plz tell me software link ti download circuit design with comp. microcontroller ic 8085,8255 etc. I have the circuit maker soft. but it has not this future.I want this on monday.

 

You can use Proteus to design circuits and download a program for a microprocessor in the simulation but i am not sure if it includes 8085 and 8255.

 

Sounds like you waited a bit too long to start that project. Have you looked into a website hosted by a uC manufacturer? You should be able to copy something from one of them.

 

thanx buddy
