[Gumstix-users] i2c

[Chander S <ine...@gm...>]

Is it possible to interface gumstix to an i2c master device?  The
reason I ask is because I have a rabbit microcontroller based on the
rabbit 3000 microprocesser (http://www.rabbitsemiconductor.com) and
the only i2c configuration option is master.  I would like to send the
rabbit commands from the gumstix.

This may be possible is if two masters share SCL, one device is set to
master-receiver, and the other is set to master-transmitter.  I do not
think this will work because the master initiates the recieve or
transmit request.

The other option is to make the gumstix slave to the rabbit.  I don't
see this in the i2c-dev.h interface though.

And of course there is an option of writing a i2c slave driver for the
rabbit.  I would prefer to avoid this.

Thanks,
Chander
