Other Parts Discussed in Thread: BOOSTXL-AUDIO,
Hello,
Let me ask about behavior of audio output when user use "BOOSTXL-AUDIO_430BOOST-SHARP96_FFT_FIR_LEA_MSP430FR5994"
According to following user's guide, user can use FIR mode without LCD.

Then, I'm tring to perform "FIR-Filtering" mode by pushing S1 switch.
When FFT mode, I could see following expected waveform at "input of OPAMP(ch2)" and "output of OPAMP(ch1)".
However, when I change to "FIR filtering", output is disappeared and I could hear any sound from both microphone and speaker.
If you have any procedure except written in above user's guide, Could you please let us know ?
Best Regards,
