LEDs and Push Buttons

USB Monitor LED (LED11)

The USB monitor LED (LED11) indicates that USB communication has been initialized successfully, and you can connect to the processor using a VisualDSP++ EZ-KIT Lite session. Once the USB cable is plugged into the board, it takes approximately 15 seconds for the USB monitor LED to light. If the LED does not light, try cycling power on the board and/or reinstalling the USB driver (see the VisualDSP++ Installation Quick Refer- ence Card).

When VisualDSP++ is actively communicating with the EZ-KIT Lite target board, the LED can flicker, indicating communications handshake.

Push Buttons (SW8–11)

Four push buttons (SW8–11) are provided for general-purpose user input. Two of the push buttons connect to the FLAG pins of the processor. The other two connect to the DAI of the processor. The push buttons are active HIGH and, when pressed, send a High (1) to the processor. Refer to “LEDs and Push Buttons” on page 1-10for more information. The push button enable switch (SW7) is capable of disconnecting the push buttons from the corresponding processor pin (refer to “Push Button Enable Switch (SW7)” on page 2-12for more information).

The push buttons and corresponding processor signals summarized in Table 2-9.
