FINAL PROJECT – 8X8X8 REAL-TIME VOLUMETRIC FFT DISPLAY
Derek RodriguesMicrocomputer Systems 1
Dr. Veton Kepuska
OUTLINE
Build hardware Build control circuit Write microcontroller code Write EVMOMAPL137 code Test results
BUILD ARRAY OF LEDS
512 LEDs soldered together into layers
Each layer soldered together till cube is completed
BUILD CONTROL CIRCUIT
Must control 512 LEDs Need minimum 72 io ports Employ multiplexing
WRITE MICROCONTROLLER CODE
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)
WRITE EVMOMAPL137 CODE
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
