Frequency Generator 8051 Project README

Project Description

Frequency Generator :

This project is a frequency generator that uses a keypad to input a frequency value, which is then displayed on a 7-segment display. The frequency value is used to generate a square wave, which is output through a pin on the microcontroller. The program uses interrupts to detect when the square wave should be toggled on or off. The program runs continuously, waiting for input from the keypad and updating the frequency value and 7-segment display accordingly.

Frequency Counter :

Bonus extra project: this project is an Arduino frequency counter that uses a library called FreqCounter to measure the frequency of an input signal. The frequency is displayed on a 16x2 LCD screen in either Hz, KHz, or MHz, depending on the magnitude of the frequency. The program initializes the LCD screen and sets up the FreqCounter library with calibration and gating parameters. It then enters a while loop that measures the frequency of the input signal using the FreqCounter library and displays the frequency on the LCD screen in the appropriate units. The program uses delay functions to control the timing of the measurements and display updates. this project was used to verify the previous Freqencty generator project. Also, Proteus Simulation is Provided.

Project Overview

The purpose of this project is to develop an embedded system that generates a square wave of a specific frequency using a keypad and a 7-segment display. The goals of the project are to allow the user to input a frequency value using the keypad, display the frequency value on the 7-segment display, and generate a square wave of the specified frequency. The key features of the system include the use of interrupts to toggle the square wave on and off, the ability to update the frequency value and display it on the 7-segment display, and the use of a keypad for user input.

Hardware Requirements

8051 microcontroller, Keypad, output signal, LCD, Arduino

Software Requirements
