I2C Problem
I have a I2C problem.In a I2C,it can control many chips .But how can the master cpu kown which slave chip to work.I read the I2C guide ,but I just not know how to selecet the slave chips.
I saw a example program ,only founde the program sent a address command to de bus.But how it kown the slave chip's address.
I just want to know how to set the address of the chips,so that I can decide which chip to work.
very thanks to !
