Assembly Language is practised, as westfw has noticed, by the serious programmers. Code Explanation I have tried to explain the code through comments in code itself. So first let’s understand the 16 pins of LCD module.

Function msdelay has been created to create delay in milliseconds and called frequently in the program, it is called so that LCD module can have sufficient time to execute the internal operation and commands. Getting Started with Microcontroller. AT89S52 Microcontroller 2 I also needed a 4MHZ crystal to upload the hex.

And set it to 1, if we are reading from LCD module. An ISP Programmer allows uploading codes into the target MCU in an interactive way for as as many time as much is required without removing the chip from the system. Some important command instructions are given below: I would like to see the photographs of your gadgets.

Agree with you harish kumar If you got the solution kindly share with us. And control pins RS, RW and E to the pin 12,13,14 pin 2,3,4 of port 3 of microcontroller respectively.

A pulse of ns should be given. After learning i can easily switch to AVR’s?

Can I use blue character display instead of green. I am just curious about the At89S Circuit diagram for LCD interfacing with microcontroller is shown in the above figure.

Introduction to Microcontroller. Moreover, learning process of 89S52 using ROM Programmer is a cumbersome one — you need to take out the MCU from the breadboard, put it into the ZIP insyruction of the programmer, finish the programming, put it again on the breadboard, and then testing.

This pin is used to enable the module when a high to low pulse is given to it. Check your circuit connections again. Middle leg of the variable resistor is connected to PIN 3 and other zet legs are connected to voltage supply and Ground.

The above video shows lcd interface on bread board Can this project be shown on general purpose board??? And we will set it to 0 if we are sending some command instruction like clear the screen hex code GolamMostafa Edison Member Posts: Now xet me how to program in C.


I have used these Pins in above circuit. I know how to program an Arduino. An In-system Programmer that supports 89S52 could be a useful gadget in this case; but, the instructino is rarely available. Contrast Setting, connected to Vcc thorough a variable resistor. Get Our Weekly Newsletter! But I think beginning with will help me in future? In the meantime, please arrange the following Setup: TIP is also creating problem during stand-alone programming.

Log in or register to post Comment. Will you please type it in “C” language? Arduino Forum is very resourceful in this regard. Learning and Practising or practising and learning simultaneously ensures good progress.

It belongs to Microcontrollers.

8051 Instruction Set

Push auto spring return Switch Breadboard Mountable 2 Diagrams of this post. At the same time, you may also practice the programming of 89S52 MCU. To be honest I am not understanding the code.

Click here3 for an introduction to Microcontroller. All the pins are clearly understandable by their name instructoon functions, except the control pins, so they are explained below:.
