Hi,

Be sure you have the eeprom in the correct voltage range. You nedd the one that can work from 2.7V.
Here is some code that should work. https://playground.arduino.cc/code/I2CEEPROM

Keep in mind that your led's stips require 5V power supply.

The screenupdate sub needs to run on core 1. The code below solved my problem. :D #include <U8x8lib.h> #if CONFIG_FREERTOS_UNICORE #define ARDUINO_RUNNING_CORE 0 #else #define ARDUINO_RUNNING_CORE 1 #endif U8X8_SH1106_128X64_NONAME_HW_I2C u8x8(/* reset=*/ U8X8_PIN_NONE); TaskHandle_t ScreenUpdateHan...

Hi Thanks for your reply, First I used a library from Thingpulse https://github.com/ThingPulse/esp8266-oled-ssd1306 After that I changed to U8x8lib that's from the same maker as U8g2lib.h. Also tested the Graphicstest.ino from the U8g2lib, same problem. All the above lib's working fine until you put...

It must have something to do with the task were my screen update is running because if I update the screen in t...
