LEDs and buttons
LED indicators on the STM32 controller board
The green LED (LD2) indicates that the demonstration kit is in operating mode. When it is
switched on continuously, the PC USB demonstration kit is active; when it flashes, the card
operates in the record-replay. The red LED (LD1) indicates the selected audio output. LD1
switched on continuously indicates that the TS2012 power output is used. By default, LD1 is
switched off and the onboard speaker is selected.
LED indicators on the TS4657 audio card
The TS4657 audio card board features one green LED (LED1). It indicates that the +5 V
supply voltage is present on pin 2 of the I
B1 button on the STM32 controller board
B1 button is used to switch between audio outputs and also between demonstration kit
operating modes. To switch from onboard speaker to TS2012 power output, briefly press B1.
To change the operating mode from PC USB demonstration kit to record-replay, press B1 for
approximately 1s.
