Does this apply to GpiodOffset also?

hey @bcr , no for libgpiod what's changed is the gpiochip number, but the offset continues the same.

Just to make sure -- there's an integer property called SysFsGpio that you have added 53 to. There is an additional integer property called GpiodOffset that in the base class has the exact same value as SysFsGpio but is not adjusted here. I do understand that you changed the GpiodChip field also.

pin.GpiodChip = "gpiochip4";
