I2C working, but disabled on Raspbian
-
Hi,
I've noticed that after installing EVOK, I2C is disabled on Raspbian, but still I can communicate with I2C devices.I2C disabled in RP4 settings:
I2C devices:
i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- 18 -- -- -- -- -- -- -- 20: 20 -- -- 23 -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: 50 -- -- -- -- -- -- 57 -- -- -- -- 5c -- -- -- 60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- UU 70: -- -- -- -- -- -- -- --
I wonder how this is possible. Is there some electronic element, which is handing I2C communication on UniPi 1.1? If yes, what is default speed of it?

Hi @mglowinski,
the I2C is enabled in a standard way by device tree overlays. The tool you are using (Raspberry Pi Configuration) probably expects the settings in their own way and don't understand the ours. -
@Martin-Kudláček Do you maybe know how i can check current speed of I2C, which is set over device tree overlays?
