    How to connect teensy 4.1 with the ICS52000 array?

    The Teensy audio design tool show the following suggestion for connection

    I do not know why pin 21 of Teensy 4.1 is used both as the BCLK and FS?

    That information is a typo (aka wrong)

    AFAIK:
    T4.x:
    MCLK 23
    BCLK 21
    LRCLK 20
    IN1 8

    Thanks for the reply.

    I still do not understand, the pin configuration of a ICS52000 is shown in the figure

    which shows SD, WS, SCK, not the MCLK, BLCK, LRCLK.


    Should I connect the
    "MCLK 23
    BCLK 21
    LRCLK 20
    IN1 8"
    to which pins of the ICS52000?

    I would try

    BCLK - SCK
    LRCLK - WS
    IN1 - SD


    See also https://github.com/WMXZ-EU/microSoun...Hardware-setup
    for attachment of other MEMS microphones
    Edit: The pin numbers in reference are for T3.6, but should give an idea on how to use MEMS microphones with Teensy
