TLV320ADC3101EVM-K: On-Board Microphones Recording

User, 

The preset on the ADC3101EVMGUI provides the following information.  Can you tell me if you have made the proper jumper connections and SW2 has the proper settings?

# For normal USB Audio, no hardware change is required. # If using an external interface, SW2.4 and SW2.5 of the USB-MODEVM must be set to HI and clocks can be connected to J14 of the USB-MODEVM.

# # ADC3101EVM Key Jumper Settings and Audio

Connections:

# 1. Insert Jumpers W12 and W13 - mic bias

# 2. Insert Jumpers W4 and W5

# 3. Single-ended input IN1L(P) - EVM Microphone MK1

# Single-ended input IN1R(M) - EVM Microphone MK2

best regards,

-Steve Wilson

Hi, Steve,

Thank you for your prompt reply.

SW2 positions:

LO=1, 3, 4, 5, 6, 7

HI=2, 8 (Sorry, "SW2-2(A1)=OFF" was a mistake)

Jumper Settings:

Installed=W4, W5, W6(1-2),W7(1-2), W8(2-3), W11

Not Installed=W9, W10

Control Software does not recognize EVM without inserting W11.

Best regards,

Nakazono
