Is there a way of I2C access to same slave devices without data loss?

[Surender Reddy]

Hi,
Is there a way to talk to same I2C slave devices from same vendors without changing the Slave address of the devices?

Is it a possible scenario? Did we ever try this out?

Not possible without some kind of multiplexer.

Hi,

What does "from same vendors" mean?
and "without changing slave address"?

***
Is your questing asking about accessing two 100% identical slaves?

How would you do with analog signals with one ADC channel? Or digital signals over one digital pin?
Probably you´d use a MUX.

And with I2C it´s the same. Just use an I2C MUX. Like. TCA9548.
