TV-OUT not aligned properly

Using Arduino Programming Questions
1

Hey!

I started playing with the TV-OUT library today. Stripped a cable, followed schematic, etc.
All the code works fine but bits from the top and bottom are cut of and the coordinates X=0 Y=0 Are not in the top left.
I already played with the Video_properties.h But no succes.
Does anybody have any idea why this doesn't work?

Also I'm using TVOUT Beta 1
And I live in europe. (<-- Maybe the configurations have to be changes?)

Thanks, Tim.

All the code works fine but bits from the top and bottom are cut of and the coordinates X=0 Y=0 Are not in the top left.

That looks like a TV adjustment problem. Or, compensate by determining what coordinates result in text just appearing at the top, left of the screen.

The problem is that the Arduino is unable to generate the exact precise timing to meet the PAL or NTCS standard. It's close, but not quite.

As a result some TVs display the image better than others.

You will need to make adjustments to the TV's settings (if you can) to compensate.

Hi timboiscool,

I also tried some TVout code examples without much success. I made the cable up as described here -

http://www.variableindustries.com/arduino-to-tv-adapter/

and then tried the example code in the TVout R5.91 library downloaded here -

http://code.google.com/p/arduino-tvout/downloads/detail?name=TVout_R5.91.zip&can=2&q=

The code compiled ok and did seem to be outputting some garbage on the TV, which is PAL seeing as I live in Australia. I then tried the TvoutBeta1 from here -

http://code.google.com/p/arduino-tvout/downloads/list

but the examples included in it would not compile. Would you mind telling me where you downloaded the library and circuit for the cable that you are using.

Thanks a lot Pedro.
