Hi all,I am not sure if this issue was reported before, but I could not find it.I wanted to use Pixhawk on the Turnigy Integrated PCB Micro-Quad. I followed the following video for the parts and the assemblyhttps://www.youtube.com/watch?v=j46fSNIui7MHowever, I replaced the controller with a Pixhawk. I used the 3DR power module to power the Pixhawk, but cut the thick cables and replaced them with less thick ones that match the wires of…See More

Hi,

I request your advice about the issues below:

1) I want to import all sensor data of apm board (gps, magnetometer...) to matlab/simulink and send trajectory data(a set of 3 axis coordinates of target nodes in order)
2) I want to get speed transfer function of motors real time in order to get PID parameters via matlab/simulink(i know that we can tune PID parameters via mission planner soft. but i want to learn about this method)

 

Which method is useful for the purposes above:

-mission planner soft-matlab connection via serial port

-apm 2.6 and arduimo ide connection via xbee-usb and then arduino ide and matlab connection via serial port. Thank you.
