Add a new airspeed sensor on Pixhawk

Hi all,

I’m trying to use a new kind of airspeed sensor. The data comes out from the sensor is not static/dynamic pressure but airspeed itself and it’s using UART.

To integrate this sensor into px4 system, where should I look into and how the driver should be written?
I am a kind of newbie programmer so any tips would be appreciated.

Thank you.

As an example you can look at this distance driver which also reads from a UART:

Then you can publish the airspeed data to the uORB airspeed topic instead of the distance_sensor topic:

Thank you for tips! I’ll give it a try.
