Right ? > There can only be one master at a time transferring data on the bus, but you can hook up as many masters as you like - you have to take care of arbitration though (i.e. get lost when some other uC transmits data). But beware, in the early days of my i2c bus driver I managed to erase the eeprom of my TV that stored all the timing values for various chips. Luck it was still guarantee time ;) Simon - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu Please read the FAQ at http://www.tux.org/lkml/faq.html | ||||||||||||
