Summary of Scrolling Text on LCD by PIC Microcontroller
This article explains how to implement scrolling text on an LCD using a PIC16F877 microcontroller in 4-bit mode. It outlines the necessary software tools, Proteus 7 Professional for simulation and MikroC for programming. The hardware setup includes a crystal oscillator, the PIC16F877 chip, and an LM016L display. The tutorial focuses on using specific C commands, `LCD_SHIFT_RIGHT` and `LCD_SHIFT_LEFT`, to move text across the screen without re-explaining basic LCD interfacing.
Parts used in the Scrolling Text on LCD by PIC Microcontroller:
- Proteus 7 Professional
- MikroC
- Crystal
- Pic16f877
- LM016L (LCD display)
Scrolling Text on LCD by PIC microcontroller is very simple but very important one. For moving forward we need basic knowledge on how to display the text on LCD by pic Micro controller. For that please see my previous post on that “Displaying text on LCD by interfaced with PIC16F877 microcontroller in 4 bit mode” .
Now to start with Scrolling text on LCD by PIC microcontroller in 4 bit mode, we need support of
- 1 Proteus 7 Professional (where we Make your hardware arrangement our project and simulate it to see the result)
- 2 Mikcro C. (here we write the Embedded C Program and build the hex file of that)
So we start with Proteus 7 Professional
To build Scrolling text on LCD by PIC microcontroller in 4 bit mode, we need to add some device in proteus as like in other project we did. Those are
- 1) Crystal
- 2) Pic16f877
- 3) LM016L ( LCD display)
Now how to add, make the interfacing and to see the result of our project how it simulates? See my video in below where I show you step by step.
In Makcro C
See in Makcro C how to display text in LCD I already discus in my previous post at Displaying text on LCD by interfaced with PIC16F877 microcontroller in 4 bit mode . so in this post I not discussing tish portion I only discuss how to scrolling the text. For scrolling the text we have to know some other command those are
LCD_SHIFT_RIGHT (By this command text on LCD shift one bit position in Right)
LCD_SHIFT_LEFT (By this command text on LCD shift one bit position in left)

- What is required to start scrolling text on LCD by PIC microcontroller in 4 bit mode?
You need Proteus 7 Professional for hardware arrangement and simulation, and MikroC to write the Embedded C Program. - Which devices must be added in Proteus to build this project?
The required devices are a Crystal, Pic16f877, and LM016L (LCD display). - How do you shift text one bit position to the right on the LCD?
Use the command LCD_SHIFT_RIGHT to shift the text one bit position in the Right direction. - How do you shift text one bit position to the left on the LCD?
Use the command LCD_SHIFT_LEFT to shift the text one bit position in the Left direction. - Does this article explain how to interface the LCD in 4 bit mode?
No, it refers to a previous post for that information and only discusses how to scroll the text. - Can I simulate the result of my project in Proteus?
Yes, you can make your hardware arrangement in Proteus 7 Professional and simulate it to see the result. - What tool is used to build the hex file for this project?
MikroC is used to write the Embedded C Program and build the hex file. - Is the process of scrolling text considered simple?
Yes, the article states that scrolling text on LCD by PIC microcontroller is very simple but very important.
