Hi all,
I encounter the TDM microphone array ( 16 mics),which is very interesting for me
The details can be found here https://www.invensense.com/download-pdf/an-000094-tdm-microphone-array-demo-board-guide/
I would like to read the audio signal of the array using either Rasperry Pi ( or even computer)
However, as i has no knowledge in electronic, i could not make use of the board.
As i try to read from the board guide
and the PI GPIO layout https://webofthings.org/wp-content/uploads/2016/10/pi-gpio.png
I think,
to power the board, i can connect the PI GPIO 3.3V+ground to the J9 jumper.
to read signal, i need to connect Pin5 of J1 to any GPIO of PI. Let assume GPIO4
However, I dont know what should be the correct way to read the stream data form the TDM board
whether the data is interleaving or non-interleaving, block size, bit format.....
As i could not find any document. Please help me on this. Thank you very much
