 I use STM32F401RE nucleo board to detect tilt.

I will use same MEMS sensor (ISM330DLC). Three.

But I want to control that sensor in I2C1 Bus. 

I know setting SA0 to distinguish SAD. it's only possible to two devices. 

I need to control three devices.

Help me! Thank you.

Right.

>I need to control three devices.

A: So use other I2C for 3. sensor.

B: Use a I2C mux , to switch the bus to > more I2C "sub-groups" .
