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Here is how it looks: (This video is a bit outdated, sorry.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

I went out for my first flight tonight but things are not happy on mine. I verified that the OSD settings were still good with "CT Tool for MinimOSD Extra 2.3.2.0 Pre Release r727" config tool but when I flew I had the following issues:
1. Voltage and some other items were not displayed
2. My page would randomly switch to another page that I had never even defined.
I'm digging now and will post video if I can't find anything. Just to be safe I tried to update the Charset (with 12v on the video input pins and USB) but keep getting the unable to update invalid data (charset 2.4).
---
Update 1: Well sure enough once I blew the video up more I released I was getting overscan... the OSD had defaulted back to PAL. So that explains the items off the screen. Still doesn't explain the switching when I have rotation disabled but might have been "rolling" of the image. Going to check now.
Update 2: Yep looks like PAL was causing the DVR to roll over the OSD and display the last couple of lines of the OSD at the top of the screen which made it look like a "new page". So that is solved.
Timer works though! ;-)
I'll start a new post for my charset woes and post a video when I have a proper one with everything set to NTSC lol.
Here is a video with MinimOSD 2.4 r785, which runs trouble free :)
About some improvement suggestions : it would be awesome to have an other efficiency indicator, which would allow to have an idea of the remaining distance that can be performed considering the remaining battery and instant speed.
Something like : Efficiency 2 [m] = Instant speed [m/s] * Remaining battery time [s]
It would allow us to determine the most appropriate speed to perform the longer distance.
Thanks again
Hi Pierre,
Great video! Thank you very much!
That efficiency feature is a great one! It would be more or less like plane version.
One thing we need to test thoroughly is the remaining battery time.
As you can see in your video at the beginning remaining time increases and only after a minute or so it starts decreasing.
As time passes in flight it seems to me a good estimation (you have a 6 minutes flight using 66% of battery and it is estimating a 3 minutes remaining time). What do you think about this panel performance?
Relative altitude seems to be working fine which makes me very happy since it simplifies the code :)
Miguel
Hi Miguel,
Yes, current efficiency seems to work fine, even if I would not like to rely on the last minutes as the estimation is based on theoretical battery capacity and current sensor calibration.
I will be more than happy to test a new "Distance efficiency" panel for copter in future releases ;)
Pierre
Thanks Miguel! Just loaded it up. Should get my "spare parts" that I broke on my Quad Mon/Tues and then will give it a try.
Cheers
Tim
I could really use your help, I have not succeeded displaying the aux voltage in the OSD!
I have tried all the debugging techniques I can think of, but it is really hard to debug something that needs it's serial port for receiving data from the Ardupilot. The MavLink .h-files are now exactly the same I generated and am using in the ArduPilot to send the messages.
This "debugging code" in Mavlink.ino never gets called, the values are always the inital ones. I guess that is the problem!
case MAVLINK_MSG_ID_SYS_STATUS:
{
osd_vbat_A = 1.0; //Battery voltage, in millivolts (1 = 1 millivolt)
osd_curr_A = 2.0; //Battery current, in 10*milliamperes (1 = 10 milliampere)
osd_battery_remaining_A = 3.0; //Remaining battery energy: (0%: 0, 100%: 100)
osd_vbat_B = 4.0; //Battery voltage, in millivolts (1 = 1 millivolt)
}
The MinimOSD is displaying the heading number among others, so I know it receives some messages .
Timer not working in MinimOSDExtra_Copter_Prerelease_2.4_r750.
Just done a couple of flights now with this new code and noticed that the OSD Flight Timer just moves from 0 to 1 and then back to 0 constantly (constant reset?).
Anyone else noticed this or know a work around?
Thanks
Tim
Hi Tim,
Yes timer is not working in R750. Thanks for reporting ;)
I've been fixing it last week and will be releasing a new pre-release during this week.
