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Here is how it looks: (This video is a bit outdated, sorry.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

Try this.


Big Thx, it work.

But ist also no real solution, becouse i also cant upload chars wirh this firmware.


I will do it other way.

Do you still have the time? :)

Ofcourse i will test any firmware try of you

Could you try this one

Also you have to wait 5s after boot to be able to upload charset now.

Now i have to leave for a few hours.

Will continue, ok? :)


The OSD Config Gui, says error entering font mode

and there is also the charset Problem

Restart it.

Also unplug your FTDI and replug it.

Than wait 5s and try it again.

If does not helps, than i missed something.

Will get back soon.

doesnt help

Any way to add the current value. mavlink now sends it out to the mission planner and I display it my Minimosd using the value


I have hard coded a lot of things I use but like what you have done with the config tool.

Other things that you might think about adding is

a. way to change from meter to feet, m/s to mph

b. a way to display a message. (some of us need to display a call sign)




Using Arduino IDE 1.0.1 I am still getting compile errors.  Says conflicting return type associated with uint8_t. Any ideas?

There are 2 source codes in your zip file. Is the OSD the original and the beta your changes?


Just got home.

Does the last one i posted here works well with APM2?

Only char update does not?

I think i have fixed it.

Don't forget to use the config tool in the G1.22.zip because i have made changes there to.

I was able to upload firmware, upload char set, and it seams to work well with my APM1.

So now it is waiting for you to try it on APM2. ;)
