For ArduinoMega2560ADK please suggest tvout library without bug...and how to connect Mega to TV rcb cable?
Here
you can find a library with some bugs fixed.
But I don't know how to connect to a Mega.
I have been working on ATMega1284 (which has more ram than Arduino Mega) and made a 352*280 pixel display in one colour, but that colour can be any of 24bit palette, the background colour can also be another colour (not just black). I also have images I can pull off SD Card and display, rotate, scale etc
The output of the AVR goes to a AD725 PAL convertor so I can plug into TV/Projector etc, works perfectly
I used TVout for quite a while before I realised there were issues with the way the H & Vsync were made, so I changed it all for the correct specification timings for PAL
I use alot of AVR assembler as the video processing is very timing sensitive
