Part Number: TLV320AIC3204


Hi,

Customer feedback using the GUI interface does not match the guidance documentation.

Is there any routine reference for heart sound and lung sound?

Thank you

    Hi Rhea,

    What part of the GUI doesn't match documentation?

    We don't have reference code for heart and lung sounds. What is the customer trying to achieve?

    Thank you,
    Jeff McPherson

    Hi Jeff，

    This is the main interface of CS software downloaded from the official website：

    This is the main screen in the manual：

    Some Settings software and manuals do not correspond.

    Thanks~

    Hi Rhea,

    The differences are due to the Windows OS being different. Slight changes were made to accommodate the upgrade however the advice in the user guide still applies. Let me know if there is any confusion on the GUI and I can help clarify.

    Best regards,
    Jeff McPherson

    Hi Jeff,

    1.

    The customer now just wants to input from IN1 and make the audio complete from HPL and HPR output, but the current debugging has no sound.Please help to suggest a solution to this problem.

    2. Another debugging problem, the customer wants to confirm:

    The customer sees that the evaluation board circuit is a direct single-end input signal, and the other channel is not processed.Does the other channel need to be suspended?

    Thanks~

    Hi Rhea,

    1) In order for the IN1 to be played on HPL and HPR, the customer must open "Digital Settings" -> Clocks/Interface -> Audio Interface -> and enable Digital Loopback (p0 r29 bit 4). This will loop the ADC data into the input of the DAC

    2) I don't think I understand this question. The inputs can be set up in either single ended or differential modes. Also the EVM uses all inputs. If the customer is not using any inputs, they should disconnect the input from the PGA using the Analog Settings -> Audio Inputs -> Input Routing menu.

    Best regards,
