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Here is how it looks: (This video is a bit outdated, sorry.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

    I have MinimOSD Extra Copter 2.2.hex installed.  Running from telem1 port   I have a 3dradio in telm2  When mission planner connected i can see voltage and amp from my pixhawk.  Looking at osd it reports 0 for both along with some of the other onscreen info has 0 for the value.

    Hi

    I'm working on a second MiniOSD board. Old board Aug' 2011(~v1.1)

    First time connecting and I'm getting the message "failed to talk to boot loader"

    Any idea?

    Thanks

    Itzik

      Hi Itzik.....Have you managed to get your Minim to work properly yet?

      I have a clone which had the same 'failed to talk to bootloader' message.

      I found that if the 'video in' and 'video out' pins are disconnected from the board, I can configure the thing fine. If connected, I get the message.

      I couldn't get the thing to work at all with the analogue and digital sides seperately powered, so I soldered the pads and power the board with a dedicated 5v Ubec. Only the Rx lead is connected from the APM telemetry port to the Minim OSD. The quality of all the connections seems to be very important, especially on the video side, so I have soldered those to the board.

      Works perfectly now. Thanks to all those clever people who put this together!

      ?It was a stupid question

      • Bjoern > Itzik Ronen March 1, 2015 at 5:49pm

        no it was not :) If you dont have a ftdi that can connect to the dtr/grn pin, you have to press the reset button on the osd right after pressing connect in the software. So, press connect, and then press press and release the reset button. might take a few tries until you get the feel for the timing.

        For charset upload wait a little longer before pressing reset. Maybe 1-1.5 sec

          Thanks for helping.

          I'm pressing and releasing for the last 24 hr. not working for me.

          I hope I understand your instructions. I actually don’t have "connect" I'm trying to upgrade the osd.

    Need some help!  I received 2x RCTimer v2.0 MinimOSD modules and proceeded to follow the instructions Bjoern posted below.  "... just load the Character_Updater_FW.hex, update charset, and then update to plane or copter firmware thats in the same folder." My current problem is that I get "No Mav Data" showing on my display no matter what I flash.

    I even swapped ports from Telem2 to Telem1 and cables but no improvement.  What am I doing wrong?

    • Steven G > Doug Walmsley February 26, 2015 at 3:59pm
      I'm fairly certain on the Pixhawk there is no need to adjust the settings. I've never adjusted mine and the MinimOSD works fine. Of course, it won't hurt anything if you do change as recommended above.
      • Maciej Karpinski > Steven G February 27, 2015 at 12:48am

        Yes what I understand these parameters are for APM, I havn't set them on my Pixhawk and Minimosd-extra works fine with my Pixhawk.
