This is simple led blinking program try it out


This project will blink a LED on Port 2 of any 8051 based Microcontroller

You can open this project 'led test.Uv2' in Keil Compiler

Download Keil for C51 MCUs from http://www.keil.com/

Connect a LED in this way:
Anode of LED should go to VCC via a current limiting resistor can be any value beween 470 Ohm to 1K
Cathode of LED should go to any Port 2 pins of MCU
For 40 pin AT89S52 or similar Port 2 is from Pins 21 to 28

470-1K LED
VCC o----/\/\/\----|>---o Any pin on Port 2


sfr P2 = 0xA0;

void delay()
int i;


void main()
P2 = 0xFF;
P2 = 0x00;

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
