It is very simple and easy to understand the project for beginners and is commonly used in several electronic products.

LCD (Liquid Crystal Display)provides a user-friendly interface and can be very useful for debugging purposes.

After completion of this tutorial, you will be able to display data on an LCD using MPLAB XC8 Compiler and Mikro C compiler.

We will provide examples with two Compilers such as MPLAB XC8 Compiler and Mikro C for PIC.

Because we can display characters, numbers and custom characters with ease ( Just by easily programming a module).

Because we send control and data signals to LCD through these IO pins.

Therefore, you should know how to use digital input-output pins of the pic microcontroller.

There are 8 data pins from D0-D7 and three control pins such as RS, RW, and E.

In this tutorial, we have used the 4-bit mode which uses only 4 data lines, thus saving pins of the microcontroller.

So It is recommended to use LCD in four bits mode to save pins of the microcontroller for other applications.

On the other hand, if we use 4-bit mode, we need only 6 GPIO pins.

The only difference between 4-bit and 8-bit is that data transfer speed is faster for 8-bit mode.

Therefore, if you are not able to see anything on LCD after programming, the maximum changes are that you need to adjust contrast with the variable resistor.

This contrast register makes adjust to the voltage applied on the VEE pin.

For MikroC Pro for PIC, we will use the PIC16F877A microcontroller.

In the case of MPLAB XC8, we will develop our own LCD library.

In the contrary, MikroC Pro provides libraries for all modules such as LCD, Keypad, ADC Module, UART module.

Although, you can use see code with other Pic microcontrollers also.

But due to the efficient use of MCU pins, we will be using 4-bit Mode.

I will show you how to assign pins for LCD in the next section.

For instance, in this example, we used the PORTD of PIC18F4550 microcontroller.

Connect RD0-RD3 pins with D4-D7 pins of LCD respectively and other pins with RW, EN, RS and Power pins.
