hi everyone
i got a problem with a cousework
i think it should be easy but im still a newbi so please help me.
i need to connect 2 8086 processor one master and one slave ( our prof calls it like that i dont know...)
sothat i can turn on for example leds on in one of the microp by using the other, using for example porta as input and portc as out. the 2 processors should be connected by a card
it would be very nice if some1 could give me the assembly program for it.
i know i explained it bad, but to be honest i dont get understand it myself....

 

The 8086 do not have ports. It has a address buss and a data buss architecture . What are you referring to

 

er.. right we use a kid and there r the ports and leds etc.

 

If you have one of these - http://en.wikipedia.org/wiki/Intel_8086 - there are no ports. You will need memory and a device like the 8255 - http://www.boondog.com/tutorials/8255/8255.htm - to interface with the outside world.

 

exacty we should use 8255
but the main prob is the program from there do i get the program?

 

You have asked a very broad question that will be very hard to answer. As we do not know the architecture of your system. We like to help in this forum but your request is mission impossible

 

From the master slave setup, I think you need two 8255 PPI, at least this was a topic in my microprocessors class. One 8255 (master) can control total of eight other 8255 (slaves). The 8255 that is master is then connected to the microprocessor.

I do not have any software for it since we did not do anything with this in the lab. For all the stuff we did in the lab, our professor gave us the programs in C and we only had to modify them so I am pretty clueless on the software side.

 

kk thx couz i was about 2 ask if i need two 8255^^
ok if someone knows more about the sowtware side plz let me know thx

 

If you could post the kit you're using you would be a lot closer to getting the answer.

 

ok thx ever1 4 ur help ^^
