Interfacing of 8051 with displays



Interfacing of 8051 with LED

forward voltage drop of LED is from 1.7 to 2.5
forward current of LED is 20mA

89C51(8051) comes under TTL logic families
TTL can sink up to 16mA and source 250uA
The 8051 port pin can sink 1.6mA (3.2mA for port 0) and source 60uA.
To drive significant current, we should arrange our circuits to use current sinking.

Design calculation

The resistor limits the current.
Assume voltage is about ....etc

lpc in matlab code for image

This example shows how to implement a speech compression technique known as Linear Prediction Coding (LPC) using DSP System Toolbox functionality available at the MATLAB command line.

Introduction

In this example you implement LPC analysis and synthesis (LPC coding) of a speech signal. This process consists of two steps: analysis and synthesis. In the analysis section, you extract the reflection coefficients from the signal and use it to compute the residual signal. In the synthesis section, you reconstruct the ....etc

interface lpc 2148 with hc sr04

The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object like bats or dolphins do. It offers excellent range accuracy and stable readings in an easy-to-use package. It operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect). Similar in performance to the SRF005 but with the low-price of a Sharp infrared sensor.

Power Supply :5V DC
Quiescent Current : <2mA
Effectual Angle: <15
Ranging Dis ....etc

RFID based automatic ration shop is novel approach
in public distribution system (PDS) useful for more efficient,
accurate, and automated technique of ration distribution. Public
distribution system also called rationing distribution system is
one of the widely controversial issues that involve malpractices.
The present ration distribution system has drawbacks like
inaccurate quantity of goods, low processing speed, large waiting
time, material theft in ration shop. The proposed system replaces
the manual work in ration shop. The main o ....etc

Touch Screen Computer Displays



Introduction

When most people think about a computer display, many may develop a mental
picture of an output device. However a computer display can function as both an input
device and an output device. A touch sensitive screen provides a computer user with an
input interface that doesn t require extensive computer skills or literacy. This interface,
operates as a pointing device, much like a mouse or an input device much like a
keyboard. Tou ....etc
