The communicatory question between pixhawk and raspberry pi3


(DS Wang) #1

Hello! I’m DS Wang

I’m researching in this page
http://ardupilot.org/dev/docs/raspberry-pi-via-mavlink.html

I had already finished the part of “Setup th RPi” and “Setting up the Pixhawk”
And the network had been finished, too.

I built a linux system on vmware.
And I used PuTTy to connect the RPi by SSH on linux system above.
The required packages had been downloaded and installed already.

But…I have a question now.
When I used this command
“mavproxy.py --master=/dev/ttyAMA0 --baudrate 57600 --aircraft MyCopter”
It showed these information like the picture

Does anyone know how to solve it?
I appreciate your help!

How is the Pixhawk connected to the Raspberry Pi? USB? If you are using USB, you should use /dev/ttyACM0 for ‘master’, if you are using the RX/TX pins on the Raspberry Pi, make sure you have disabled the console login on the serial interface.

Hello! Jacob!

I connected the RPi and the pixhawk by using the RX/TX pins.
If I disable the console login on serial interface, the “enable_uart” will be set 0.
But this note show I need to set it 1

How can I do?

Thank you!

DS

Does anyone know the solutions of this problem…?
Appreciate for your help!!!

You need to do two separate things:

  1. Enable the serial interface with ‘set enable_uart=1’
  2. Disable console output on the serial interface, there are instructions to do this here.

Does ardusub-3.4 support telem1/2 communication with pixhawk?

Genius!!!
I solved this terrible problem !!!
They connected with each other, and they can give command to the other one!!!
I can control pixhawk by RPi3 !!

Jacob! I really appreciate for your help and comments!!!
Thank you very very much !!!
