@tcroskey You are correct, the UARTReceivedDataIsAvailable() function never returns true even when I am sending bytes over the wire from my PC to my device. Okay, Now I got to figure out why that is happening. Thanks

I believe I am enabling receive interrupt for the UART. I have updated my question with my initialization function for the UART

It worked, using the 5v rail to power the Arduino and the logic boards and the 3.3v to power the LED on the boards. youtube.com/watch?v=Gr5vzWoasUw

@reemrevnivek - Yes, 8 bits of brightness per color on the RGB LEDs. Sorry I should have been more clear. In other words it takes 3 BYTES or 24 bits for every single RGB LED.

Thats fantastic thank you, I think this is exactly what I am looking for.

12kB a frame and 10 frames a sec for a total of 120 kB a sec. \left( 12 \cdot 10 \right) = 120\mbox{ kB} But you are right that does not make sense. The SD card should be able to keep up at that rate. I will edit the question with my experience with the SD card.
