Hi,anyone
If anyone use I2C for several nodes.When I use it,the problem is they can't communication by interrupt,even don't know each other.But for only two node,it shows ok.
anothor problem is :how to deal the bus power supply.If I connect two MCU chips which have their own power supply,the two chip may be heat,even be destroyed.
Can anyone give some advices.Thank you.
