Okay. My problem has been solved :)
The test clips didn't give good connection. Once I connected without them, everything in capture became clear and without any glitches.
Thank you.

Re: Strange capture of I2C on logic analyzer
Yes, same with devkitc, even when I connect it with jumper wires directly.

Re: Strange capture of I2C on logic analyzer
With 3v3 situation is not better.
Regarding pullup, I thought that configuring it in ESP should be enough, no?

Code: Select all
conf.sda_pullup_en = GPIO_PULLUP_ENABLE;
conf.scl_pullup_en = GPIO_PULLUP_ENABLE;

Strange capture of I2C on logic analyzer
Hi, During debugging code interacting with DS3231 over I2C I noticed that my Saleae analyzer cannot decode I2C signals.
I've minimized example to the following (just send address) to make sure analyzer works:
#include "freertos/FreeRTOS.h"
#include "esp_system.h"
#include "driver/gpio.h ...
