Hi, I want to establish communication between two micro controllers,which are not having internal I2C arrangement.How to set device adders for micro controllers? I want to transfer data from one controller to other.Please help me in this regard. thanking you, With regards, Bhaskar
if not having internal I2C arrangement. means "no hardware I²C" then get some processors that do. a bit-banged I²C is fairly simple, but an I²C slave is just about the most difficult thing to implement.

can u use mores code?
Do you really mean using MORSE code for multiprocessor communication ???
The simplest way to exhange data, is the UART already installed between the two '51s.
Morse is just an encoding - but it relies on careful timing. So the speed can't be higher than what the receiver is guaranteed to have time to poll (or handle interrupts for).
So Morse is basically one of several "one-wire" protocols possible. The Maxim/Dallas one-wire protocol is another. The common thing for one-wire protocols is that they use timing for both data and synchronization since they have only a single signal to play with.
