 		 #134891 - Master ->Slave communication
Dear members,
I need to communicate between two or more slave micro controllers in a controller.

I am trying i2c , having very little success in implementing i2c slave on slave boards.

How do I go about this ? Is I2C slave difficult to implement on software ? what are the other alternatives ?

The data needs to be broad casted to all slaves.

The master & slave board contain 89s52.

Any help / guidance appreciated
