A Linux Device Driver for USB to USB Direct Link Device

The first version of the Universal Serial Bus (USB) specification was released in January 1996. In April 2000, version 2.0 of the USB specification, which supports transfer rates up to 480 Mbps, was released. Because of its low cost, high data-transfer rate, ease of use, and flexibility, USB has gained wide acceptance in the computer industry. Today, many peripherals and devices connect to computers through USB interfaces. Currently, most general-purpose operating systems pro ....etc

USB EXPLAINED: AN INTRODUCTION TO USB AND ITS FUTURE


USB HISTORY
The Universal Serial Bus (USB) was introduced to the world of PC computing to solve the growing problem of how
to connect peripherals to a PC. The world of desktop computers needed a way, not only to physically connect
devices, but also allow them to be identified and categorized to enable a simple ease of use and method of discovery.
Prior to USB, many people overloaded the use of their serial and parallel ports to supp ....etc

DIGITAL STORAGE OSCILLOSCOPE

What is an OSCILLOSCOPE ??
An oscilloscope (also known as a scope) is a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional graph of one or more electrical potential differences.
A Digital Storage Oscilloscope (DSO)
A DSO is also like a conventional oscilloscope except that it uses digital memory to store the waveform. Thus it first digitizes the input analog signal by an analog to digital convertor and di ....etc

Abstract:
This is one of great project based on AVR microcontroller. It use ATmega32 as processor and LCD 128 64 pixels for display. If you need to measure low frequency i thought this project, AVR oscilloscope, will be usefull. Maksimum frequency for AVR oscilloscope is 5 kHz (square signal), other signals (sine or triangle) the frequency is lower ( almost 1 kHz) for having clear view of the signal. Voltage input range is 24V AC / 30V DC.
This project use C language and CODEVISION as compiler. So, it will be more easy to understand t ....etc

Cathode ray oscilloscope: Cross ray oscilloscope, ie CRO is an instrument used to test and observe the constantly changing signal voltages. Usually, it gives a two-dimensional frame of one or more parallel signals as a function of time. CRO device has many applications mainly in electronics and electric. The cathode ray oscilloscope has fast processing and traces the X-Y pattern at a very fast rate.In fact, the cathode ray oscilloscope is very fast X-Y plotters that can display an input signal as a function of time or other signal.
