Control Via UART from PC
  • gows007
    Hello,
    I am an absolute beginner.
    Is it possible to send serial commands directly via PC through the UART ports without using the GUI.
    I can connect the PC to the controller via UART ports and run commands via the GUI.
    Can anyone please tell if it possible to send commands without GUI. I want to control the gimbal using scripts.
    I am using SimpleBGC 32 bit controller

    Thank You,
    Best Regards,
    Gowri

    Yes it is possible but you need some application (developed by you or someone) taking care of the protocol, See the Serial API documentation.

    Thank you..
    Connected it and getting the status. I am able to turnoff the motors serially. However CMD_CONTROL is not working
    eg : 3e 43 0d 50 01 00 d8 00 48 00 00 00 00 00 00 00 : This does not control the motors. Can anyone suggest if anything is wrong in the hex values above.
    It is same as :
    • CONTROL_MODE – 1u
    • SPEED_ROLL – 2s
    • ANGLE_ROLL – 2s
    • SPEED_PITCH – 2s
    • ANGLE_PITCH – 2s
    • SPEED_YAW – 2s
    • ANGLE_YAW – 2s

    It was a stupid mistake. I did not add the body checksum at the end. Now its working fine

    Hello, I know it's an old thread but I just bumped into it.
    I'm trying to communicate to my Gimbal using serialApi and Python.
    I can switch motors on/off, I can read parameters, I can play with beeper... so communication is fine.
    Now I want to control motors using CMD_CONTROL but documentation isn't very clear.
    I tried to enter the raw string used by gows007 ("3e 43 0d 50 01 00 d8 00 48 00 00 00 00 00 00 00 00") and I see that it works, but I simply can't understand how you composed it. :-\
    How can I specify angle, speed and so on?

    Though the interface is somewhat complicated it is all explained clearly on the Serial API, and there is also excables.

    What do you want to do, I do not understand. Controlling Pan, Tilt and Roll is easy.

    Just look at the tutorial https://www.basecamelectronics.com/serialapi/

    You need to build the complete message on your code.

    Thank you. I found some tutorial and now I'm able to control rotation!
    By the way, now I'm stuck on converting negative values into byte arrays, but I think this problem is on python side. ;)

    Hello Dagord,
    I know this is an old thread, but I'm having a lot of issues with my control rotation, could you please share the tutorial you found please?

    Thanks in advance
