Other Parts Discussed in Thread: CC3200
I have designed custom bluetooth board using TLV320AIC3254.
I found there is DC offset in ADC data(MIC input) around -585 as attached file below.
It should be around 0.
I understand , to remove DC offset, I need to use high pass filter.
But I do not know how to implement high pass filter on TLV320AIC3254,
because there is no document or no source code(script) about that.
Could you tell me how to implement that?
