MinumOSD

Postby Kisssys » Fri Jan 23, 2015 7:11 pm

I know their were a few people who have tried to use the MinumOSD in the past so I thought I would upload my code and a schematic on how to implement it with the M4V2. I don't have any intention of supporting the code but it's attached and a hex file.

Cheers

Wow very nice! I have been wondering about this, and you explained everything! I look forward to trying FPV from my M4 very soon.

Thanks for the write up and detailed pix. I was wondering how this would be done. I want to do a 250mm FPV quad with brushless motors using a BLDC board. First, I have to get my bearings with my M4/Kisssys/Ladybird setup that I'm currently fighting with.

I think the M4 makes a great FPV machine and the 250 size is perfect. I have 2 flying with Kiss 18a esc's one on a scratch built frame and another on the HK FPV250 frame. The scratch built one uses a KX2 camera with micro servo and a Fpvhobby 5.8ghz TXhttp://fpvhobby.com/229-new-mini-58-ghz-avtx-for-fatshark-.html. I use the MinumOSD for 5 volt power for the M4, video camera and the TX. It weighs 400grams AUW, the HK machine weighs 500 grams. Both have Emax Mt1806 2280kv motors.

I've had the H version go over 26 m/s with all the FPV junk removed and 3 cells. That's probably not the limit but I had limited space and to be honest I couldn't see the little thing. You almost need to be FPV to fly it full throttle or it gets out of view in seconds.

With the Kiss ESC's are you using Quatos?

Yes it's Quatos with the Kiss ESC's. I don't use PID.

Would this be a drop in replacement for the MinumOSD? It's based on the MinumOSD, so I'd think it would work.

I think Steve is using the MinimOSD by RCTimer: http://www.hobbyking.com/hobbyking/stor ... _v1_1.html

I also think "Minum" is a new word creation from a mixture of Minim and minimum. ;)

The last few I've bought from Mr. Clone http://witespyquad.gostorego.com/minimosd.html for $10 USD but the RCtimer unit I believe is the same. Diydrones sells it for $49http://store.3drobotics.com/products/apm-minimosd-rev-1-1

I have removed a lot of the icon's which my old eyes see as blobs. The Throttle value is the actual value. The landing gear selects the second page that is a little different but it's mainly the addition of Lat Lon. Most things work but since I don't use them all I'm sure their is something amiss. The code is modified code that is geared for the Arducopter and they do a lot of things specific to that operating system. Artifacts of that are surely present in my modified code.

The basis for the code and the configuration utility and character sets are from this site.
