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Here is how it looks: (This video is a bit outdated, sorry.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

    Gabor (or anyone),

    Could you elaborate on the need to change these parameters as described here in the wiki? Some of my parameters aren't set as the wiki states, however all seems to be working. I am using a 3DR radio in parallel with the MinimOSD extra (tx lead disconnected from MinimOSD). If I am understanding the purpose here, these parameters control the frequency at which certain information is reported to MinimOSD correct? And these parameters should be changed if you are setup as I am with the tx connection from the MinimOSD disconnected? Do these Parameters have any other purpose other than in reporting to MinimOSD? In other words will they have any effect on the operation of either APM 2.5 or on the Mission Planner?

    Regards,

    how is wind speed and direction brought into this module? what sensors are used?

    Hi Gabor,

    very nice enhancement of the MinimOSD code.

    Looking at the code I found one thing:


    Because the angles can be up to +-180 degrees, wouldn't it be better to use int16_t instead int8_t ?


    static int8_t    osd_pitch = 0;                  // pitch form DCM
    static int8_t    osd_roll = 0;                   // roll form DCM
    static int8_t    osd_yaw = 0;                    // relative heading form DCM

    When I roll or pitch my copter more than +-127 the shown value flaps because auf type restriction.

    And also the artificial horizon behaves strange because of the value overflow.

    It is the same in the original MinimOSD code.


    I changed my test code to:


    static int16_t    osd_pitch = 0;                  // pitch form DCM
    static int16_t    osd_roll = 0;                   // roll form DCM
    static int16_t    osd_yaw = 0;                    // relative heading form DCM

    and can see higher angles than +-127 degrees and a correct horizon behavior.

    Bye

    Gabor - no video yet - working on it..

    But I did grab a pic of the Ground Station screen :)

    Hi people!

    No one did fly this weekend?

    Or no issue? :)

  • Lito P December 7, 2012 at 11:25am

    Interesting...

    I was under the impression they'd merged the 2 projects but it looks like the fork's still alive...Going to have grab that new firmware.

    Hi all,
    Just purchased MOSD and I have naive question. What exactly is the difference between MOSD and MOSD Extra? They appear to be quite similar in real life. I must be missing something. Thank you,
    Steven

    Gabor,

    I've been running MOSD-Extra since November.  Just wanted to drop in and say thank you for all the hard work.  I'm still in the process of tweaking my setup but should have some video for you soon.

    Cheers

    Weekend is coming!

    If you go flying and have a recorder, please make videos!

    Thx. :)

    Gábor
