I2S GPIO pins?
-
Looking for some help - trying to enable the speaker for a Basic Core in ESPHome.
I need to enter the I2S info such as: .. =
i2s_audio:
i2s_lrclk_pin: GPIOxx
i2s_bclk_pin: GPIOxxCan anything kindly confirm which GPIO pins show I use for this? Thanks

many thanks @felmue - got that working via PWM as suggested - THANK YOU!!
do the later models, e.g. Core 3 use i2S?

@zalaking The schematic shows the following I2S pins on the CoreS3:
GPIO00 I2S_LRCK, (Mic MCLK)
GPIO13 I2S_DOUT/DAT0
GPIO14 I2S_DIN/DAT1
GPIO33 I2S_WCK (Mic)
GPIO34 I2S_BCK (Mic)
