Have recently been playing around wiith i2c on the Pi 3 and can enable the i2c to work by using the old "stick usb in with modules folder and i2c-bcm2708’ this works fine on the Pi 3 but unable to get to work on the pi4 under the Hassio envirment.
I suspect the pi 4 has different i2c configuration ( chip ). Anybody had any luck enabelling the i2c on the RPi4.
On the Working RPi3 Im using Hassio system version 2.12 ( production ) but the
none working RPi4 is using Hassio SystemVersion 3.5 ( Staging ). both 32bit.
Any Help appreciated. dave
