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

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

lpc abbreviation in lpc2148

LPC is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors (formerly Philips Semiconductors). The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals. The earliest LPC series were based on the Intel 8-bit 80C51 core. As of February 2011, ....etc

This project is designed to monitor the LPG leakage or smoke and activate the siren and auto dialer using ARM based microcontroller. LPG Sensor is used to sense the leakage. A buzzer is provided to alert the user in abnormal condition.
The LPC2148 are based on a 16/32 bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 128/512 kilobytes (kB) of embedded high speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at maximum cl ....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
