Advance LED display

I did some betterment in Led display. By using 8051/52, this display is working smoothly. All the code and the character generation is done by C. I used only 15 pins of Micro-controller for this display. Another important component used here is 74HC595. To use minimum amount of PINs, I used parallel to serial conversion. 74HC595 is basically used as a parallel to serial converter.

8x8 LED Display using 8051 and c

Basic Idea:

Creating simple things is always good for a learner like me. I created a simple Led display using 8051. Total pin used is 2 ,for character generation. So, as we can see we can use 2051 for this kind of display. One set of pin is to scan through row and another set of pin to handle LED (On/Off) by column. The basic catch behind this circuit is serial data transmission, which makes this project cost effective.
