Tool/software:

Hello,

I want to know how to change the EQ parameter of TLV320AIC3204. I found that there is no relevant register to control its EQ parameter, but the EQ parameter can be changed in the development tool of the development board. Please tell me the method to debug the EQ parameter.

    Hi Luo,

    Please see the application reference guide for the register locations for the EQ filter (Biquads). Data sheet is not super clear on these register locations.

    For example see the table below which describes the ADC biquad register coefficients and their locations. The biquad tool in the EVM GUI automatically calculates these coefficients and loads them into the device.

    Best regards,
