Blinking a LED using MPLAB X PIC16F877A

Blinking a LED using MPLAB X PIC16F877A

As all the programming lanugages start with a "Hello World" program ,but for a embeded programming its more fun if we start with an optical output

1.Start the MPLAB X IDE

2.Start new Project From the menu bar
 or by  File ->New Project
3.A new window will appear , select Microchip Embedded from the category and Stand alone project from the Projects
proced by clicking Next

4.Select the Device  Midrange 8 bit MCU from the family and PIC16F877A from the Device list

5.Next is selecting the Hardware tool ,select ICD 3 and proceed to Next

6 .Now select the compiler ,for PIC16F877A select Hi Tech PIC compiler

7.Now you are on new project page

 create a new file by clicking on the menu bar or by File -> New File
8.Choose the file type : select  C  from the categories and C main file from the File types

9.Click next and take the source files from the left sidebar

open the file by double clicking Write the C program code their
 for blinking a LED the code is here
