Hi,
in a similar vein, I want to use two Amphenol NPA sensors on same I2C bus.
I want to re-program address of one part in-circuit.
For this application the Application note states to use:
“Application hardware configured to allow isolation of individual sensor for programming.”
What exactly does this "isolation" mean.
- I2C Mux/Bridge ?
- Jumpers removed/inserted ?
- Power isolation. (i.e. is removing the power from one sensor a correct way to isolate or will the un-powered device screw up the I2C communications to the other device ?)
Since the sensor does not have a reset pin, I guess we do need to switch power to the device ?
