In today's technologically driven world, the ability to create custom electronics projects has become increasingly accessible. One fascinating endeavor in this realm is building your own microcomputer using a PIC16F877A microcontroller. While it might sound daunting at first, with the right guidance and resources, it's a rewarding journey that offers valuable insights into the world of embedded systems and microcontroller programming.

Why microcontroller called a microcomputer?

A microcontroller earns its moniker as a "microcomputer" due to its miniature yet potent computing capabilities. Equipped with a CPU, memory, and versatile input/output ports, microcontrollers resemble traditional computers on a smaller scale. They boast programmability, allowing developers to code in languages like C or assembly to fulfill specific tasks. Often integrated onto a single chip, microcontrollers serve as self-contained computing units, particularly prominent in embedded systems where they efficiently manage dedicated functions. While diminutive in size, microcontrollers pack a punch in functionality, earning them the designation of microcomputers.

Understanding the PIC16F877A Microcontroller

The PIC16F877A microcontroller, manufactured by Microchip Technology, is a versatile and widely used component in electronics projects. It features a robust architecture with ample memory, multiple I/O ports, and various built-in peripherals, making it ideal for a range of applications.

Circuit Design and Prototyping

In the schematic, I will show the complete Microcontroller Master Trainer Diagram. Multiple sections are included in this diagram. Power Supply Unit, Microcontroller Biasing, 8 LED for Binary Data check, 7-segment Display Interfacing, LCD Display Interfacing, Push Button for Input Data Check, Voltage Divider section, etc.

Design the circuit for your microcomputer project, taking into account the connections required by the PIC16F877A microcontroller and any additional components. Utilize a breadboard for prototyping, allowing you to test and iterate on your circuit design before finalizing it.

Here is the PCB Design Section:

This is the PCB Design Section. I am using a Double-layer PCB board which is ordered from PCBWay. 

Here I am showing the 3D Design section.

After Completing the Hardware section we need to program for PIC16F877A Microcontroller IC. I am just sharing a sample program for testing your Microcomputer. 

Testing and Debugging

Testing and debugging are integral parts of the development process. Use the debugging features provided by your IDE and programmer to step through your code, inspect variables, and identify any issues. Additionally, verify the functionality of your circuit by testing different scenarios and inputs.

I am using the CCSC Compiler to compile my code.

With the development environment set up, it's time to start writing code for your microcomputer project. Begin with simple programs to blink LEDs or read input from switches to familiarize yourself with the PIC16F877A's capabilities. As you gain confidence, you can explore more complex functionalities, such as interfacing with external sensors or driving displays.

Code:

#include<16F877A.h>

#use delay (clock=20MHz)

#FUSES HS

void main()

{

while(true)
