As we discussed in previous pages the functionality of each individual part of the project of Frequency Counter and Pulse Width Measurement System, Cum Digital Clock. Now it is time to discuss the actual circuit diagram of the project based on microcontroller AT89c52.
So here is the Circuit diagram of Frequency Counter and Pulse Width Measurement System, Cum Digital Clock. Introduction of the project is given here.
First of all in this post we are going to list the main components of the pulse width measuring project based on the microcontroller 8052.
List of Componenets of the Microcontroller Project is as follows:
1. The heart of the project is microcontroller 8052.
The microcontroller 8052 is discussed here. The 8052 microcontroller is used for local processing and controling of LCD. The measured resuts are shown on the local liquid crystal display. The microcontroller 8052 is also used to get the incoming pulses and process these, extract useful information from the pulse trains, like frequency, pulse width, duty time, etc. and display these on the LCD. as well as the results are then sent to PC through RS-232.
2. Liquid Crystal Display LCD.
This the main display we used in this project. The project measures the paramters from field or from the incoming pulse trains and then after calculation these paramters are then shown on LCD. The incormation about the LCD is here.
3. Max-232.
As discussed earlier that the measured parameters are displayed on local LCD, as well as these parameters are sent to PC. So there was some special circuitry involved in this phas which is based on MAX-232 IC. The RS-232 can also be used here. The time is also sent to microcontroller from PC. So this is two serial communication though MAX-232. The information about the RS-232 is presented here.
