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Here is how it looks: (This video is a bit outdated, sorry.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.)

The MinimOSD-Extra project is here: Link

This project is the developing version of the official Arducam OSD located here: Link

The latest stable version is: 2.2

The latest version can be downloaded from here: MinimOSD-Extra R800

CT is included. (The FW for Plane, Copter, Character upload and the character file is in the "FW & Char" directory inside CT directory)

We are sharing it to see videos you make using it! :)

      • well im not sure on that. I think the parameters are minimosd extra's thing. Something Gabor changed or something. On arducam osd they are not needed...

    • What is it connected to, Pixhawk or APM?

  • Are there any plans to add support for functions in Minimosd with KVTeam mod, would like to monitor my second battery I use for my gimbal.

    • Hi,

      Please try the attached FW.

      I did a very fast addition to normal battery voltage panel, just to see if it works.

      After you have tested it we can step forwrd.


      • Gabor,

        Once this is tested will you be writing a "code" for Bat2 for the copter version?

        I imagine a Bat2 addition to the R800 which is working flawlessly.

        I know we are pretty close to the memory limits of the MinimOSD and thus the charset upload code was removed but perhaps after perfecting the Bat2 we can we add HDOP which is so needed to establish what kind of GPS signal we are getting on a particular we all know, number of satellites alone doesn't cut it!

        Thanks for all your work and all the other developers....after all these years of hard work I believe we are pretty close to perfection of the MinimOSD.

          He mentioned earlier but HDOP is indicated by the flashing satellite. Anything over 2.0 causes the GPS icon to blink so it's already included.
