hi everyone,
Tell me which driver IC (like BCD to 7 segment latch) we should use to interface between AT89C51 (microcontroller) with 3 digit seven segment display (having 12 pin).
Also how I can do switching with transistors with single port of microcontroller simultaneously when other main programmed is also running in the microcontroller.

Googling "7 segment driver ic" gets many returns - http://www.play-hookey.com/digital/experiments/seven_seg_driver.html

 

Hello,

Do you know the type of the display?
A link to the datasheet would help.
Is it CA or CC?

Greetings,
Bertus

 

Hi

You have to use IC 7447 to interface 7 segment display. Here is the article for interfacing seven segment display. Exact circuit diagram and codes are given. Follow the link: http://electrofriends.com/articles/...rfacing-7-segment-display-using-7447-decoder/

 

I hope my webpage http://www.shree-electronics.com/interfacing_multiple_7_segment_displays.htm will help you.
