4.1. Firmware Update and Compass Calibration

Proper firmware and compass calibration are crucial for safe and stable flight. Follow the steps outlined in the video below for a successful setup.

Steps for Firmware Update:

1. Open the ArduPilot Mission Planner software.
2. Connect the PIXHAWK to your computer via USB. Do NOT click "CONNECT" yet.
3. Navigate to "INITIAL SETUP" > "Install Firmware".
4. Select the corresponding model (e.g., ArduCopter V4.0.7 Quad) to update the latest version online.
5. If prompted "Is this a CubeBlack?", click "No".
6. If prompted "Upload ChibiOS", click "Yes".
7. Wait for the upload to complete.
8. Alternatively, to use firmware V3.X (if V4.0 causes compass issues without an external GPS module), click "Download Firmwares" and select any version below V4.0 (e.g., stable-3.6.9). Find the "fmv2" file and download "arducopter.apj". Then, click "Load custom firmware" in Mission Planner and open the downloaded .apj file.
9. After successful firmware upload, select the COM port in the upper right corner and click "CONNECT".

Steps for Compass Calibration:

1. In Mission Planner, navigate to "INITIAL SETUP" > "Install Firmware Manifest" > "Compass".
2. Click "Start" to begin the calibration process.
3. Hold the PIXHAWK device in the air and rotate it slowly so that each side (front, back, left, right, top, and bottom) points down towards the earth for a few seconds in turn.
4. During the calibration, observe the green progress bar for Mag 1 moving.
5. If using a GPS module with compass (e.g., SE100), ensure it is connected and its direction is consistent with the PIXHAWK during calibration.
6. Click "OK" when the calibration is finished.

5. Načini rada

The PIXHAWK flight controller supports various flight modes, offering flexibility and stability for different applications. The video below demonstrates some of these modes.

Key Flight Modes:

• Stabilize Mode: This is a basic flight mode where the flight controller automatically levels the aircraft, making it easier to fly. The pilot directly controls the roll, pitch, and yaw.
• Loiter Mode: In Loiter mode, the aircraft maintains its current position, altitude, and heading automatically. This mode is ideal for beginners or for tasks requiring stable hovering, such as aerial photography.
• Return to Launch (RTL): This safety feature allows the aircraft to automatically return to its launch point and land. It is particularly useful in situations where the pilot loses visual contact or needs to bring the drone back safely.
• Navigacija po tačkama puta: The PIXHAWK can be programmed to follow a series of waypoints, enabling autonomous flight missions. This is managed through the ground control station software.

7. Održavanje

To ensure the longevity and optimal performance of your Radiolink PIXHAWK Flight Controller, regular maintenance is recommended:

• Održavajte čistoću: Regularly clean the flight controller and its components to prevent dust and debris buildup, which can affect sensor performance.
• Pregledajte veze: Periodically check all cable connections for looseness or damage. Secure any loose connections to prevent intermittent issues during flight.
• Ažuriranja firmvera: Stay updated with the latest stable firmware versions to benefit from performance improvements and bug fixes. Always follow the official update procedures.
• Pravilno skladištenje: Store the flight controller in a dry, cool environment, away from direct sunlight and extreme temperatures, to prevent damage to electronic components.

8. Otkrivanje problema

If you encounter issues with your PIXHAWK flight controller, consider the following troubleshooting steps:

• Compass Calibration Issues: If the compass fails to calibrate or shows errors, ensure you are performing the calibration correctly as shown in Video 4.1. If using firmware V4.0 or higher, an external GPS module with a compass might be required, or you may need to revert to a V3.X firmware version.
• Bez GPS zaključavanja: Osigurajte da GPS modul ima čist view of the sky. Interference from other electronic components or indoor environments can prevent a satellite lock.
• Problemi s povezivanjem: Verify that the USB cable is securely connected to both the PIXHAWK and the computer. Check that the correct COM port is selected in Mission Planner.
• Safety Switch Blinking Yellow: This indicates that the flight controller is not ready to arm. Check for any pre-arm checks that are failing (e.g., compass calibration, GPS lock, accelerometer calibration).
• Nestabilan let: Re-check all calibrations (accelerometer, compass, radio). Ensure propellers are balanced and correctly installed. Verify that the frame type is correctly configured in the Mission Planner.
