PH2.0-7P: SPDIF, MCLK, IIS_DATA, BCLK, LRCK, GND,
VCC_3V3:
This is the digital audio output extension. For the IIS, BCLK is
2.8MHz, the LRCK is 44.1KHz, the MCLK is 11.288MHz, the DOUT
following the standard IIS data
format and have 16 bits depth. The system is running in master
mode, you should make sure the IIS port of connected device is
running in slave mode.
E
PH2.0-4P: 3V3, GND, .....
GPIO2 and GPIO1 is used to connect a coding key, should be used
for volume control.
F
PH2.0-11P: 3V3, .......
KEY is used for external buttons, refer to the circuit right for key
definitions. The LED pins are used to extend the LED, and are
common-anode connected. You should connect 3.3V to a current
limit resister and then to LED and then to the pin. TX/RX are UART
interface to send events and receive controls.
