Hello
i have a HifiBerry AMP2 and a Oled Display 128x64.
as i did understand both use the i2c to communicate.
is it possible to use two device on the i2c, just asking because my oled display i not working.
and on the AMP2 which pin is still possible to use for other device or the AMP2 which Pin do it need?
have a nice day

If they use different I2C addresses it should work. However, if the board uses it's own pull-ups this might cause trouble.
HiFiBerry team Merci for your feedback. would it be possible to change the address of the display?
And the Board itself only need
gpio2 (SDA1 12c) gpio3 (SCL1 i2c) and Power 5V or 3.3V to power the raspberry?
Have a nice day

You need to check the datasheet of the display for this information.
found it
and what address needs the AMP2?
Just run
i2cdetect -y 1
to see the I2C addresses in use
