Hi all
At first, my english is poor. Sorry fot that.
I want to bulid my own TX, based on a ARM Cortex M3 or MEGA2560 board like DIY Mega 2560
or 9XR-Pro with a Color LCD instead a graphic lcd and use it also for Video with a 5,8ghz rx.
How is it possible ?

Displays are completely digital, your video and OSD are analog. Converting and mixing the 2 is a complex thing.

Trampling on the analog signal like common analog OSDs do is a piece of cake, but modifiying the the digital signal that goes to an LCD is much more complex.
Just go ahead if you don't want to believe us
Someone has started a DIY build using similar components that are used on a Horus, could be a stating point.
