Opentx ARM Cortex M3 Color LCD Output

Post by fearcapone » Tue Oct 18, 2016 11:35 am

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.
