OpenPilot OSD prototyping
Posted 23 September 2011 - 04:42 PM
It started from this wire mess:
and evolved into this:
Hardware is old AHRS board + video sync circuitry.

Sambas, to me, you are another openpilot hero.
You are not wrong, "quietly brilliant" is what we call him.

Really nice work !
Which video sync circuitry you are using ?
And what's the resolution you can achive with this solution ?
I read a little bit about the David_Cranor Projet, the resulution seems depending on the processor power, right ?

I've no problem with the missing NTSC Support
Will you publish your software/hardware as OpenSouce? Right near me lies an Olimex STM32F103 Board waiting for some experimental hobby stuff,
and I'm very impressed from your project. I think the MAX7456 is old enough to go in retirement now.

Yes! Its OpenPilot, everything we do is Open Source. The team is going to start helping with it as well, we need the GCS side of it working so it can be configured for example.

I've no knowledge about QT programming, but would like to have a look at the embedded side,
can I find something about this project in the OpenPilot GIT ?

We are working on a board for this and for sure, once we have it a bit more solid it will be in Git but Sambas is leading this but no stress on him to do what he feels like when he has time, its very very early days for this yet which is why this is cool, we can follow it from start to a really cool OSD.

yes I understand this concept. It's one of the reasons why I'm working alone most of the time.. only to have the feeling of control.
(It's my very precious hobby time
I think I talked with you (or peabody, don't know) about this way of work some weeks ago.
Anyway, I found some open source projects out there today, so I've a good base for some own experiences
best (and good wishes for your project, sambas)

I use good old LM1881 to separate composite sync from videosignal. In middle of screen I have 336x192 graphic area (frame around OP logo), and 4x40 lines of text,
Does text and graphics come from the same framebuffer or do you have special code for the text lines that doesn't require a framebuffer?
I looked at the MAX7456 and it doesn't have graphics capabilities at all. There's a lot that can be done with user defined character sets. I used that a lot on text LCDs and good old C-64 computer and you can do nice-looking thing with that technic. But with the "real" graphics we have far more possibilities (as you already showed in you videos) and are already beyond the capabilities of a MAX7456. The end result will be much superior, I'm shure.

Let me know where I can send coffee so you can work on it more hours of the day.

Excellent work Sambas

The "simple attitude indicator" is very visual and self explaining.
