tvout & Nano v3.0

Other Hardware Displays

Hi all,
I have just got a nano v3.0 and I am planning to create an asteroids game using the tvout library (in an altoids tin). I have looked at the google code page (Google Code Archive - Long-term storage for Google Code Project Hosting.) and am wondering how to wire up the hardware...

What are OCR1A and OC2A that are mentioned, and where can I read more about whatever these are?
Which pins would I connect to, as my board is based on the ATmega328, which should be (sync - B1, Video - D7 & audio - B3), but it has (A0 .. A7) & (D2 .. D13) labelled on it?

Thanks,
Andy

I think I've got it...
The pins referred to are the chip pin names (found on the schematics), the equivalent board pin-outs for the Arduino Nano v3.0 are...
Video - D7
Sync - D9
Audio - D11

I'll post again when I get it working.

The reference to OCR1A is probably wrong since that is the name of an internal register within the microcontroller. It probably should refer to OC1A which is the name of a pin. OC1A is digital pin 9 in Arduinospeak and OC2A is digital pin 11.

I had fun implementing Asteroids using TVout. bootsandall, maybe you can improve it!
