sorry I believe I was not clear. Thanks for the tips but my question is more related to in flight re-center the gimbal position.
A lot of times flying in fpv mode you move the gimbal - pan for instance - and is always hard to find the exact point of controlling the gimbal to the center position - I have a c20-t and you can configure a function called reset or center, you activate one key and the gimbal goes to the center - I saw in the Siyi if you are using the SBus you can assign a channel to re-center the gimbal - but the serial protocol/ardupilot configuration I couldnāt see how to to that.
Hi Juvinski,
Sorry for the misunderstanding! I see your point. I have been writing python scripts to do that using mavlink. Basically I assigned the center location to all three axis and then assign a command to bring them all back to the nuetral. My stuff will not help you and it looks like ardupilot does not have a built in function where you can define the neutral locations and then assign a button to it.
Good luck !
From the title and video, it can be seen that the camera used in the video is an A8 mini.
Firstly, the A8 mini needs to be used together with the randomly equipped shock-absorbing structure, otherwise the complex vibration environment of the body will seriously affect the stability of the gimbal! This is not the correct operating condition.
Secondly, the aircraft model is fixed wing, but real-time airspeed cannot be seen in the video. The maximum airspeed supported by A8 mini is 25m/s. Exceeding it will cause the gimbal to malfunction.
My Siyi A8 Mini was working fine for 3-4 months, and there was NO CHANGE in my drone.
Today, when I powered up the drone, my Siyi A8 Miniās gimbal stopped working randomly after powering up, and it is giving a āhissingā sound, and the pitch axis is vibrating without any control.
It was running on gimbal firmware 0.4.3 and camera firmware 0.3.2 and was working fine earlier.
I have tried updating it to gimbal firmware 0.4.4 and camera firmware 0.3.2.but the issue is still there.
I detected an unusual noise in the video, though I cannot confirm it originated from the A8 mini.
I suspect a potential mechanical fault may be present, which would necessitate after-sales service. Therefore, please contact your point of purchase for resolution or reach out to our technical support team via the official website.
Question on setting an SRx_EXTRA1 parameter 50 (per SIYI manual instructions). If the camera is connected to the flight controller through a network switch (works very well) what should the āxā be set to. Also inspecting the packets via wireshark I do not see any mavlink attitude or other mavlink packets (after setting all occurrences of SRx_EXTRA1 to non zero). Does ArduPilot send mavlink over a link not configured as mavlink?
The āxā here corresponds to the serial port number on the flight controller. Therefore, the cameraās serial port must be connected to the flight controllerās serial port in order to send and receive MAVLink messages.
We need to confirm that you are using the gimbal camera from SIYI.
Thanks for your response. I have a SIYI zr30ā¦ My post stems from attempting to stabilize video at high zoom settingsā¦I have previously had the camera connected via a serial port, and have not had any success achieving the FC controller fusion talked about in SIYI Manuelā¦The ArduPilot DOCS indicate srX_extraX only apply to Mavlink channels, and the serial camera connection is not Mavlink. The āXā refers to the Mavlink channel number not the serial port numberā¦ArduPilot has a custom SIYI camera driver based on the communication protocols based on SIYI docs. From inspecting ArduPilot C++ code, the serial driver sends attitude to camera at a hardcoded rate of 10Hzā¦I switched to a network interface so that I could monitor communications between camera and FC via a program called wireshark. I verified the 10Hz attitude rate, but could not see any mavlink messagesā¦So far I have made some simple mods to ArduPilot/Siyi driver code to output attitude a 50 Hz, and verified the 50Hz attitude in wireshark, but have not been able to get any Camera/FC fusion. Please help!ā Thanks again
Upon verification, the camera does not parse MAVLink data transmitted via the network port. Communication between the ZR30 and Flight Control is exclusively via UART.
For information on integrating flight control data, please refer to Section 3.7 of the user manual.
Have the issue with firmware version 0.0.0. Rebooting camera 4 times didnāt help me. Could you please tell how to fix this?
