LCD Interfacing With Keypad PIC16F877A FlowCode Microcontroller Programming And Simulation

In this sample project we are using Programming Software FlowCode for Programming LCD ( Liquid Crystal Display ) With Keypad and Testing And Interfacing with PIC16F877A.It shows how to use and simulate and program Keypad with LCD for use in different projects.In this Project we are testing Keypad and outputting binary values to LCD ( Liquid Crystal Display ).Varying the delay and write-erase sequence can be manipulated to get desired result.

Above is the Flow code program Snapshot:

LCD (Liquid Crystal Display 16X2):-

Its screen is an electronic display module and find a wide range of applications. A 16x2 LCD display is very basic module and is very commonly used in various devices and circuits. These modules are preferred over seven segments and other multi segment LEDs.
The reasons being: LCDs are economical; easily programmable; have no limitation of displaying special & even custom characters (unlike in seven segments), animations and so on.


A 16x2 LCD means it can display 16 characters per line and there are 2 such lines. In this LCD each character is displayed in 5x7 pixel matrix. This LCD has two registers, namely, Command and Data.

Keypad Introduction:-The invention of the keypad is attributed to John E. Kerlin, an industrial psychologist at Bell Labs in Murray Hill.A computer keyboard usually has a small numeric keypad on the side, in addition to the other number keys on the top, but with a calculator-style arrangement of buttons that allow more efficient entry of numerical data.

This number pad (commonly abbreviated to "numpad") is usually positioned on the right side of the keyboard because most people are right-handed.

The keypad of a calculator contains the digits 0 through 9, from bottom upwards, together with the four arithmetic operations, the decimal point and other more advanced mathematical functions.
