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Here is how it looks: (This video is a bit outdated, sorry.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

HI Hally, 

Very nice and clean OSD. Good work

Please someone help me!

I've tried all things listed on this forum, but still without any result.

When I flash the 2.2 version everything is working, but as soon as I want to try one of the versions with the "Real Heading" turned on, it's a no go :-(

I can see the heading rose moving though.

I've tried all the versions from " Pre Release r676" up to the latest 800.

Even erased the eeprom and started all over........ no luck.

The result I show in the screenshots.

Thanks in advance.



That's the old character set situation.

The problem is the character set loader is missing from the new versions to make room for other code

(at least that is my understanding.)

So load the the new character set with the old 2.2 firmware then load the new firmware like 2.3.

It's all in the order that you do it. 

Thank you David for your quick reply.

Finally result :-)

This is what I did (together with your advice):

1. Erased eeprom (just to make sure that it's a clean start ).

2. Flashed

3. Flashed "Character_Updater_FW"

4. Updated character set "MinimOSD_2.4.0.2"

5. Loaded the 2.4 Firmware "MinimOsd_Extra_Copter_R800" (this shows as "MinimOSD-Extra Config Tool - Pre - Release r788 and  the OSD status like in my jpg file: OSD (1).jpg 

Result BINGO

Thanks again

Super duper!

If the MinimOSD is ever improved hardware-wise the one thing that would solve all this would be more memory. Right now it's like the Green Acres TV show where you have to unplug one appliance to run something else, but we sacrifice because "farm live'n if the life from me". 

Hi David, 

If it is a memory issue, why don't we use the new hardware Witespy micro minimOSD. I was reading that it has more memory, is it correct? and it can have the same firmware of the minimOSD extra.

If I want to add one additional feature like the radar (plane showing flying around the center home) like this photo attached on the current minimOSD. Can we eliminate some features that we don't use and add the radar feature?

if yes, how to do it? and if not, can we do it on the witespy micro minimOSD?

There is still one thing though.

When I want to use another charset (like MinimOSDTinyR800) My goggles wont produce this.

In the OSD-config on my pc screen it oke, but not in my goggles ???

On the goggle screen it still shows the MinimOSD_2.4.0.0 charset......  

Any idea?

Sorry but this would be awesome.

I am not a programmer. Sorry if I gave that impression. 

I have seen that radar feature on the MinNaza project for the DJI NAZA so it can be done just has not been done for the APM/PixHawk. Maybe the developers can help you.

Nice picture of the Vector OSD. I wish the MinimOSD looked that good :-)

No I had not heard of witespy micro minimOSD or that it had more memory. No idea if that information is correct either.

I have not seen that problem Paul. I use FatShark Dominator goggles and have not see that problem but then again I am not running the R800 firmware or character set. Maybe some else has heard it. What goggles are you using, btw?

I am using Boscam GS 920 AIO goggles, but imho I don't think that is the issue.

The goggles only reproduce what they get delivered, or am I wrong?

I hope someone can help me, because I like the small characters in the R800 version ;-)

I download last F/W and now I have to press the reset every time I start the pixhawk

Any advice
