First of all, thanks for all comments. Just start to working on the arduino and found out I need to know more. 
So my question here is , how do I create multi communication interface such as SPI or I2C?
I have multiple arduino boards and try to create communication between them. Each of them has unique tasks and I have very limited choice.
I understand that SPI use different SS pin to control different slave devices and I2C use address to address this issue. But there are not my options here. So I need to have multiple interfacse to attack my problem here.
My main reference is below two links.
https://forum.arduino.cc/index.php?topic=360026.0
Following the first link, I create a new I2C interface on Pin 11 and 13 as it showed. My default I2C interface on arduino zero is used to communicating with a IMU. Then it freezes. Remove it, it works...
As for the second SPI slave link, I copyed into my works an also freeze as north pole...
I guess I must missing some key pieces to make it work. Would you mind to share your thought about it??
Thanks a million!!
