I did search in the forum but I did not find an answer yet…
why do we have to enable Vext to properly read a device on I2C bus?
I have a couple of sensors powered via Vdd (3.3v) … basically always on.
If I do not turn on Vext before probing them I won’t be able to read the values.
I do not understand why do I need to enable Vext to use I2C even if the sensors are not powered by Vext…
