 GPIO and UART. The behavior is as follows: GPIO and UART. The behavior is as follows:
    
-  * The 16 User LEDs are tied to the 16 User Switches. While the centerUser button is pressed, the LEDs are instead tied to GND +  * The 8 User LEDs are tied to the 8 User Switches. While the centerUser button is pressed, the LEDs are instead tied to GND
-  * The 7-Segment display counts from 0 to 9 on each of its 8 digits. This count is reset when the center button is pressed. Also, single anodes of the 7-Segment display are blanked by holding BTNU, BTNL, BTND, or BTNR. Holding the center button blanks all the 7-Segment anodes.+
   * An introduction message is sent across the UART when the device is finished being configured, and after the center User button is pressed.   * An introduction message is sent across the UART when the device is finished being configured, and after the center User button is pressed.
   * A message is sent over UART whenever BTNU, BTNL, BTND, or BTNR is pressed.   * A message is sent over UART whenever BTNU, BTNL, BTND, or BTNR is pressed.
-  * The Tri-Color LEDs cycle through several colors in a ~4 second loop +  * The onboard OLED displays the alphabet then a screen saying "This is Digilent's Nexys Video"
-  * Data from the microphone is collected and transmitted over the mono audio out port.+
