Thanku for ur explanation and code.

8051 Instruction Set

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. Middle leg of the variable resistor is connected instructionn PIN 3 and other two legs are connected to voltage supply and Ground. Learning and Practising or practising and learning simultaneously ensures good progress. In the meantime, please arrange the following Setup: Diagrams of this post. It belongs to Microcontrollers.


Arduino Forum is very resourceful in this regard. Standard-sized Breadboard 1 3. Generally this is set to 0, because we do not have need to read data from LCD. After learning i can easily switch to AVR’s? And we will set it to 0 if we are sending some command instruction like clear the screen hex code So imstruction let’s understand the 16 pins of LCD module. Getting Started with Microcontroller.

In fact, I have no idea about the pricing and vendor of the Learning System of this link Log in or register to post Comment. Check your circuit connections again. AT89S52 Microcontroller 2 The LED1 blinks thanks Mr.

Blinking LED1 connected at the P1. As I have a huge interest in microcontrollers.

Instruction Set

An In-system Programmer that supports 89S52 could be a useful gadget in this case; but, the gadget is rarely available. And set it to 1, if we are reading from LCD module. 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 socket of the programmer, finish the programming, put it again zt89s52 the breadboard, and then testing.

Function inxtruction has been created to create delay in milliseconds and called frequently in zet program, it is called so that LCD module can have sufficient time to execute the internal operation and commands. Contrast Setting, connected to Vcc thorough a variable resistor. But I think beginning with will help me in future? Some important command instructions are given below: Pin 3 V0 is connected to voltage Vcc through a variable resistor of 10k to adjust the contrast of LCD.
