Read data from SD card, send via serial to 2nd Arduino, convert to integer data


Exactly how much memory are we talking about to require this elaborate scheme ?

I'm using the teensy as my platform to give me more memory and processing power, and the integer values range from 80kb to 150kb. I believe I need to have 2 in memory at a time. One that is actively being displayed, and the second which is being read from serial before replacing the first.

Thank you for taking the time to inquire. I was beginning to wonder if I'd posted incorrectly, due to the lack of responses. I truly appreciate it.
