i saw that many of the beginners are facing problems with seven segments so i have made a small c code which will help you to know more about the seven segment multiplexing technique the rar file contains source code and isisi simulation file

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;

Does anyone have microcontroller programming software for STC15F104W (core 8051, 4 k, 128 byte, 6 I/O pin, UART ... DIL8), that works?
