xCORE VocalFusion 4-Mic Kit for Amazon AVS Hardware Manual 9/25
7 General purpose user interface
The BaseBoard has 13 LEDs that are controlled by the XVF3000 GPIO. LED_0 -
LED_11 (D2-D13) are positioned around the edge of the BaseBoard. LED_12 (D14)
is positioned in the middle of the BaseBoard. The LED GPIO output must be set low
to light the corresponding LED.
Four general purpose push-button switches are provided. When pressed, each
button creates a connection from the I/O to GND. To ensure correct behavior, the
port connected to the buttons (P4A) must always be defined as an input.
