I am trying to come up with a simple project using the ppi chip and the 7-segment display. Thought of doing just a 60sec countdown timer using two 7-segment display and a ppi chip. Can i get help with the assemble code for that. thanks
If it's an 8086, you will need all kinds of support to get it to run - RAM and ROM memory, several interface IC's. For what you're after, a PIC or AVR microcontroller would be way less trouble.
For a countdown timer, a 555 plus a couple of counters would be the simplest way to go.
