Hello people, i'm in the need of some piece of info that i can't find anywhere..

I'm trying to interface two 89c2051 uC-s over the I2C bus, but i can't find the address for them so they could address each other..

Does anyone know where to get the addresses?
I'm programming in Bascom8051..

Thx for the replyes..

according to me u can not generate hardware address for a microcontroller which does not have on chip I2C..

on this site u'll find I2C routines for dedicated I2C pheripherals only ..(i.e. communication between microcontroller and a I2C device which has its own hardware address)

i'll suggest u to go for microcontrollers which has on chip I2C..in that u can assign the address u want..

all d best

Regards
Rushi D.

you can use uart to connect two 89C2051 instead.
