the sample program written in Visual Basic lets you generate different waveforms, and examine its spectrum.

Fourier Transformation is used to transform data in time domain to frequency domain and vice versa. The forward fourier transform or simply fourier transform is used for time domain to frequency domain transformation. Where as Inverse fourier transform is used for reverse process. Here you can find a visual basic sample program implementing fourier transform using correlation method.

The windowed sinc filter uses the inverse fourier transform of ideal low - pass filter frequency response. The Inverse transform of the ideal low - pass response is the sinc function (sinx/x). The inverse fourier transform of the required frequency response is taken and used as kernel a normal filter.

Liquid crystal display is very important device
in embedded system. It offers high flexibility to user as he can display the
required data on it. But due to lack of proper approach to LCD interfacing many
of them fail. Many people consider LCD interfacing a complex job but according
to me LCD interfacing is very easy task, you just need to have a logical
approach. This page is to help the enthusiast who wants to interface LCD with
through understanding. Copy and Paste technique may not work when an embedded
system engineer wants to apply LCD interfacing in real world projects.
You will know about the booster rockets on space shuttle. Without these booster
rockets the space shuttle would not launch in geosynchronous orbit. Similarly
to understand LCD interfacing you need to have booster rockets attached! To get
it done right you must have general idea how to approach any given LCD.This
page will help you develop logical approach towards LCD interfacing.

A moving average filter averages a number of input samples and produce a single output sample. This averaging action removes the high frequency components present in the signal. Moving average filters are normally used as low pass filters. In recursive filtering algorithm, previous output samples also are taken for averaging.
