Has anyone attempted to display video clips controlled by an Atom? Maybe something that uses external memory and displayed using the atoms ntsc output? I have a robot and wanted it to be able to display short movie clips. Maybe a system to control an external video player by the atom? I was thinking of using my ipod, but the interface looked pretty complicated.
Any ideas would be appreciated.

Not a chance. The ntsc output from the Atom is text and black and white. You need something alot more powerful to do video. It isn't a passthrough like a genlock. Its just raw low rest on/offs to display text(or tile based games).

Nathan: Thank you. I was thinking more along the lines of the atom controlling a seperate video processor or device. I have seen some articles on using an arduino to control an ipod, but I am not into C code. In regards to my other post on NTSC, I hope not to confuse you. I am thinking of two seperate items. the atom running very simple game code for kids, and also the atom controlling a seperate video processor to display short movie clips. I can plug in my ipod to the video out, and run a long movie, but I have no interaction from the robot, and cant easily control short clips if I just plugged in an ipod without being able to control it as well.

Yes, you could control an external device that actually plays the video. That is probably going to be done with a serial conenction or simple logic levels on I/O pins. It's alot harder to generate video or modify video on the fly.

Greetings,

This may be what you are looking for: http://www.4dsystems.com.au/products.php

This company sells serial controlled LCD displays which have a speaker, media card reader, I/O lines and some models include a touch screen. I believe that Sparkfun carries a limited line of their products including their new 4.3" touch LDC for $140. They sell smaller versions for around $50. Their documents claims that you can load a movie/graphic on memory card and write a script which can display the media to the LCD I believe via a serial command (I have not personally used that function of the display yet).

I also have some videos from youtube linked from my blogspot which is thenerdbench.blogspot.com (the videos are from 4D Systems)

Again...may be what you are looking for...take a look at the videos.

Nathan: I plan to "add pages" to my blogspot which feature some basic projects using the BasicMicro Nanos. I really enjoy working with the Nanos and have all sorts of future projects that I want to use them in!

Thanks-Brian
