i2c question

Hello to All

Sorry for this newbie question.

I would like to connect this oled screen from adafruit (adafruit.com/product/3527).
Plug in was not a problem on a RPi3b.
Using the last Volumio distrib (2.729) the following command doesn’t show any device

My configuration file (/boot/config.txt)

If i use a regular Raspbian / buster distrib ion the same RPi, the command returns
then this is not a hardware problem, but a configuration one…

Do you have any idea ?

Thanks a lot, and sorry for my poor english, I am french !


Is there anybody having an idea ?

Please :wink:
