Movie2serial: limit on the number of LEDs per teensy?

I was using my teensy to project an image to an array of 32x115 LEDs. That worked great but when I tried to expand to 32x230 LEDs, the movie2serial program gets hung up when it writes to serial. I thought the teensy could handle it because it runs the rainbow example script on this array with no problem.

Wow, that's 7360 LEDs!

This might be beyond the limits on the Teensy side. Maybe.

Even though you've probably only edited a couple lines, could you please post the exact files you used? That'll save me some time when I try to look into this.

Hey Paul, I edited a bunch of movie2serial. Let me clean it up and post it in a few days.

Here is a link to my code:

I was having trouble with video so I changed it to an image that scrolls Google headlines across it. Another change I made is that it uses a coordinate file (positions2.txt) to choose which pixels to take from the frame.

Interestingly, I just tried this on another computer with the same LED array and it worked. The frame rate did not seem good as the text was scrolling a little jerky.
