Hi,
I want to connect two 8051 (Atmel 89C2051) so
that I can transfer data from one chip to the
other. The data transfer will be only in one
direction as shown in the diagram below, from
chip2 to chip1.

p0.0 of chip 1

p0.0 of chip 2

I want to know how can I connect them using minimum
no of components. I know that the pin which is
acting as input should be set to \'1\'. But what of
the value being read is \'0\'. In that case logic \'0\'
will be connected to logic \'1\' . Wouldn\'t this cause
a short circuit. Is using a suitable resistor between
the pins( to limit the current) is OK ? Any other
suggestion would be highly appreciated.

thanks
Deepak
