MULTIPLEXED 7-SEGMENT DISPLAYS
This tutorial is taken from the book MY EXPERIENCE IN PROGRAMMING AVR MICROCONTROLLER IN C USING WINAVR/AVRGCC. you can download it free from the files section(FILE-AVRBOOK.RAR) of yahoo group-booksbybibin http://groups.yahoo.com/group/booksbybibin/ comments about this book on www.booksbybibin.blogspot.com MULTIPLEXED 7-SEGMENT DISPLAYS Here we use the technique of persistance of vision. i.e, our eye cannot detect what is happening in 1/16 of a second. So any happening within that time will be seen continous by our eye. This technique is used in television, even used to program CRO's for some games.
I am using 74126, tristate buffer to give power supply to the 7segment. You can use
transistors in case of common cathode display. But here I am using common anoder
displays.
