Adding extra functions to MinimOSD

Posted by Gábor Zoltán on July 17, 2012 at 10:15am

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Here is how it looks: (This video is a bit outdated, sorry.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

    Hello,

    I'm still looking for the location or direction on how to read out the Thomas Scherrer LRS lost packets info. from the serial data port on the TSLRS. I'm certain I have seen it somewhere but search as I might, I can't locate the info.

    Any help appreciated,

    Steven

    Hi thomas!

    Thanks for the input. I did try that, and it's the same. No matter what, if the camera is plugged in on boot of the minimosd, the overlay does not appear. I've tried setting panel switch to ch6 and no change.

    I also found that the second panel does not work for me. I saved items on panel 2, and when I switch display I get a blank screen with warnings only at the top (i'm able to use the switch to change back to panel 1, etc). this a whole other issue, and i'm definitely more concerned with the flickering.. but worth mentioning.

    Thank you for your answers! You might be correct, but I find the confusion between id 1 and 34 both in the ArduPilot code and in the MissonPlanner code. Both the .h file and the c# file are generated from the same XML-file.

    When I included the same .h file in MinimOSD I got some errors because some of the variables could not be found in the .h file from ArduPilot. I then manually edited the .h file already present in MinimOSD... Of course the problem lies there! 

    Right now I cannot try this because my FTDI-adapter is missing. (1.5 year old son) :)

    Hi Gabor,

     

    I'm really stumped, I hope you can help. I'm having an issue: when the system becomes powered up all I see is video from the camera, but no overlay. If I unplug the camera, the overlay appears with a grey background - if I plug the camera back in, the overlay stays, but it flickers at a high rate. 

     

    I took a video that follows the above destription (power on & see vid only, unplug camera to reveal osd, replug camera to show overlay flickering) - it's hard to notice the flickering through the video for some reason, but I assure you it flickers and is quite painful to look at lol.

     

    3DR minimosd 1.1 (with 5v bridge is soldered on both sides)

    MinimOSD-Extra_Plane_Pre-release_2.4_r719.hex 

    CT Tool for MinimOSD Extra 2.3.2.0 Pre Release r713

    650TVL Sony Super HAD II CCD camera

     

    I've tried going down in firmware, re-update charset, going to firmware 712, resetting to defaults, powering the osd with independant (from APM) 5v. Still same behavior - really would appreciate any help. 

     

    Best,
    Raph

      I having the exact same problem but it does not flicker. When I power up I only get the live video feed with no OSD. If I unplug my camera the osd display shows up and then I can plug the camera back in and get the osd to overlay my live video feed. Has anyone found a reason for this, from Searching online it appears to be a common problem. I'm assuming my case it's operator error. Lol
