I would not either. I2C is good for on card comms but thats about it. (Andy is not using I2C with the Arduino but rather async serial at 1 Mbps. If this is used with RS-422 or better isolated RS-422 it is quite robust) Peter Wallace Mesa Electronics ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
