I have runned out from any type of workaround, at last i have returned to a older board driver 1.0.4 and set as board type NodeMCU-32s against Esp32 dev module - so looks i have von some speed - thats was visible on screen refresh - but still around 1 hour running board freezing. As extra i have try...

Another try - now the esp32 board driver version was 1.0.6, i have updated the esp32 driver directory in arduino ide settings and i saw a new 2.0.2 board driver, so i maked a update and re compiled again code.

https://raw.githubusercontent.com/espre ... index.json

Now, just with the code on Esp32 without any other connection than micro USB power supply code/esp32 freezed.

Now two things remains, if somebody not have any other idea: the board itself or the code/loop making this halt.

Yesterday i have maked several test runs, using a simple serial.println command to test when stuck the esp32. The result currently esp32 freeze without any SPI OLED connection too, so remains the code, the esp32 board or the analog connection/what use the 3v pin. Now im testing the code with and wit...

And here is the wiring. SAschematic.jpg I have used this tutorial connect Esp32 with SPI OLED: https://www.electronicshub.org/esp32-oled-display/ #define OLED_CLK 18 #define OLED_MOSI 23 #define OLED_CS 5 #define OLED_DC 16 #define OLED_RESET 17 Oled connected to 5V on Esp32 and the build receive po...

#include "arduinoFFT.h" arduinoFFT FFT = arduinoFFT(); #include "SSD1306Spi.h" SSD1306Spi display(17, 16, 5); #define SAMPLES 512 #define SAMPLING_FREQUENCY 40000 #define amplitude 1000 unsigned int sampling_period_us; unsigned long microseconds; byte peak[] = {0,0,0,0,0,0,0}; double vReal[SAMPLES]...

Sounds like a bug. Could it be that your software can get locked up into some kind of loop if something unexpected happens? Ok, i will send the code and a diagram, maybe something will be visible. Since i have posted this ,,error" i have maked few test, leaved running the esp32 without playing any ...

Im using to my project Esp32, because stronger than arduino boards. Im new in using esp32 boards, i have noticed my board after 20-30 minute running - simple halt or i dont know. Arduino IDE gives no warning for code or error and code riunning well. After 20-30 minute i see the connected blinking LE...
