Dear,
I am thinking of adding Raspberry screen to my setup witch consists of Rapsberry Pi 3 B and a BOSS DAC. As I checked on the datasheets of BOSS DAC, DAC already uses SDA and SCL. But at the same time screen would need SDA and SCL. Is there any workaround for that?
Thanks
It works 
It just needs to be connected correctly.
