VE with atmega 644p

[Osgeld]

I am making a stand alone device with the video experimenter as part of the design, due to pin requirements though I find it would be easiest to use an ATMEGA644P. I have not seen anything on using a 644p or 1284p yet, and while I am waiting on the LM1881 to show up, I thought I would ask for any tips for pin assignments and maybe any issues I might have with the library (I use the normal tv out lib on a 1284 all the time)

Thanks In advanced

The Video Experimenter makes use of some special functions on the ATmega328. For example, the analog comparator AIN0 pin on Arduino pin 6 (ATmega328 pin 12). And the external interrupt on Arduino pin 2 (ATmega328 pin 4). And the input capture pin ICP1 on Arduino pin 8 (ATmega328 pin 14).
You’ll need to study the Video Experimenter schematic to match these up with the appropriate ATmega644 pins.
Is that the kind of info you are asking about?

yep

Thanks
