Hi, I would like to use I2S with built-in ADC to capture stereo audio. I have read the ESP-IDF, seems only the first built-in ADC can be used in I2S. Am I wrong? Thank you in advance!sevenberyl Posts: 3 Joined: Tue Jul 05, 2022 3:37 am Re: I2S with built-in ADC to ...
Hi I have bought ESP32-S2 board and tried its i2s built-in ADC. But it did not work. The error showed "I2S_MODE_ADC_BUILT_IN' was not declared in this scope". So if someone knows that whether ESP32-S2 support i2s built-in ADC? Thanks a lot!
// In order to be compatible with esp32 and esp32s2, the Tx and TRx of i2s channel use the same controller. // However, there is a problem that if RX channel is enabled and then TX channel is enabled, RX channel needs to be turned off first, // which will cause it to be turne...
more detail: some registers can't be access when codec is suspended. please checkthesofproject/linux#2226to recall everything. ACK, I verified it by applying prints in regmap. More Explanation on SDW error log Attached: RanderWangremoved their assignmentOct 21, 2020 ...

So, in case this flag is set, converter will be enabled? I'm not sure how can I set it. Should I jsut add I2S_MODE_PDM in MODE section? Code: Select all i2s_config_t i2s_config = { .mode = I2S_MODE_MASTER | I2S_MODE_RX | I2S_MODE_TX | I2S_MODE_DAC_BUILT_IN | I2S_MOD...
I added youri2s_configupdates immediately after settingbits_per_chan = 0inmachine_i2s_init_helper(). I still get a ESP32 message (not micropython) when restarting I2S >>> import easy_wav_player I2S(id=0, sck=6, ws=7, sd=3, mode=5, bits=16, format=1, rate=16000, ibuf=40000) ...
