    Teensy 4.0 I2S2 configuration....

    Hi All,

    I have a Teensy 4.0 with a sgtl5000 audio shield.
    I am trying to figure out how to setup or configure the I2S2 port.
    I would like to take I2S1 input and patch it to I2S2 output.

    Is this possible?

    Thanks a lot,

    I2S2 is not yet in the design tool. But you can use it pretty easily if you just copy the lines for I2S and add "2" on the end of the name.

    Likewise for the audio connections, you'll need to copy some and change the names of where they connect, and of course give each a unique name. It takes a little imagination and patience to do it without the graphical design tool. If you get stuck and need help, please follow the "Forum Rule". Don't just say it doesn't work, don't make use try to blindly guess, and don't be shy about your code. Show what you actually tried. We can help much better and faster and everybody saves time when you show the actual code you tried.

    I believe I already tried changing the code by adding the 2 at the end and also patching it, but I will try again and if have questions I will post the code I am working with.
