/* Project: Unit 02 - LCD
Code: unit_02_01_helloWorldLCD.c
Objective: In this project we will work with LCD;
How do you make text appears on lcd screen?
WELCOME TO LCD'S HELLO WORLD!
Note: Select on Library Manager the LCD library fo mokroC PRO for PIC:)

PDL: is a free-format English-like text that describes the flow of control and data in a
program. PDL is not a programming language. It is a collection of some keywords that enable
a programmer to describe the operation of a program in a stepwise and logical manner:
BEGIN
Choose the board to work with (easyPIC or microgenios)
Configure LCD module connections
Configure PORTB as digital outputs
Initialize the LCD
Clear the LCD
Set cursor off
Write text on the first line
Write text on the second line
