'ARSPD_PIN' Parameter missing

I’m trying to use analog airspeed sensor instead of digital one. For that I need to set this ARSPD_PIN param to 15. But I’m unable to locate this in current firmware. Is there any other way to use analog airspeed sensor for this firmware?

For the analog airspeed you need to set “SENS_DPRES_ANSC” to the right value for your sensor. Otherwise no differential_pressure messages are publish.
There is no ARSPD_PIN parameter.
