Interfacing between two microcontrollers

[Sudhp]

hi guys......
I m working on At89s52 microcontroller....
I have to interface two microcontrollers by using I2C protocol....
Plz suggest how can I do this.....

Hey,refer to this link**broken link removed**

I have to interface two microcontrollers by using I2C protocol....

1. Why?
2. There's no hardware I2C interface built into 89s52
3. I2C has to be emulated in software. That's almost easy for master side, more difficult for slave. Most software I2C libraries are supporting master mode only

Thanks for the reply......
Then what should I hav to do for this....
and how can I achieve my goal........

If you really want to use I2C, then use a MCU that supports I2C to make your life easier.

Or use serial port instead.

best and easy way use UART communication....
