Led Control by Matlab and Massage Display on Lcd Serial Communication and Pic 16f877a

MATLAB Serial Communication, for quire contact: [email protected]

LED control by MATLAB and MASSAGE display on LCD, RS232 SERIAL COMMUNICATION, and PIC 16F877APIC16F877A is an easy micro controller for the beginners

Here in project:

1) How PIC switches to TWO LEDS from MATLAB Graphic User Interface2) HOW we use PIC in Serial communication3) How LCD is used with PIC 4) How PIC is connected with RS232 PORT of PC

Than the micro controller read input from the virtual terminal an than display on the LCD and also Switch on the LED

a. MickroC PRO // for programming of MICRO CONTROLLERb. Proteous 8 professional //For simulation of CKT and Design c. MATLAB 2009 // for controlling and sending Control commands for CKTd. Virtual Port Driver 6.9v // for generation of Pair of virtual ports on your system

BEST OF LUCK.

Code for MATLAB LED GUI:



CODE:function varargout = LED(varargin)% LED M-file for LED.fig% LED, by itself, creates a new LED or raises the existing% singleton*.%% H = LED returns the handle to a new LED or the handle to% the existing singleton*.%% LED('CALLBACK',hObject,eventData,handles,...) calls the local% function named CALLBACK in LED.M with the given input arguments.%



% LED('Property','Value',...) creates a new LED or raises the% existing singleton*. Starting from the left, property value pairs are% applied to the GUI before LED_OpeningFcn gets called. An% unrecognized property name or invalid value makes property application% stop. All inputs are passed to LED_OpeningFcn via varargin.%% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one% instance to run (singleton)".%% See also: GUIDE, GUIDATA, GUIHANDLES
