Thanks, for the hint. I can confirm, that this is the solution: I used a 10k resistor and it works for me too

Did you try pulling down the RESET-pin after 5V power up ?

After pressing RESET (EN) the Serial Output logs the following: rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 188777542, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:1 load:0x3fff0018,len:4 load:0x3fff001c,len:956 load:0x...

Hi all,
I'm using ESP32 PICO kit V4. After flashing the SW starts execution properly. But after normal power ON, the SW doesn't start automaticly. I have to press the RESET (EN) button. How can I activate the automatic RESET after power ON ?

It is same sketch as posted above. Just 1 line has to be replaced:
uint32_t sample_val[2] = {0, 0}; ---> int32_t sample_val[2] = {0, 0};

Correcting the data type of sample_val to int32_t solved the problem Not it works

Thanks a lot

The microphone data can be captured. But in the Serial plotter I'm facing square wave, but I would expect analog graph. What do I have to change in my Code? #include <WiFi.h> #include "driver/i2s.h" void i2s_config() { // http://esp-idf.readthedocs.io/en/latest/api/perip herals/i2s.html // input i2s...

Hi all, I want to connect the MEMS-microphone ICS43434 to the ESP32. This microphone chip comprises I2S Interface to transmit the audion data stream. There is an "I2S.h" library compatible for the Arduino board MKRZero. I'm looking for a library for ESP32. Has somebody already done the porting or us...
