serial baudrate in MinimOSD

Posted by Alex.CCCP on June 22, 2012 at 3:57am

Hello.

I have MinimOSD v1.1 and it works fine when APM telemetry is configured for 57600. But my XBEEs work on 9600 only. So if there is a possibility to change OSD's serial baudrate to work on 9600 ?

Where can i get the firmware source and which parameter to change there?

Thanks!

    I got a problem with OSD GUI reporting "Failed to talk to bootloader". I use all 6 pins from sparkfun FTDI adapter got, and autoreset works for me.

    Arduino 1.0.1 works fine, i have uploaded code i have taken from SVN and autoreset does work when i use Arduino to upload code.

    GUI complaints all the time, regardless of what done to OSD, any ideas?

    ok, got the source from "svn checkout http://arducam-osd.googlecode.com/svn/trunk/ arducam-osd-read-only" repository.

    In ArduCAM_OSD set:

    "

    #define TELEMETRY_SPEED 9600 // How fast our MAVLink telemetry is coming to Serial port
    #define BOOTTIME 2000 // Time in milliseconds that we show boot loading bar and wait user input

    "

    Compiled by arduino 1.0.1 using "Arduino nano w/ ATmega 328" board settings.

    Now MinimOSD waits for mavlink heartbeats all the time. Xbee works as usual.

    If there is any trick?

    I would appreciate any help...
