Hallo Cédric,
happy to hear the everything is going fine now.
About OSD I had some experience working with another text only chip like the one you're using
(something like STV5730), someone also suggested me to use MAX4356/4455 couple  but it sound
like a really complex thing (something like 186 pin to fit are quite enough) to use something like that
but I recently discovered this product:
Maybe you may find it interesting.
Best Regards,

Ok, the usual #pragma stuff doesn't work but the __attribute__((packed)) works like a charm.

And yes I am working on an onboard OSD (see messages "Protocol for the downlink").

For now I am using a design with a max7456 chip that only allows text. I can already print usual data like speed, altitude, climb rate, etc.

My next goal is to make a graphical OSD with the usual artificial horizon. I think I will be able to publish this next version. The actual version is a mix of open source and not open source stuff and I can't publish it.

You're working on a OSD?

Well, after some research it seems that gcc doesn't like #pragma options but might work with the __attribute__ ((packed)) trick…

I'll have a look tonight…
