Programming Serial Interrupts using 8051 Microcontroller

Serial Interrupt using 8051
Serial interrupt in 8051 was used to create an interrupt routine by means of sending a character through the UART. It plays a significant role in Embedded system Design where the controller has to perform a certain tasks based on the incoming character through the UART. Before going through this tutorial you must be familiar with Serial Communication in 8051 Microcontroller to get a clear idea about Serial Communication.

Programming External Interrupts in 8051 Microcontroller

External Interrupts in 8051 Microcontroller
External interrupts paves way for the users to interfere the process of Microcontroller externally and force it to execute a specific set of commands. Since the interrupt is generated from a external source it is named as External interrupts and here we are about to use a simple switch button to generate the interrupt to the Microcontroller.

I assume you are familiar with the concept, working and registers involved in the Interrupts, if not kindly go through this 8051 Interrupt introduction and programming

16x2 LCD and Keypad Interface with PIC16F877A Microcontroller

Design of LCD and Keypad Interface to PIC Mircocontroller
Interfacing of LCD and Keypad are one of the important interfacing concepts of PIC microcontroller since both the input and output element can form a complete embedded system design. This tutorial is about teaching you how to get input input values from keypad by polling method and display the input into a 16x2 LCD.
