Hi,
I am tryign to dispay characters (black & white) on my PAL TV using an atmega32. I successfully did it. But now I have a doubt in the vertical synchronization sequency.. I am usign fake interlacing ...
According to some books and weblinks, I had written my fake interlacing vertical synchronization code as below..
But now I tried with a single line ie
and it is also working fine without any problem! So what is the need of 8 lines ? Also if I can use a single line, I can save more CPU time also..
