Hello guys,
I am struggling to wire up my TDM/I2S array microphones to the Teensy 4.1 board.
Issue N-1: Two I2S stereo microphones
I'm using Infineon IM69D130 Microphone Shield2Go
Datasheet link
Connected by the next way:
While im running next configuration code
only I2S1 generating Clock and Wclock, the I2S2 port not doing it. Do I connect it to the right pins?

Issue N-2: 8 TDM format microphones
I'm using the same Infineon IM69D130 Microphone Shield2Go that can be used in TDM format, next pic taken from the Shield2Go Datasheet Page.5 Datasheet link
I need an advice how to wire up four of this shield to the Teensy 4.1 and some example of code to start working with this configuration.
