FINAL YEAR PROJECT 2 (WEEK 2): LCD Display Programming

Objectives:

1) To construct circuit of  LCD display.

2) To build a program using C++ language 

Method:

1) using Proteus 7 Professional software to construct circuit

2) using KeilVision4 to write the program

The program has been written and compiled. The HEX file is loaded to the circuit. The simulation is running to demonstrate the system operation. Below is the circuit which had been running the program:

Conclusion: 

This week I learn how to do the program for  LCD display. I learned that the program need to start by declared the input pins that had been used in the circuit. To display the word or character on the LCD display, we need to know the position of the character based on the LCD command codes table. The LCD pins also plays an important because if it not connects well to the microcontroller, it will not display the word on the LCD.
