This very much depends on the hardware you are using. The limitations on what pins can be used as ADC pins, and under which conditions, are different from MCU to MCU. So it's very difficult to design a generic API that could be part of embedded-hal. At least if it should provide more than just a single "read ADC pin now" method.
