Derek Rodrigues Microcomputer Systems 1 Dr. Veton Kepuska

 Build hardware  Build control circuit  Write microcontroller code  Write EVMOMAPL137 code  Test results

 Must control 512 LEDs  Need minimum 72 io ports  Employ multiplexing

 Microcontroller listens over USART for an 8X8 byte array  Sends data to latch array  Tells which latch to send to cube  Pulls low (grounds) appropriate cube layer(s)

 Performs FFT  Establishes UART communication link  Prepares FFT data in format cube understands (array [8][8] bytes)  Sends formatted data at desirable rate for visualizing 3D translation of 2D FFT
