Hi there

I would like to use I2C to communicate with a 16C84.
The 16C84 will wait until it receives a request for
some data. Once it has received the request it gets
the data it was asked for. The problem I have is that
the data takes about 1 second to obtain. Is there a way
I can get the master that sent the request to wait for
the PIC without the PIC becoming the master and
transmitting the data back.

Does the I2C protocol define a way of communicating with
very slow devices on the bus?

Maybe I2C is not the best protocol, please comment.

Regards

Gavin
