If in doubt, clean the build and update submodules.

@AndKe
@joshanne Thank you .. I did --init --recursive the submodules, but did not think of clean, that fixed it..

hi all
I intend to use SPI interface(a binary string of IO data) instead of PWM Input/Output data
is there any concern in both Ardupilot hardware-software point of view if all Input/Output PWM be disabled

Hi guys,
I have been looking into the new Arducopter 4.0.7 and seems like the logic to choose a primary compass has been changed after 4.0.3. The COMPASS_PRIMARY parameter does not exist anymore. Can anyone tell me why did we do that? And how can I choose a certain External compass as primary using the new parameters COMPASS_PRIOx_ID. On looking at the code it seems like it is choosing it based upon devid with 1st order priority, set automatically if 0.

Hi All, I have modified Ardupilot code to add my own library for an algorithm. This algorithm reads a .json file and performs few calculations. The sitl build is successful, however when I launch a mission I get "can not open .json file" error. Any ideas how to use json files in Ardupilot code?

What is the principle of this autotune process? Is there any theory or literature that can be referred to; I don't understand the meaning of ‘bounce back’. I can't understand the adjustment principle of D value

I am trying to receive Mavlink packets in Matlab by forwarding the Mavlink stream from a cube black through mission planner. I read that a connection can be made via the UDP port from the wiki and documentation. However, I am still new to all this so if anyone can direct me to a more detailed instruction would be appreciated.

@PRIMETSS
@TL-4319 MP listens to UDP port 14550 (default) MAVLink and any MAVLink data sent to this port will trigger MP to automatically connect and receive data.
But I'm unsure what your question is?

First I just point out that the ardupilot chat have moved to discord: https://discord.gg/xdKxsHv3F2
I can't answer your question, I don't know how mavlink forwarding with mission planner works. However, if you don't find the answer and want a different way of duplicating mavlink streams to multiple endpoints, you can consider mavlink-router: https://github.com/mavlink-router/mavlink-router/releases/tag/v2 or mavproxy: https://ardupilot.org/mavproxy/docs/getting_started/forwarding.html. Both of these are simple ways of of duplicating the mavlink stream such that mission planner can use one and matlab can use the other.

@PRIMETSS I sort of figure it out already but thanks anyway for the help. And let's move this on discord

Hello, I was wondering if there is a way I can use the send_text debugging feature to send a message to a companion computer instead of QGC. Thank you.

Just a quick question...

How do we build a completely new? For example, assuming I made a folder "ArduCopter2" with all the desired .cpp/.h, with one of them having the main function.

Thanks.

Yes, isn't that a paradox ? ardupilot uses non-free Discord spyware (that unless virtualized, spies on all kind of processes all the time it is running . - and a well used malware distribution platform.)
it's a shame.

Hey everyone. Did anyone tried or is it possible to takeoff a ardu UAV from a hill top and landed at down hill in an autonomous ( way point) mission? Basically I want to land the UAV at a co-ordinate which is having altitude bellow/less then the home/take-off altitude in an autonomous mission..

If it is possible the how we can archive that without any distance sensor?
( Currently we are not using any distance sensor)
