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Here is how it looks: (This video is a bit outdated, sorry.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

Username: MinimOSD_Extra

Password: Top_Secret

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! :)

  • Another "test" video for you G :D

  • Hi,

    I have an idea for an addon for osd/apm, not sure if it can be done but I thought I would bring it to the experts to see what you guys think.

    I have been wanting a thermal camera for a while but the price is too high for me. I found this the other day, it is a sensor that is about $86 that I think may be able to give our fpv cameras a kind of thermal imaging ability.

    here is the sensor and data sheet (I think this is the correct sensor or the one we would want to use) MLX90620 IR-array sensor

    datasheet MLX90620

    here is a project that gave me the idea, this one uses a different sensor but he is working on a version 2 that uses the sensor above. it also uses arduino and has sketch files on this page.

    here is another project someone else is doing that is an addon for android and iphone, it uses bluetooth.

    it seems they are using the output from the sensor and overlaying the data from it on the video from the camera.  I thought this might be able to be done with the osd (like instead of having 2 screens,of osd data one could include the data from the sensor.  the sensor uses I2C so I dont know if it could attach directly to the osd, but maybe it could connect to the apm??

    I dont have any idea if this is possible but thought it would be cool if it is, I think it would be the first osd to offer thermal imaging as an option. :)



  • Question?
    I am having a weird character issue, that is, something unknown  showing up. It only shows when I switch to panel 2. It says "PM nnnF and keeps  counting up. (see pic) Can anyone tell me what this is and how to get rid of it? Thanks for any help -

  • Hi,

    Today I've tested r463c

    First video is from 2nd flight:


    1-Timer should pause during summary presentation (more considerations about this in the next video).

    2-Has Lito P already noticed, temperature is shown 10 times greater than it should (I checked that with the telemetry logs).

    3-Ground speed is allways zero. Allmost near the end of the flight it starts working. Same happens with distance traveled but that's a consequence since it is calculated based on speed.

    4-Some times climb rate shows -0 (zero with negative sign).

    5-Latitude and longitude seem to have big time intervals without changes.


    Second video (first flight with sencond battery):




    1-Timer reset worked as it should.

    2-Summary keeps updating distance traveled (I wonder if it is calculating distance traveled based on last velocity before summary as been presented).


    Seems we have a little bit of work in our hands :)




  • Had a good flight today:

    Panel switching is working

    Warnings are turned off

    removed panels I wasn't using

    Weird thing is those weird temp #'s are back again...I had them working then they stopped and starting showing in the's probably an issue with my setup.

    I do not have RSSI configured.

  • Here's a flight for you Gabor.


    This was on the tricopter that crashed a few days ago - not bad for 20m fall eh?

    I turned everything on and squeezed a quick flight in before the sun went down...I'll try to do a more thorough test tomorrow.  I'm having trouble with panel switching and not sure what to diagnose.  I'm running my MOSD in master mode (no telemetry) hooked into S3 of my Crius.

    My recorder battery went dead 5 seconds before I landed (due to cold) so I couldn't get a flight summary.  Will try to get more thorough info tomorrow.
  • Ah well - they can't all be successful flights - I pared down my OSD to just the basics...I liked where at least that was...although - I'm a little curious as to where the temperatures are reading from...I'm in the snow and it was reporting 100 degrees C.

  • Hi garbor,

    is it possible to decrease the size of fonts on screen.. thanks

  • Hello,

    I was able to test r462 last thursday. At 6:20 (9:35 in osd timer) time/distance resets.

    I've already digged through the code but can't find a reason to

    FTime became = millis() / 1000 (or at least is what it seams).

    Can someone help plesase?



  • I'm using the arduscam 2.0.The warning signals on my OSD can be barely seen. When I arm/disarm, the the arm/disarm warning signals flickers for a quick second. I have to use the mission planner on my netbook to verify the status whether the multicopter has been armed or disarmed. Is there a setting in the config tool I can adjust to make the warning signals appear longer on the screen, so it can be read?
