Hi Guys,
just in time sort out I2S and deeper audio for design code framework -
but i am little confused about the Pin Table:
i was not gone in detail further ( names and pins and signals ) just in time - but do we miss here not more as 2 SoC _ pins or is there a typo ?
best wishes

Re: I2S0 I2S1 Pin Querry question
Code: Select all
#define I2S1I_BCK_IN_IDX 164
#define I2S1I_BCK_OUT_IDX 164
#define I2S1I_WS_IN_IDX 165
#define I2S1I_WS_OUT_IDX 165

Re: I2S0 I2S1 Pin Querry question
Yeah looks like WS and BCK are duplicated and should be DATA_OUT and DATA_IN instead?
Re: I2S0 I2S1 Pin Querry question
I also had this presumption, that made me thoughtful -
btw cause left channel only perhabs this "new" code in ESP-IDF look good - try this
have a look we can enable left and right separately, right? do you know, can we this do with I2S0 and I2S1 ?
I2S0 channel 1 (25) is right and I2S0 channel 2 (26) is left -
enable pins: DAC1
enable pins: DAC2
now i studdy , where we connect a digital Microfon ( ICS..) on which pins and
how we setup I2S0 ( or need to activate I2S1 ? ) ..if difference rate/freq/sample
edit: more informativ
