In my application 3 identical modules are their.Each module having one controller and one keypad. same manufacutrer of controllers and Keypads are used. If i press any one of module then the same operation will also perform in the other modules.
For Ex: one module having the MC1(controller) and KP1(keypad),similarly MC2 ,KP2 and MC3,KP3. If i pressed the KP1 of right button then KP1 should inform to KP2 ,KP3 and KP1 of operation should performed in KP2,KP3 .
If i pressed the KP2 of right button then KP2 should inform to KP1 ,KP3 and KP2 of operation should performed in KP1,KP3 . If i pressed the KP3 of right button then KP3 should inform to KP1 ,KP2 and KP3 of operation should performed in KP1,KP2 .
i think any one of keypad acting as master depends on pressing the keypads and remaining other keypads are acting as slave mode.
please help this matter

Is this is a school project with many people asking the same question, or why several threads?
This is same question as: http://www.keil.com/forum/docs/thread13857.asp
And I'm pretty sure I have seen a third thread - either here or on whttp://www.8052.com.
