I check GPIO 0, GPIO 12 and GPIO15 and they mantein their correct state in deep sleep forever. I enable the boot messages printed by the ROM bootloader and when the ESP32 wakes up in that strange state I show these messages: [1/19 10:09:06.9]rst:0x5 (DEEPSLEEP_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) ...

Hi, ENVIRONMENT: espressif32@3.3.2 -> framework-espidf @ 3.40300.0 (4.3.0) ESPTOOL -> tool-esptoolpy @ 1.30100.210531 (3.1.0) DESCRIPTION: In some wake ups from deep sleep (whatever the wakeup source programmed), the ESP32 wakes up but it doesn't run the function main() of the code and the micro kee...

Did you solve the error? I have the same trouble

Good morning,

I want to found the library that includes the function adc_i2s_mode_init(). I found the declaration of the function in adc.h but I don't the body of the function in a .c.

I am using ESP IDF version 4.0. How can I change I2S attenuation for using the bus to read from ADC? If I configure ADC 0dB attenuation but when I read the through I2S, values are attenuated 11dB.

I want to use I2S to read directly from the ADC. The problem is that I configure ADC to measure with an attenuation of 0dB but when I read the value of the measurement from I2S, I think the value has been attenuated 11dB. How can I change the I2S attenuation to 0dB? I'm using PlatformIO and ESP- IDF...
