RC override reset doco bug about mavproxy

[francisvierboom]

By the way I have run into this because I am trying to set off an AUTO mission without the remote control. It only seems to happen following arming by nudging the throttle on the RC. This override allows me to do that nudge programatically - but is there a more sensible approach?

hi , currently im using mavproxy to control my quadcopter. But somehow, i can't override the channels using RC_OVERRIDE_CHANNEL command which is "rc all 1000". The quadcopter seems to have no response at all when i execute this command using mavproxy connected using USB...... Any advice? Thanks

I set up the environment for raspi to control the APM yesterday ,every things seems ok,i can see a lot of data through raspi,so i tried to congtroll the drone by raspi,but unfortunetly,when i type rc 1 1000,there is no response,why?

It seems I solved it

hello ahui9907

Can you control the APM to change the rc signal (pwm) ?

I want to control my apm to change pitch roll.

[ahui9907]

Yes,but i am doing some experiment now. you mean use raspi to control the APM?

@ahui9907, @Benche, we really don't recommend controlling copter using rc-overrides. It's much better to use MAVLink messages to directly control position, velocity, etc. There's currently no support for directly controlling the vehicle's lean angle but we can add that.
I'd recommend joining the dronekit-python gitter channel. https://gitter.im/diydrones/dronekit-python

@rmackay9,now I joined the room,thanks

@ahui9907
Yes , like this: https://www.youtube.com/watch?v=K_Cc3B4xG1c

Maybe I have many question to ask you.

@rmackay9

I know , but i want to control my apm to move right a little (pitch control) .

I don't want to use GPS position to move.

@rmackay9 @rmackay9 I have seen the video you posted, I think it is useful for auto landing accurately, and i am also doing this work , i am familiar with the APM code,now I have connected APM and raspi, I can controll the motor spped freely by typing the PWM value in the python commandline, but infact i am not so famililar with opencv and python language , so i ask my freiend who has worked in ARCAA to do the opencv work, and now I need somebody who is familiar with python to write the code that can controll the APM by sending continuously control conmmand accrding to the opencv-based vison signal.

@ahui9907
I'm from Taiwan . I see your information you are in china.

Can i discuss with you in the future(maybe we can use chinese) ?

[ahui9907]

@Benche do you majored in UAV?

[Benche]

I major in electronic.

I do small project to control pitch and roll to avoid obstacle.

I only need is "controll the motor speed freely by typing the PWM value in the python

commandline,".

But I don't know use which document .

If you can me give some help in the future ,i will very happy.

Thank
