|Serial Interrupt using 8051|
|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.
|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.
