Dear all,
I have one master mcu (atmega32 ) and a pc , other slave mcu and input and output devices. I am able to connect pc rs232 with the master mcu. And I will connect the slaves to the master at SDA and SCL pin. But the proble comes when I need to connect ds18b20 to any mcu. As long as I know this sensor is always tied to SDA of mcu but that is already occupied by the slaves. So is there any way to connect ds18b20 temperature sensor to any pin of atmega32?
