Which pins numbers to use for ESP32-S3?
i2s_pin_config_t pin_config = {
//.bck_io_num = , // ?? Serial Clock (SCK)
//.ws_io num = , // Word Select (WS)
.data_out_num = I2S_PIN_NO_CHANGE, // Not used
.data_in_num = 1, // Serial Data (SD)
};
My attempt to make an Audio Spectrum Analyzer with 32 bands and I2S with a LilyGo ESP32-S3.
(I have working code for the ASA but without I2S functionality)
I am using an audio line input into gpio 1 in the S3.
I think this is what I need, but I am not sure.
In the LilyGo ESP32-S3 the display is integral with the processor.
i2s_pin_config_t pin_config = {
.bck_io_num = 4,
.ws_io num = 5,
.data_out_num = I2S_PIN_NO_CHANGE,
.data_in_num = 1
};
"chat..." generated code (seems to me) does not recognize the S3 and gives 27, 26, and 25 pins ?
My LilyGo ESP32-S3 is the one with 2 rows of 12 pins ea.
