You need to understand the I2C bus!

standardics.nxp.com/support/ … cation.pdf

I2C is a Bus - that means that it can be shared by multiple devices.

Whenever you have multiple devices, you obviously need some way to identify & select one specific device - this is what the Slave Address is for.

The slave address of your particular device will be found in its Documentation


thanks a lot!
