Hello,
So in my latest project I am using a Teensy 4.0 with the audio board. I noticed however (more like saw on this pin diagram: https://www.pjrc.com/store/teensy40_card10a_rev2.png ). That almost all the pins are used up by the audio library. But here is the thing. My project only uses I2S for sound input from the line level input jack and I2S for the sound output. No SD card, no nothing.
So here is my question. Can I free up some of the pins if I just don't use the SD card for example and remove the SD library from my code?
Thank You.
