airspeed_uadc module

Driver for the Aeroprobe uADC air data computer.

The Aeroprobe uADC 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, altitude, total pressure and static pressure.

Example for airframe file

Add to your firmware section: This example contains all possible configuration options, not all of them are mandatory!

Module functions

Init Functions

These initialization functions are called once on startup.

• airspeed_uADC_init()

Event Functions

These event functions are called in each cycle of the module event loop.

• airspeed_uADC_event()

Periodic Functions

These functions are called periodically at the specified frequency from the module periodic loop.

• airspeed_uADC_periodic()
  • Frequency in Hz: 1
  • Autorun: TRUE
    Periodic function automatically starts after init.
