#119012 - 4 digit 7 segment display Responding to: ???'s previous message |
Hi..friend..
you should have to multiplex the digits.. In short.. PortA for Segments data(Also DP) PortB 4 bits for digit selection Put the seven segment data on portA for first digit. Activate first Digit. put the code for second digit and select second digit... and repeate this continuously for all digits... this process may remain continuous and change in disply data will be interrupt based. so that you will get the things done. More, please refer Duglass hall for 8086-chapter 9 for multiplexing of displays. If any more help requires then mail or msg me on patoliyarj@yahoo.com. I will try my best to solve your problem. bye n take care.. A Avajo!!!!!!!!!!! |
