Hi,
I have a ESP32-DevKit-Lipo and need to communicate with ICS43434 microphone through i2s.
My i2s pin setup does not seam to be correct.
.bck_io_num = 26, // IIS_SCLK
.ws_io_num = 32, // IIS_LCLK
.data_out_num = -1,// IIS_DSIN
.data_in_num = 33 // IIS_DOUT
Can someone point the correct pin setup for i2s?
I am using the code here https://blog.squix.org/2019/08/esp32-esp-eye-browser-based-spectrum-analyzer.html
You can use free pin (as long as it is free, and as long as you don't try to use input-only GPI pins for output). On first look the pins you use look fine. Maybe double check your hardware connections.
Do not leave pin 2 (LR) on ICS43434 float. Connect to ground and read data from left channel of i2s driver.
