I am wondering about including a flag that indicates that the HAL pins should
be inited from the device, but in general HAL writes every value every thread
anyway, so this would only affect the behaviour of unconnected pins.
Maybe it makes sense for the HAL file to set the pins to a known default
anyway?
To save serial traffic the driver only writes changes (but as HAL pins init to
zero this will generally look like a change)
