OTF! airspeed/flow angle sensor
Driver for the Aeroprobe On-The-Fly! air data computer.
The Aeroprobe On-The-Fly! air data computer measures air pressure from a 5-hole pitot tube and can write resulting data to an SD card or transmit it through an UART. It outputs speed, angle of attack, angle of sideslip and altitude.

Module functions
Init Functions
These initialization functions are called once on startup.
Event Functions
These event functions are called in each cycle of the module event loop.
Periodic Functions
These functions are called periodically at the specified frequency from the module periodic loop.
- airspeed_otf_periodic()
- Frequency in Hz: 1
- Autorun: LOCK
Periodic function automatically starts after init and can't be stopped.
