Hi, What is the best way to get two pics to communicate to each other? I2C or SPI, or is there anything else. Does anyone know where I can get code for either of these methods and a circuit diagram of the connection between the two PICs and other components needed for the circuit. Thanks Andrew Scott. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
