Adding extra functions to MinimOSD

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Here is how it looks: (This video is a bit outdated, sorry.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, I am a newb trying to wrap my head around the code, and think I just need some quick answers to get going. I wanted to start by tweaking the panels. To crop the sign and first 3 digits of the GPS coordinates, would it work if I just replace the 11's with 7's like this?

void panGPS(int first_col, int first_line){
    osd.setPanel(first_col, first_line);
    osd.openPanel();
    osd.printf("%c%11.6f|%c%11.6f", 0x83, (double)osd_lat, 0x84, (double)osd_lon);
    osd.closePanel();
}

Changed to...

void panGPS(int first_col, int first_line){
    osd.setPanel(first_col, first_line);
    osd.openPanel();
    osd.printf("%c%7.6f|%c%7.6f", 0x83, (double)osd_lat, 0x84, (double)osd_lon);
    osd.closePanel();
}

That extra space (11 instead of 10) is to pad between the sign and Lat/Lon symbols right?

Also, if I want to eliminate an icon, I know I can edit the charset file. However if I want to make that empty space available I must do that in the code (also make room for more code). If I wanted to do this, for example removing "LAT" and "LON" symbols from the GPS coordinate display, would it go something like this?

osd.printf("%c%11.6f|%c%11.6f", 0x83, (double)osd_lat, 0x84, (double)osd_lon);

Changed to this...

osd.printf("%11.6f|%11.6f", (double)osd_lat, (double)osd_lon);

Also to get a feel of the syntax... "%c" declares a symbol, "%X.Y" declares a string with X total digits and Y digits after the decimal (where the mavlink message is a string of span <=X), and "|" declares a carriage return? I went with Arduino 1.0.1 (Nano...328) for osd work because I read that's what others are using. Should I use 1.0.3 instead? I heard it results in smaller hex's, but not sure if it works with the "arducam" sketch.

I know you're not paid to educate the community on code. So please tell me to buzz off and read some more books if I'm way off base. Thanks! ;)

Just checked the the survey.

Not many responses, but it already cleared a few things.

Thank you all who filled it in! ;)

I will keep it going for a while.

Also someone wrote that he wants OSD brightness.

I had a problem with brightbness also, as my videogoogles have automatic brightness controll. When OSD was on Than it made video dark. So we had to find a way to make OSD darker.

This is already done. We have spent 2 days on it with Pedro because of a logical bug. There is 4 step. You can find it in CT. ;)

What about adding a bigger (more storage) Atmel to the MiniOSD ? - replacing it should not be too huge a task even for those without proper soldering equipment. - and some hot air equpment can even be home-made (see youtube)

the "major" version should have "all" features, and parts be skipped when compiling for original minimOSD devices.

That would be better/cleaner solution that multiple separate projects.

Just made a survey.

I'm curious. :)

Gabor,

Someone called Crashpilot1000 modified your code a little bit to support FrSky RSSI using a pin on the MinimOSD board itself. Is it possible to incorporate that feature into this branch too? See bottom of this page: http://diydrones.com/forum/topics/no-serious-problems-just-some-que...

Hi Gabor,

Why can't I compile it by myself with arduino IDE (1.0.3) to a appropriate size. The hex I've compiled is about 30k - the Atmega328 only has 28k - so what could be the clue?!

Greetings

c

PS: thanks for the great little project!

I would prefer if we could turn off the icons next to the data. Most of them just take up space and the meaning of the data is obvious based on the units or the position we choose to place them. Ideally, the icons and the units would be optional.

How hard would this be?

Any idea how to fix my screen 2 ? It seems corrupt, displaying gibberish and crashing minimosd occasionally. This is with 2.1 firmware, on latest 462 it won't even screen-toggle. I have tried erasing/moving data labels around but no luck.

I have been trying to get my Rangelink rssi to show but still no luck, i have defined the rssi pin in advance parameter list for my arduplane via gcs (didn't recompile) still can get the osd to read my rx raw rssi data, any thoughts?

Hi Gabor,

I wrote a while back about the chances of adding an 'aeronautical units' setting to the CT, with distance in meters, height in feet and speed in knots - not sure if you have given this any more thought or if there is even room left on the board for this extra code? I will try and add the functionality myself if there is room, but the option through the CT would be awesome.

Cheers,

Ian
