Well, today I again used the standard TVOut Pal Demo but this time something of my own.
We have a NextBase dual screen portable DVD player for keeping the kids occupied in the car. Fantastic invention, would recommend to any parent who has to drive more than an hour with small kids.
While wiring it up I saw the Video port says in/out, so it is Composite, so should work with the Arduino/TVOut combo.
1 re-purposed headphone lead and a couple of resistor later and I had the Arduino outputting video to the NextBase screen.
This means the 14" portable in the garage is now redundant as this is far more compact.
Below is a short video showing it working.
I'd suspect there may be many a household with one of these lying around. Either with the DVD player part broken or because the kids have upgraded to a Nintendo or iPad. So, ready to become part of the tinkers box of bits.
Update: I did a bit more coding and managed to creat my own bitmaps and get them to move down the screen. Not a major achievement but a step in the right direction.
The following video shows it. There are 6 bitmaps all 7x7. The program selects a random column to start and then scrolls the graphic down the screen.
