Adding extra functions to MinimOSD

I have started to add functions to MinimOsd code.

At first i did it for myself only. Added many functions i thought i need. Then opened this thread.

after a while, Pedro and later Miguel came, and things started to happen fast. :D

They have optimised the code and added even more things to it.

They have worked hard on CT, and it became a great tool!

Thank you Bough! :)

By now MinimOSD-Extra got a pretty advanced OSD.

Here it is in action:


- Changeable unit measurement (US, metric)

- Airspeed

- Home alt

- Battery Percent

- Battery used mah

- Current Draw

- Time From Startup (cleared at takeoff to show exact flight time)

- OSD Menu

- Variometer

- Wind horizontal speed and direction, and also the average wind speed of the last few minutes. 

- OSD on/off

- Switchable secound screen

- WP distance

- WP heading

- Crosstrack error

- Warning messages for Lost GPS fix, Stall, Overspeed, battery volt, battery Percent, RSSI

- Efficiency, glide distance & thermic notifier. 3 in one panel

- OSD Brightness

- HAM Call Sign

- After flight summary

- Trip distance

- Temperature

- Smoothened horizon

- Real heading


- Vertical speed

This functions can be turned on and off, and placed on different screens now, by the Config. tool.

Also RSSI, switching mode and channel and unit measurement, Stall speed warning, Overspeed warning, Battery warning volt, Battery percent warning, RSSI warning,  can be set in new Config Tool.

We built in a new way of setting video standards. Now OSD does not guessing anymore :). You can set it fixed from CT. It is in "Video Mode" menu.

Here is how it looks: (This video is a bit outdated, sorry. I will make a new one soon.)

  • Hi all,
    Just purchased MOSD and I have naive question. What exactly is the difference between MOSD and MOSD Extra? They appear to be quite similar in real life. I must be missing something. Thank you,
  • Gabor,

    I've been running MOSD-Extra since November.  Just wanted to drop in and say thank you for all the hard work.  I'm still in the process of tweaking my setup but should have some video for you soon.



  • Weekend is coming!

    If you go flying and have a recorder, please make videos!

    Thx. :)


  • I forgot to write yesterday.

    The download is up.

    I think i have got it right this time. :D


  • Can anyone send me a tlog of a flight?

    I can't really test it this way... :(

  • Sorry ia have made a bug on TD panel.

    it is correctid in r455.


  • Yesterday i had a little time to work on this.

    I had an idea to measure trip distance, but made MinimOsd full.... :D

    Than Pedro came, and we tryed to make the code smaller. We had a hard time, because we have already did all that was possible. Bud we did find a few things.

    Also had to remove the two least important panel.

    Center and mavbeat. Have anyone ever used tham? :)

    But now, summary is ready, and we have a new panel also! :)

    If this version passes tests well, than this will be the latest stable, and a am afraid that the project has come to an end.

    No more space left.... :(

    If i had more space, i would teach it to even order pizza.... :D

    But that we really don't....

    This is probably a very long shot but is there any chance of someone furthering the work done by hazy to get this firmware to work on Remzibi's OSD (

  • I'm using this camera: (NTSC) and it's ok with the minimOSD. But I tested this one: (PAL) and the text does't show on. Only show the image of camera without the information of minimOSD. What happen? I already save on PAL video mode but nothing...

  • Although i was not able to test it in any ways, i made a download.

    I did because i am not sure that i will have time to work on it in this month.

    r447 has it all. 

    Also the temperature conversation for imperial system users. ;)
