that one is also a little bit heavier, I plan on putting this on a pretty small plane.

There is also another cheaper OSD on HK now similar to the E-OSD but with video in and out instead of just running in parallel.

Can administrator delete those offtopic messages for other devices? Guys, let's keep on topic here, can we help somehow with improving code for G-OSD?

Jancis, I posted that because it looks like its the same exact hardware but cheaper, that is on topic. Your post on the other hand, is off topic. He posted the code on the first post, if you think you can improve it, download it and take a hack at it.

Thanks.

I was working last night with implementing distance calculations using avrfix but but eventually found that it took to much space and didn't have enough precision for short distances...

esreis: But I found a bug in wgs84ToSec100 so now distance and bearing works great! Yay!
Of course precision gets worse with longer distances but should be good enough for most people. Still have some testing left to sort out any bugs still there.

When the distance and bearing gets better I'm going to focus on the display design...

I'ts hard to find time to work on this project so thanks for being paitient!

callelj: Was looking like a bug... There will be a precision limitation, but should not be a problem for FPV. Other, more demanding, applications should use larger systems. The G-OSD with this software should be just about perfect for small models in short flights (probably 85% of almost everybody's flights)

Yes, true. Will do some test to see where the limit is for your implementation but my guess is that <1km should work without any problem.

Btw: I saw another osd that set home pos once speed was greater than a limit. I think that's pretty smart.

yes. the best approach, no other things considered, is a button, but may spoil the G-OSD's size and simplicity. The apache OSD (from the same manufacturer as the G-OSD) defines home when senses speed > 10km/h. A tuning gps may send bad fixes with speeds greater than that, though.

There is a button on the G-OSD (The one I have has one).

Hello Friends,
Well, I have the G-OSD and the programmer. As soon as I find some 2mm pins I'll be ready.
I'm wondering how the programmer hooks up to the pins on the board. The board has 6 pins 2mm pitch and the programmer cable has 2.5 mm pitch in two rows of 5 pins. Is there an adapter?

Thanks to callelj and esreis and anyone else who has worked on the software for turning a sows ear into a silk purse.
Thanks again and I will surely send a few bucks your way.
Jerry

Jerry Campbell: No adapter as far as I know. You have to make your own...
Se the project page or first page for pinout on G-OSD.

i3dm: CL-OSD is not ready for use yet. But I hope I will get there soon.

BTW: Thanks for all the donations so far!
I will add all donators to the project page or in the code but if someone don't want that, please tell me.

Today I have done some emulations of different positions.
I selected one position in sweden, one in south america and one in north america.
Bearing and distance was correct for all positions.
I used different distances on all thre points (1km, 500m, 100m).

Also tested different distances at same angle (45 deg) and it gave good bearing and distance up to 10km.
At 25km it gave bad bearing and distance was to low.

So to summarize:
As long as you atleast stay under 10km you should find your way home.
Although I would recomend not to fly more than a 1-2km just to be safe.

Still have some work with GUI but seems like it's moving in the right direction.
