Hi, I'm planning on seperating an LCD from the PIC and using I2C to communicate between the two, the distance would be 1 metre at the absolute maximum and there will be a mobile phone operating within 1 metre of the setup. Is I2C up for this or should I look at a more robust connection such as RS-4xx? Regards Jean-Michel. -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
