Turn with the camera

Pan over 1000–2000 µs starts at 0 degrees. The stored range is -360 to 360 degrees, in steps of 10. The hint says a 180 degree servo is 180, a negative number reverses the direction, and 0 means off. The footer says that with a camera on a pan servo, the home arrow and HUD turn with the camera. It also says this is not for continuously rotating servos.

The picture uses that hint as a straight line. It treats the travel number as the degrees between 1000 and 2000 µs, with 1500 µs in the middle. Travel 0 keeps the arrow at 0 degrees at every camera pulse, and the lamp says Off. Travel 180 with the camera still at 1500 µs keeps the arrow at 0 degrees, but the lamp says With the camera, because the travel is no longer off. Move that camera to 1750 µs and the arrow turns 90 degrees. Move it to 2000 µs and the arrow turns 180 degrees. The same 1750 µs with travel -180 turns 90 degrees the other way.

The picture stops at the same -360 to 360 the field allows. It does not draw the servo index, the 10 second warning, or the degrees label. Those are the fields that appear under the travel once it is not 0.

Pan servo index starts at 0 and runs from 0 to 16. The hint says 0 is the first servo. It is hidden while the travel is 0, so the demo does not ask which servo until you enter a travel. INAV servos is where the servo outputs themselves are set. This index only tells the OSD which of those outputs is the camera pan.

Warn when off centre by starts at 10 degrees and runs from 0 to 45. The hint says the pan offset element flashes after 10 seconds within this angle but not centred, and that 0 means off. The 10 seconds is the delay in that hint. The 10 degrees is the starting angle, and you can change the angle without the hint changing the delay. Show pan angle starts off. Its hint says it puts degrees next to the pan offset element. OSD alarms is a different card. Those alarms flash altitude, RSSI and the other elements. This warning flashes the pan offset element only.

The horizon card is also different. OSD horizon sets camera uptilt so the horizon line sits where the camera looks. Uptilt does not turn the home arrow when the camera pans. The video system only changes the character grid. Leave this travel at 0 if the camera does not pan.

Open the OSD tab on INAV and find Camera pan servo. The card is there when the flight controller has this setting. Chrome or Edge connects over USB or Bluetooth. Android adds Wi-Fi. iPhone uses Bluetooth or Wi-Fi and has no USB host. Enter the servo's travel, check the arrow turns the way the camera turns, then save.

If the arrow turns the wrong way, make the travel negative. If the arrow turns when the camera is fixed, set the travel back to 0. A continuously rotating servo is the case the footer tells you not to use here.
