Skye2 NANO Quick Start Guide(ArduPilot)

The setup and configuration described in this chapter apply when using the Skye 2 NANO with a controller running PX4 firmware.

Enable

Run QgroundControl>, set the following parameters to save and restart the vehicle.

• UAVCNN_ENABLE Set to Sensors automatic Config
• Reboot
• UAVCAN_SUB_ASPD Set to Enable
• UAVCAN_SUB_DPRES Set to Enable

Multiple Airspeed Sensors

If you have multiple airspeed sensors then you can select which sensor is preferred as the primary source using ASPD_PRIMARY, where 1, 2 and 3 reflect the order in which the airspeed sensors were started:

• 0: Synthetic airspeed estimation (groundspeed minus windspeed)
• 1: First airspeed sensor started (default)
• 2: Second airspeed sensor started

• 3: Third airspeed sensor started

  The airspeed selector validates the indicated sensor first and only falls back to other sensors if the indicated sensor fails airspeed checks (ASPD_DO_CHECKSis used to configure the checks).

The selected sensor is then used to supply data to the estimator (EKF2) and the controllers.

Performing the Calibration

• Select "Q" icon > Vehicle Setup > Sensors (sidebar) to open Sensor Setup.

• Click the Airspeed sensor button.

• Shield the sensor from the wind (i.e. cup it with your hand). Take care not to block any of its holes.

• Click OK to start the calibration.

• Once asked for, blow into the tip of the pitot tube to signal the end of calibration.

[!TIP] Blowing into the tube is also a basic check that the dynamic and static ports are installed correctly. If they are swapped then the sensor will read a large negative differential pressure when you blow into the tube, and the calibration will abort with an error.
